[0039] In this example, after the multiple workpieces 140 are fixed into a stepped structure, the multiple workpieces 140 can be welded together by welding to be processed into a finished product, and the finished product has a stepped structure. For example, the workpiece 140 can be a light cover plate of a battery, and there are two first abutting portions 12, so that the two light cover plates can be fixed to form a stepped structure, and then the two light cover plates are welded to form a finished light cover plate, and the finished light cover plate has a stepped structure that meets the process requirements. Alternatively, the workpiece 140 can also be other types of parts, which can be determined by those skilled in the art according to actual conditions, and are not specifically limited here.

[0040] like Figure 2 As shown, the first fixing body 1 is provided with a first abutting portion 12 on one side of the bearing portion 11. The first positioning member 2 and the first abutting portion 12 are respectively located on two opposite sides of the bearing portion 11 along the second direction, that is, the first positioning member 2 is located on the side of the bearing portion 11 away from the first abutting portion 12. The workpiece 140 is placed on the bearing portion 11, and the first abutting portion 12 and the first positioning member 2 abut against the first and second opposite surfaces of the workpiece 140, respectively, to fix the workpiece 140.

[0041] The first direction may be the height direction of the positioning structure. Alternatively, after the multiple workpieces 140 are stacked and placed on the carrier 11, the stacking direction of the multiple workpieces 140 is the first direction. The second direction may be the length direction of the carrier 11, or, after the workpieces 140 are stacked and placed on the carrier 11, the length of the workpieces 140 is reversed to the second direction. Of course, the width direction of the workpieces 140 may also be the second direction. The first direction is perpendicular to the second direction.

[0042] like Figure 2 As shown, the bearing portion 11 can be a fixed table arranged on the first fixed body 1, a boss is arranged on one side of the fixed table, and a first abutment portion 12 is arranged on the surface of the boss facing the fixed table. The first surface and the second surface of the workpiece 140 are two opposite surfaces of the workpiece 140, and a plurality of first abutment portions 12 can be extended toward the bearing portion 11. By extending each first abutment portion 12 at a different length, each first abutment portion 12 can position the workpiece 140 with a different length from the first surface to the second surface. For example, the first abutment portion 12 has two, the lower part of the boss is provided with a protrusion facing the bearing portion 11, the surface of the protrusion facing the bearing portion 11 forms the first abutment portion 12, and the surface of the upper part of the boss facing the bearing portion 11 serves as another first abutment portion 12. Alternatively, the upper part of the boss can also face the bearing portion

[0043] 11 is provided with a protrusion, the surface of the protrusion facing the bearing portion 11 forms a first abutment portion 12, and the surface of the boss lower part 5 facing the bearing portion 11 serves as another first abutment portion 12.

[0044] In this example, the first abutting portion 12 is detachably connected to the first fixed body 1. For example, the plurality of first abutting portions 12 may also be formed by a plurality of abutting blocks arranged along the first direction. The plurality of abutting blocks may be connected to the first fixed body 1 by studs or bolts, so as to facilitate replacement of the first abutting portion 12 of corresponding size according to the workpiece 140 of different sizes.

[0045] 10 Alternatively, the first abutting portion 12 is a stop block with a stepped structure, and the stop block is connected to the stud.

[0046] Or connected to the first fixed body 1 with bolts.

[0047] The specific structure of the first abutting portion 12 can be determined by those skilled in the art according to actual conditions and is not specifically limited here.

[0048] More first abutting portions 12 may be provided, for example, three or four, etc., and technicians in this field may determine the number based on actual conditions, and no specific limitation is made here.

[0049] In this example, the positioning structure can be replaced with a first fixing body 1 of different structural sizes to adapt to workpieces 140 of different sizes.

[0050] In this example, the first fixing body 1 can be integrally formed.

[0051] Alternatively, the first abutting portion 12 may also be connected to one side of the bearing portion 11 by welding 20 or screwing.

[0052] No specific limitation is given here.

