[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0031] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0032] like Figure 1-Figure 3 As shown, the positioning fixture according to the embodiment of the present application includes a fixing seat 10 and a handle member 20 .

[0033] Specifically, at least one first limiting groove 11 is provided on the fixed seat 10; the handle member 20 is rotatably provided on one side of the fixed seat 10, and a first limiting hole 21 is provided on the handle member 20. The first limiting hole 21 is arranged opposite to the first limiting groove 11 to jointly clamp the workpiece 2, and a movable locking member 22 is provided in the first limiting hole 21. When the workpiece 2 is clamped in the first limiting groove 11 and the first limiting hole 21, the locking member 22 can be moved to stop against the workpiece 2.

[0034] In detail, the first limiting groove 11 and the first limiting hole 21 are arranged relative to each other, so that when the workpiece 2 is loaded on the positioning fixture, the workpiece 2 is inserted into the first limiting hole 21 and the first limiting groove 11 in sequence, that is, the first limiting hole 21 and the first limiting groove 11 are distributed along the length direction of the workpiece 2 relative to the workpiece 2, and the locking member 22 moves from a position avoiding the workpiece 2 to a position stopping with the workpiece 2, thereby clamping the workpiece 2 in the first limiting hole 21. After the processing equipment processes one side of the workpiece 2, the handle member 20 can drive the workpiece 2 to rotate, thereby changing its position relative to the processing equipment. Since the locking member 22 stops the workpiece 2, the center of the workpiece 2 will not shift during the rotation of the handle member 20. Therefore, there is no need to re-calibrate during secondary processing, which improves the convenience of operation and the accuracy of processing.

[0035] In addition, the first limiting groove 11 and the first limiting hole 21 are used to support and position the workpiece 2 from two sections, which can also improve the accuracy and stability of the positioning of the workpiece 2.

[0036] It should be noted that the number of the first limiting grooves 11 is one or more. When the number of the first limiting grooves 11 is more than one, the first limiting grooves 11 are distributed in sequence and at intervals along the length direction of the fixing seat 10 .

[0037] According to the positioning fixture of the embodiment of the present application, the locking member 22 is used to lock the workpiece 2 in the first limiting hole 21 of the handle member 20, and the handle member 20 is used to rotate to drive the workpiece 2 to rotate, thereby facilitating the processing equipment to process the workpiece 2 again without the need for re-calibration, thereby improving the convenience of operation and the accuracy of processing.

[0038] like Figure 1 and Figure 2 As shown, in a specific embodiment, the handle member 20 includes a handle 23 .

[0039] According to the positioning fixture of the embodiment of the present application, the first limiting hole 21 is configured as a waist-shaped hole. In this way, workpieces 2 of different diameters within a certain diameter range can be clamped by simply inserting the first limiting hole 21 and adjusting the locking member 22 to clamp.

[0040] The locking member 22 may be a buckle structure or a bolt structure, etc. In a specific embodiment, the locking member 22 is configured as a bolt, and by rotating the bolt, the bolt can be moved closer to the workpiece 2 until it stops against the workpiece 2 or moved away from the workpiece 2 until it is spaced apart from the workpiece 2.

[0041] like Figure 1 , Figure 4 as well as Figure 5As shown, according to the positioning fixture of the embodiment of the present application, a floating pressure plate 30 is further provided on the fixed seat 10 , and an elastic member 31 is connected between the fixed seat 10 and the floating pressure plate 30 , and the elastic member 31 is used to press the floating pressure plate 30 against the first limiting groove 11 .

[0042] In detail, a floating pressure plate 30 is also provided on the fixed seat 10, and an elastic member 31 is connected between the fixed seat 10 and the floating pressure plate 30. The elastic member 31 can press the floating pressure plate 30 against the first limiting groove 11. In this way, when the workpiece 2 is placed in the first limiting groove 11, the floating pressure plate 30 can be pressed into the first limiting groove 11 by the elastic member 31. When the handle member 20 drives the workpiece 2 to rotate, the floating pressure plate 30 can ensure that the workpiece 2 will not be offset axially during the rotation process, thereby ensuring the concentricity of the workpiece 2 at various locations, thereby improving the processing accuracy of the workpiece 2.