[0053] like Figure 1 and Figure 3 As shown, two fixing bodies can be provided, namely, a first fixing body 1 and a second fixing body 6, and the two fixing bodies are arranged in parallel. Two positioning members are correspondingly provided, namely,

[0054] The first positioning member 2 and the second positioning member 8 can increase the number of workpieces 140 positioned by the positioning structure. Of course, the number of the first fixed body 1 and the first positioning member 2 can also be set to be more, for example

[0055] For example, three or four, etc., those skilled in the art may determine the number based on actual conditions, and no specific limitation is made here.

[0056] In an example, Figures 2 to 4 As shown, the first positioning member 2 is provided with a plurality of second abutting portions 21 along the first direction, the plurality of second abutting portions 21 form a stepped structure, and each of the second abutting portions 21 is suitable for abutting against a second surface of the workpiece 140 , and the plurality of first abutting portions 12 cooperate with the plurality of second abutting portions 21 .

[0057] In this example, the workpiece 140 has a first surface and a second surface opposite to each other, and the first positioning member 2 is arranged on the side of the bearing portion 11 away from the first abutting portion 12, and the first positioning member 2 can abut against the second surface. The second positioning member 8 is provided with a plurality of second abutting portions 21 along the first direction on the side facing the bearing portion 11, and the plurality of second abutting portions 21 form a stepped structure. Each second abutting portion 21 can abut against the second surface of a workpiece 140, so as to fix the plurality of workpieces 140. The first abutting portion 12 and the second abutting portion 21 cooperate with each other to position the plurality of workpieces 140, and the plurality of workpieces 140 are stacked to form a stepped structure.

[0058] Among them, the structure of the second abutment portion 21 can be the same as the structure of the first abutment portion 12. That is, a protrusion extending toward the bearing portion 11 is provided on one side of the second abutment portion 21 facing the bearing portion 11, and the protrusion can form the second abutment portion 21. Alternatively, it is formed by a plurality of abutment blocks stacked along a first direction. The second abutment portion 21 can be detachably connected to the first positioning member 2, for example, the second abutment portion 21 can be fixedly connected by fasteners such as studs or bolts. Of course, the structure of the second abutment portion 21 can be determined by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0059] In an example, Figure 1 and Figure 2 As shown, the positioning structure is further provided with a third abutment portion 13, which is located on one side of the bearing portion 11 along a third direction, and the third direction is respectively perpendicular to the first direction and the second direction, and the third abutment portion 13 is suitable for abutting the third surface of the workpiece 140.

[0060] The workpiece 140 has a third surface, and two sides of the third surface are connected to the first surface and the second surface respectively. The third abutting portion 13 is located on one side of the bearing portion 11 along the third direction and can abut against the third surface of the workpiece 140 to position the workpiece 140.

[0061] In this example, the third abutting portion 13 includes a positioning block and a positioning column, and the positioning column is screwed to the positioning block. Two workpieces 140 are stacked, and the positioning column can abut against the third surface of the upper workpiece 140, and the positioning block can abut against the third surface of the lower workpiece 140. The positioning block of the third abutting portion 13 can also be integrally formed with the first fixed body 1. That is, the first fixed body 1 is provided with a protruding block on one side of the bearing portion 11, and the protruding block can be used as a positioning block, and the side of the protruding block facing the bearing portion 11 can be used to abut against the workpiece 140 to position the workpiece 140.

[0062] In this example, if Figure 2 As shown, the third abutting portion 13 is detachably connected to the first fixing body 1. For example, it can be connected by studs or bolts, so as to replace the third abutting portion 13 of corresponding size according to the workpiece 140 of different sizes.

[0063] Alternatively, the third abutting portion 13 may also be detachably connected to the base 100. Regarding the specific configuration of the third abutting portion 13, those skilled in the art may determine it according to actual conditions, and no specific limitation is made herein.

[0064] In an example, Figure 1 , Figure 2 and Figure 5As shown, the positioning structure further includes a first pushing member 3 , which is slidably disposed on a side of the bearing portion 11 away from the third abutting portion 13 , and can move toward the bearing portion 11 to abut against the fourth surface of the workpiece 140 .

[0065] The first pushing member 3 is located on one side of the bearing portion 11 along the third direction, and on the side of the bearing portion 11 away from the third abutting portion 13, the first pushing member 3 is suitable for abutting against the fourth surface of the workpiece 140. The two ends of the fourth surface are respectively connected to the first surface and the second surface, that is, the fourth surface is an adjacent surface of the second surface and the first surface. For example, the workpiece 140 can be a rectangular plate, and the two opposite surfaces of the workpiece 140 along the second direction are respectively the first surface and the second surface, and the two surfaces of the workpiece 140 along the third direction are respectively the fourth surface and the third surface. The third direction is perpendicular to the second direction, and the third direction is also perpendicular to the first direction.

[0066] In this example, the first pusher 3 is slidably disposed on one side of the bearing portion 11, and when fixing the workpiece 140, the first pusher 3 can move toward the bearing portion 11 to abut against the fourth surface of the workpiece 140. By movably arranging the first pusher 3, the placement space of the workpiece 140 can be increased to facilitate the fixing of the workpiece 140.

[0067] For example, the first pushing member 3 may be a pushing block, and a contact surface is provided on one side of the pushing block facing the bearing portion 11 . The pushing block moves so that the contact surface can contact the fourth surfaces of the plurality of workpieces 140 to position the workpieces 140 .

[0068] like Figure 1 and Figure 5 As shown, the positioning structure further includes a base 100, on which a second guide rail 102 is disposed, and the first pusher 3 is slidably disposed on the second guide rail 102. The second pusher 7 can move along the second guide rail 102, so as to be close to or away from the bearing portion 11.

[0069] In an example, Figure 1 and Figure 2 As shown, the first pushing member 3 is provided with a fourth abutting portion 31 , and the fourth abutting portion 31 is suitable for abutting against the fourth surface of the workpiece 140 .

[0070] like Figure 2 As shown, the first pusher 3 is provided with a fourth abutting portion 31 for abutting against the fourth surface of the workpiece 140. There may be a plurality of fourth abutting portions 31, and the plurality of fourth abutting portions 31 may be spaced apart along the second direction to improve the stability of abutting against the workpiece 140. The fourth abutting portion 31 may be detachably connected to the first pusher 3.

[0071] In this example, the fourth abutting portion 31 includes an abutting block 311 and / or an abutting column 312. The fourth abutting portion 31 may be an abutting block 311 of a block structure, or the fourth abutting portion 31 may be an abutting column 312 of a column structure.

[0072] Alternatively, the abutment block 311 and the abutment column 312 may also be used in combination. For example, the fourth abutment portion 31 includes an abutment block 311 and an abutment column 312, wherein the abutment column 312 is protrudingly disposed at the upper end of the abutment block 311, and the abutment column 312 and the abutment block 311 are adapted to abut against a fourth surface of the workpiece 140 respectively.

[0073] The first pusher 3 is provided with an abutment block 311 on one side facing the bearing portion 11, and an abutment column 312 is protruding from the abutment block 311. That is, the abutment column 312 is provided protruding from the upper end of the abutment block 311 along the first direction. For example, the bearing portion 11 is provided with two stacked workpieces 140, the abutment block 311 can abut against the workpiece 140 of the lower layer, and the side wall of the abutment column 312 can abut against the workpiece 140 of the upper layer. This facilitates the positioning of multiple layers of workpieces 140 of different sizes.

[0074] The abutment block 311 can be integrally formed with the first pusher 3, which is convenient for processing and reduces the subsequent assembly steps. The abutment column 312 can be connected to the abutment block 311 by screwing, which is simple and can improve the installation efficiency. It is also easy to replace the abutment column 312 of different sizes or shapes to adapt to workpieces 140 of different sizes.

[0075] like Figure 2 As shown, in this example, the abutment column 312 is provided with a threaded portion and an abutment portion, and the threaded portion is used to be screwed to the abutment block 311. The abutment portion is provided protruding from the upper end of the abutment block 311, and the abutment portion is suitable for abutting the workpiece 140. A groove body is provided at the end of the abutment portion away from the threaded portion, and the installer can tighten the abutment column 312 through the groove body. Among them, the abutment portion can be a cylindrical, conical or prismatic structure, etc., which can be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0076] In this example, the fourth abutment portion 31 may also be provided as a stepped structure. That is, the fourth abutment portion 31 may be provided as the same stepped structure as the first abutment portion 12, so as to facilitate abutment against the fourth surface of the workpieces 140 of different sizes. For example, when the fourth abutment portion 31 is an abutment block 311, a stepped structure is provided on the abutment block 311, which is used to abut against a plurality of workpieces 140 in sequence. The lengths from the fourth surface to the third surface of the workpieces 140 of different sizes are different. Of course, the structure of the fourth abutment portion 31 may be determined by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0077] In this example, the third contact portion 13 may also be provided with the same structure as the fourth contact portion 31 .