[0043] One end of the elastic member 31 is connected to the floating pressure plate 30, and the other end of the elastic member 31 is connected to the fixed seat 10. The end of the elastic member 31 connected to the fixed seat 10 may be higher than the floating pressure plate 30 or lower than the floating pressure plate 30. In addition, the elastic member 31 may be configured as a spring or an elastic body.

[0044] In addition, for workpieces 2 of different diameters, since the elastic force of the elastic member 31 can be adaptively adjusted, the floating pressure plate 30 is used to press and limit the workpiece 2, which can be applicable to workpieces 2 of various diameters, thereby improving the versatility of the positioning fixture.

[0045] like Figure 1-Figure 3 As shown, in some embodiments, a limit plate 40 is further provided on the fixed seat 10, and the limit plate 40, the floating pressure plate 30 and the first limit groove 11 are arranged in sequence from top to bottom, and an elastic member 31 is connected between the limit plate 40 and the floating pressure plate 30. A first limit member 41 is further provided on the limit plate 40, and a second limit member 32 is further provided on the floating pressure plate 30. The first limit member 41 and the second limit member 32 can cooperate. When the first limit member 41 and the second limit member 32 cooperate, the floating pressure plate 30 is spaced apart from the first limit groove 11.

[0046] In detail, a limit plate 40 is also provided on the fixed seat 10. The limit plate 40, the floating pressure plate 30 and the first limit groove 11 are arranged in sequence from top to bottom. An elastic member 31 is connected between the limit plate 40 and the floating pressure plate 30, so that the structure of the positioning fixture can be reasonably arranged.

[0047] Among them, a first limiting member 41 is also provided on the limiting plate 40, and a second limiting member 32 is also provided on the floating pressure plate 30. The first limiting member 41 and the second limiting member 32 can cooperate. When the first limiting member 41 and the second limiting member 32 cooperate, the floating pressure plate 30 is spaced from the first limiting groove 11. That is to say, when the workpiece 2 is clamped or the workpiece 2 needs to be taken out, the floating pressure plate 30 needs to be spaced from the first limiting groove 11. At this time, it is convenient to place the workpiece 2 into the first limiting groove 11. At this time, the first limiting member 41 and the second limiting member 32 need to cooperate. At this time, the elastic member 31 is compressed. After the workpiece 2 is placed, the cooperation between the first limiting member 41 and the second limiting member 32 can be released. At this time, the floating pressure plate 30 is pressed against the workpiece 2 under the action of the elastic member 31.

[0048] In addition, the cooperation between the first limiting member 41 and the second limiting member 32 can be a snap connection or a threaded connection, which is not limited in the present application.

[0049] like Figure 1 , Figure 4 as well as Figure 5 As shown, in some embodiments, the first limit member 41 is configured as a threaded hole 42, the second limit member 32 is passed through the threaded hole 42, and the second limit member 32 includes a head 321, a light hole segment and a threaded segment 323 arranged in sequence from top to bottom, and the threaded segment 323 can engage with the threaded hole 42.

[0050] In detail, a threaded hole 42 is provided on the limiting plate 40, and the second limiting member 32 is inserted into the threaded hole 42. The second limiting member 32 includes a head 321, a light hole section and a threaded section 323 which are arranged in sequence from top to bottom. The threaded section 323 can engage with the threaded hole 42. In this way, when it is necessary to space the floating pressure plate 30 from the first limiting groove 11, it is only necessary to engage the threaded section 323 with the threaded hole 42. The action force between the second limiting member 32 and the limiting hole enables the floating pressure plate 30 to be spaced from the first limiting groove 11. When it is necessary to press the floating pressure plate 30 against the workpiece 2, the second limiting member 32 is rotated to loosen the cooperation between the threaded section 323 and the threaded hole 42. The light hole section is arranged above the threaded section 323. Under the action of the elastic member 31, the floating pressure plate 30 drives the second limiting member 32 to move downward so that the light hole section moves into the threaded hole 42. At this time, the light hole section and the threaded hole 42 are not matched, and the floating pressure plate 30 is completely under the action of the elastic member 31 .