[0078] like Figure 2 As shown, the workpiece 140 has a third surface opposite to the fourth surface, the fourth surface and the third surface are opposite surfaces of the workpiece 140, and the first surface and the second surface are opposite surfaces of the workpiece 140. The positioning structure is also provided with a third abutting portion 13 at a position corresponding to the third surface. The third abutting portion 13 can abut against the third surface. When the workpiece 140 is fixed, the first abutting portion 12, the second abutting portion 21, the fourth abutting portion 31 and the third abutting portion 13 can abut against the first surface, the second surface, the fourth surface and the third surface of the workpiece 140 respectively, so that the workpiece 140 can be positioned more stably, so as to facilitate subsequent processing of the workpiece 140.

[0079] In one example, the first positioning member 2 is provided with a plurality of second abutment portions 21 along the first direction; wherein the first abutment portion 12 and the third abutment portion 13 are detachably connected to the first fixed body 1, and / or the second abutment portion 21 is detachably connected to the first positioning member 2, and / or the fourth abutment portion 31 is detachably connected to the first pushing member 3.

[0080] In this example, the first abutting portion 12 and the third abutting portion 13 are detachably connected to the first fixed body 1, so that the first abutting portion 12 and the third abutting portion 13 of corresponding sizes can be replaced according to workpieces 140 of different sizes. In addition, the second abutting portion 21 is detachably connected to the first positioning member 2, and the fourth abutting portion 31 is detachably connected to the first pushing member 3, so that the second abutting portion 21 and the fourth abutting portion 31 of corresponding sizes can be replaced according to workpieces 140 of different sizes. Of course, the specific connection method of the first abutting portion 12, the second abutting portion 21, the third abutting portion 13 and the fourth abutting portion 31 can be determined by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0081] In an example, Figure 2 As shown, the positioning structure further includes a first placement portion 4, which is located on the side of the bearing portion 11 facing the first pusher 3, and is suitable for placing the workpiece 140, so that the first pusher 3 can push the workpiece 140 placed on the first placement portion 4 to move to the bearing portion 11. By providing the first placement portion 4, it is convenient to place the workpiece 140, and then the first pusher 3 pushes it to a fixed position, so that when the workpiece 140 is directly placed, the interference of the first abutting portion 12 and the second abutting portion 21 with the workpiece 140 can be avoided.

[0082] like Figure 2As shown, the positioning structure is provided with a first placement portion 4 on one side of the bearing portion 11, and the first placement portion 4 is suitable for placing the workpiece 140. The first placement portion 4 can be fixedly arranged on the base 100. The first pusher 3 is located on the side of the first placement portion 4 away from the bearing portion 11. When the workpiece 140 is positioned, the workpiece 140 is first placed on the first placement portion 4, and the first pusher 3 can move toward the bearing portion 11, so that the workpiece 140 can be pushed to the bearing portion 11.

[0083] like Figure 2 As shown, the first placement portion 4 is provided with an escape opening 42 , and the escape opening 42 is suitable for preventing the first pushing member 3 from moving toward the bearing portion 11 .

[0084] In an example, Figure 2 As shown, the first pushing member 3 is provided with a plurality of the fourth abutting portions 31 at intervals along the second direction, and the plurality of the fourth abutting portions 31 can move toward the first placing portion 4 to push the workpiece 140 to move to the carrying portion 11 .

[0085] A plurality of avoidance openings 42 are provided at intervals on one side of the first placement portion 4 facing the first pusher 3, and each of the avoidance openings is suitable for avoiding one of the first pushers 3. So that the first pusher 3 can move toward the bearing portion 11 to abut against the fourth surface of the workpiece 140. For example, each of the avoidance openings 42 can avoid the fourth abutting portion 31 on the first pusher 3. The first placement portion 4 is provided with two avoidance openings 42, and the first pusher 3 is correspondingly provided with two fourth abutting portions 31. The avoidance openings 42 are suitable for avoiding the fourth abutting portion 31. The fourth abutting portion 31 can move in the avoidance openings 42, so that the fourth abutting portion 31 can move toward the bearing portion 11 to abut against the fourth surface of the workpiece 140. By providing two fourth abutting portions 31, the workpiece 140 can be positioned more stably.

[0086] Of course, more fourth abutting portions 31 may be provided, and more avoidance openings 42 may be provided correspondingly. Those skilled in the art may determine this based on actual conditions, and no specific limitation is made here.

[0087] In this example, the first placement portion 4 is provided with a placement platform 41 . The placement platform 41 is suitable for placing the workpiece 140 . The placement platform 41 is arranged higher than the uppermost first abutting portion 12 .

[0088] like Figure 2As shown, the first placement portion 4 is provided with a placement table 41 for placing the workpiece 140. The placement table 41 is provided with an escape opening 42. The first pusher 3 can move away from the bearing portion 11 to move out of the escape opening 42, and then place the workpiece 140 on the placement table 41. Then the first pusher 3 can move toward the bearing portion 11 to push the workpiece 140 to move to the bearing portion 11 for fixing.

[0089] In this example, when the workpiece 140 is pushed, the fourth abutting portion 31 can push the workpiece 140 to move, and can pass through the avoidance opening 42, push the workpiece 140 to the bearing portion 11, and then abut against the fourth surface of the workpiece 140. For example, the abutting block 311 can push the workpiece 140 to move.

[0090] In this example, if Figure 2 As shown, the placement platform 41 is arranged higher than the first abutment portion 12 of the uppermost layer. That is, the height of the placement platform 41 can be higher than the first abutment portion 12 of the uppermost layer. This is to facilitate pushing a plurality of workpieces 140 to the position of the bearing portion 11 in sequence, and to enable each first abutment portion 12 to correspond to a workpiece 140. A negative pressure hole 111 is also provided on the bearing portion 11. When the first pushing member 3 pushes the workpiece 140 toward the bearing portion 11, the negative pressure hole 111 can adsorb the workpiece 140 to prevent the workpiece 140 at the bottom layer from moving to the step of the first abutment portion 12 of the stepped structure during the pushing process.

[0091] In an example, Figure 3 and Figure 5 As shown, the first positioning member 2 is slidably disposed on one side of the bearing portion 11 along the second direction, and the first positioning member 2 is transmission-connected with the first pushing member 3, so that the first pushing member 3 can drive the first positioning member 2 to move toward or away from the bearing portion 11. By transmission-connecting the first positioning member 2 with the first pushing member 3, the convenience of the positioning structure when in use can be improved, and the accuracy of positioning the workpiece 140 can be improved.

[0092] The first positioning member 2 is slidably disposed on one side of the bearing portion 11 along the second direction, and can correspond to the second surface of the workpiece 140. The first positioning member 2 is transmission-connected to the first pushing member 3. That is, the movement of the first pushing member 3 can drive the first positioning member 2 to move. For example, when the first pushing member 3 moves away from the bearing portion 11, it can drive the first positioning member 2 to move away from the bearing portion 11 to open the bearing portion 11, so as to facilitate placing the workpiece 140 on the bearing portion 11, or placing the workpiece 140 on the first placement portion 4. When the first pushing member 3 moves toward the bearing portion 11, the first positioning member 2 can move toward the bearing portion 11, the first pushing member 3 can abut against the fourth surface of the workpiece 140, and the first pushing member 3 can push the third surface of the workpiece 140 to abut against the third abutting portion 13, the first positioning member 2 can abut against the second surface, and the first positioning member 2 can push the first surface of the workpiece 140 to abut against the first abutting portion 12, so as to fix the workpiece 140.

[0093] In an example, Figure 5 As shown, the first pushing member 3 is provided with an inclined portion 32, and the inclined portion 32 is provided with an inclined surface. The first positioning member 2 is provided with a follower portion 22 that cooperates with the inclined portion 32, and the follower portion 22 can move along the inclined surface. When the first pushing member 3 moves away from the bearing portion 11, the inclined portion 32 can drive the follower portion 22 to move away from the bearing portion 11.

[0094] like Figure 5 As shown, the first pusher 3 is provided with an inclined portion 32, the inclined portion 32 has an inclined surface, and the first positioning member 2 is provided with a follower portion 22. The follower portion 22 can abut against the inclined surface, and the follower portion 22 can move along the inclined surface. When the first pusher 3 moves away from the bearing portion 11, the inclined portion 32 can push the follower portion 22, so that the follower portion 22 can move along the inclined surface, thereby enabling the first positioning member 2 to move away from the bearing portion 11.

[0095] The follower 22 may be a cam bearing follower, the cam is rotatably connected to the first positioning member 2, the radial sidewall of the cam can abut against the inclined surface, and the movement of the inclined surface can move the follower 22, thereby pushing the first positioning member 2 to move. The follower 22 can be provided to improve the smoothness of driving the first positioning member 2 to move.

[0096] In an example, Figures 2 to 5As shown, the positioning structure also includes a second fixed body 6, a second pushing member 7 and a second positioning member 8, the second fixed body 6 is arranged on one side of the first fixed body 1 along the third direction, the second pushing member 7 is located on one side of the second fixed body 6 along the third direction, the second positioning member 8 is located on one side of the second fixed body 6 along the second direction, the second pushing member 7 is transmission-connected with the first pushing member 3, the second positioning member 8 is transmission-connected with the second pushing member 7, the movement of the first pushing member 3 can drive the second pushing member 7 to move, so that the second pushing member 7 can drive the second positioning member 8 to move.

[0097] In this example, the second fixed body 6 has the same structure and function as the first fixed body 1. The second pusher 7 has the same structure and function as the first pusher 3. The second positioning member 8 has the same structure and function as the first positioning member 2. The second pusher 7 is located on the side of the second fixed body 6 away from the first pusher 3, and the second pusher 7 is slidably connected to the second guide rail 102. The first pusher 3 can drive the second pusher 7 to move. For example, the connecting rod 110 is connected to the first pusher 3, and the connecting rod 110 can drive the first pusher 3 to move away from the first fixed body 1, that is, the first pusher 3 can move toward the second pusher 7, so that the first pusher 3 is in contact with the second pusher 7, and the second pusher 7 can be driven by the first pusher 3 to move away from the second fixed body 6.

[0098] The second positioning member 8 is disposed on one side of the second fixed body 6. Two first guide rails 101 are disposed on the base 100, which are used to slide and install the first positioning member 2 and the second positioning member 8, respectively.

[0099] like Figure 5 As shown, the first pusher 3 is provided with two inclined portions 32, which correspond to the follower portions 22 on the first positioning member 2 and the second positioning member 8 respectively, so as to drive the first positioning member 2 and the second positioning member 8 to move.

[0100] The positioning structure of the present application is provided with a first fixed body 1 and a second fixed body 6 , so that the number of workpieces 140 positioned by the positioning structure can be increased, thereby improving the applicability of the positioning structure.

[0101] There may be multiple fixed bodies, for example, a third fixed body, a fourth fixed body, etc., and multiple positioning members, pushing members, etc. may be provided accordingly. Those skilled in the art may determine according to actual conditions, and no specific limitation is made here.

[0102] In this example, if Figure 1 and Figure 3As shown, the positioning structure further includes a second placement portion 130 . The second placement portion 130 has the same structure and function as the first placement portion 4 , and is located at one side of the second fixing body 6 .

[0103] In an example, Figure 3 and Figure 5 As shown, the positioning structure includes a first elastic member 5 and a second elastic member 150, the first elastic member 5 is connected to the first positioning member 2, the second elastic member 150 is connected to the first pushing member 3, the second elastic member 150 can drive the first pushing member 3 to move toward the bearing portion 11, and when the first pushing member 3 moves toward the bearing portion 11, the first elastic member 5 can drive the first positioning member 2 to move toward the bearing portion 11.

[0104] like Figure 3 As shown, the first positioning member 2 is provided with a connecting column 24, the movable end of the first elastic member 5 is connected to the connecting column 24, and the fixed end of the first elastic member 5 is connected to the first placement portion 4. The first elastic member 5 can drive the first positioning member 2 to move toward the bearing portion 11 so as to abut against the second surface of the workpiece 140.

[0105] For example, the first elastic member 5 may be a tension spring, one end of which is connected to the first placement portion 4, and the other end of which is connected to the first positioning member 2. When the first pushing member 3 moves toward the bearing portion 11, the inclined surface of the inclined portion 32 moves in the opposite direction, and at the same time, under the action of the tension spring, the first positioning member 2 can be pulled toward the bearing portion 11. Of course, the first elastic member 5 may also be other structures, for example, it may also be set as a compression spring to push the first positioning member 2 toward the bearing portion 11. Those skilled in the art may determine this according to actual conditions, and no specific limitation is made here.

[0106] In this example, if Figure 3 and Figure 5 As shown, the positioning structure further includes a connecting rod 110, which is connected to the first pusher 3. The connecting rod 110 can drive the first pusher 3 to move away from the bearing portion 11 along the second guide rail 102, and the inclined portion 32 can push the first positioning member 2 to move away from the bearing portion 11, thereby opening the bearing portion 11. When the first pusher 3 moves toward the bearing portion 11, the first elastic member 5 can pull the first positioning member 2 to move toward the bearing portion 11, thereby fixing the workpiece 140.

[0107] Among them, Figure 3 As shown, a plurality of connecting rods 110 may be provided, and one end of the plurality of connecting rods 110 is connected to a push block 120. 推The pushing block 120 can drive the plurality of connecting rods 110 to move, so as to improve the stability of pushing the first pushing member 3. For example, two or three connecting rods 110 can be provided, and those skilled in the art can determine according to the actual situation, and no specific limitation is made here.

[0108] like Figure 1 As shown, the base 100 is further provided with a first guide rail 101, and the first positioning member 2 can be slidably connected to the first guide rail 101. By arranging the first positioning member 2 on the first guide rail 101, the smoothness and stability of the first positioning member 2 can be improved.

[0109] In this example, if Figure 3 and Figure 4 As shown, the first positioning member 2 is provided with a limiting protrusion 23. When the first positioning member 2 positions the workpiece 140, when the first positioning member 2 moves to a suitable position, the limiting protrusion 23 can abut against the side wall of the first placement portion 4 to limit the first positioning member 2 from moving too much toward the bearing portion 11, thereby preventing the first positioning member 2 from crushing the workpiece 140.

[0110] In this example, if Figure 1 As shown, a limit block 9 is also provided on the first placement portion 4, and a buffer 10 is provided on the first positioning member 2. When the first positioning member 2 moves toward the bearing portion 11, the buffer 10 abuts against the limit block 9. The buffer 10 can play a buffering role to prevent the first positioning member 2 from moving too fast and crushing the workpiece 140. The buffer 10 can improve the reliability of the first positioning member 2 in positioning the workpiece 140. The buffer 10 can be an elastic buffer structure or a hydraulic buffer structure, etc., which can be determined by those skilled in the art according to actual conditions and is not specifically limited here.

[0111] In this example, the second elastic member 150 is connected to the first pusher 3 and can drive the first pusher 3 to move toward the bearing portion 11. The fixed end of the second elastic member 150 can be connected to the first placement portion 4, and the other end is a movable end, which is connected to the first pusher 3. The push block 120 can push the first pusher 3 away from the bearing portion 11 to open the bearing portion 11. When positioning the workpiece 140, the push block 120 does not apply a thrust, and the second elastic member 150 can drive the first pusher 3 to move toward the bearing portion 11.

[0112] For example, the second elastic member 150 may be a compression spring, one end of which abuts against the first placement portion 4, and the other end abuts against the first pusher 3, and the compression spring can push the first pusher 3 to move toward the bearing portion 11. Of course, the second elastic member 150 may also have other structures, which can be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0113] The second elastic member 150 can drive the first pusher 3 to move toward the first fixed body 1, and the first pusher 3 can be connected to the second pusher 7, so that the first pusher 3 can drive the second pusher 7 to move toward the second fixed body 6. Alternatively, the second pusher 7 can also be connected to the third elastic member alone, and the first pusher 3 is not connected to the second pusher 7. When the first pusher 3 does not apply a thrust to the second pusher 7, the second pusher 7 can be driven to move toward the second fixed body 6 through the third elastic member.