[0051] like Figure 4 and Figure 5As shown, in some embodiments, the second limiting member 32 also includes a clamping portion 324 connected to the threaded segment 323, and the floating pressure plate 30 is also provided with an assembly hole 33 and a second limiting hole 34, the clamping portion 324 is clamped in the assembly hole 33, and the second limiting hole 34 is located above the clamping portion 324, and a stop member 35 is clamped in the second limiting hole 34, and the stop member 35 stops against the clamping portion 324.

[0052] In detail, the second position-limiting member 32 further includes a clamping portion 324 connected to the threaded section 323. The floating pressure plate 30 is further provided with an assembly hole 33 and a second position-limiting hole 34. The clamping portion 324 is clamped in the assembly hole 33, so that the second position-limiting member 32 can be connected to the floating pressure plate 30, and the clamping portion 324 can rotate relative to the floating pressure plate 30 when the second position-limiting member 32 is disengaged from the threaded hole 42. The second position-limiting hole 34 is located above the clamping portion 324, and a stopper 35 is clamped in the second position-limiting hole 34. The stopper 35 stops against the clamping portion 324, and the clamping portion 324 can be limited by the stopper 35 to prevent the clamping portion 324 from falling out of the assembly hole 33.

[0053] Specifically, during assembly, the clamping portion 324 is first installed in the assembly hole 33, and then the stopper 35 is inserted into the second limiting hole 34. During disassembly, the stopper 35 is first pulled out of the second limiting hole 34, and then the clamping portion 324 is removed from the assembly hole 33. In a specific embodiment, the axis of the second limiting hole 34 is perpendicular to the axis of the assembly hole 33.

[0054] like Figure 3 As shown, in some embodiments, the cross section of the first limiting groove 11 is V-shaped. It is understandable that when the cross section of the first limiting groove 11 is configured as a V-shape, the first limiting groove 11 can better limit the workpieces 2 of different diameters and improve the adaptation range.

[0055] like Figure 3 As shown, in some embodiments, when a plurality of first limiting grooves 11 are provided on the fixing seat 10, the plurality of first limiting grooves 11 are arranged at intervals along the length direction of the fixing seat 10, and the angles between the two side walls of each first limiting groove 11 are different. In this way, more workpieces 2 with different diameters can be further adapted, thereby improving the versatility of the positioning fixture.

[0056] like Figure 2-Figure 4 As shown, according to the positioning fixture of the embodiment of the present application, a baffle 50 is provided on the other side of the fixing seat 10 , and the distance between the baffle 50 and the fixing seat 10 is adjustable, and the baffle 50 is used to stop one end of the workpiece 2 .

[0057] In detail, a baffle 50 is provided on the other side of the fixed seat 10, and the distance between the baffle 50 and the fixed seat 10 is adjustable. The baffle 50 is used to stop one end of the workpiece 2. In this way, when workpieces 2 of different lengths are fixed in the positioning fixture, the distance between the baffle 50 and the fixed seat 10 can be adjusted to stop one end of the workpiece 2, thereby supporting the workpiece 2 and further ensuring the concentricity of the workpiece 2.

[0058] Specifically, in some embodiments, the baffle 50 may be fixed on a screw or a bolt, and the distance between the baffle 50 and the fixing seat 10 may be changed by adjusting the screw or the bolt.

[0059] like Figure 2-Figure 4 As shown, in some embodiments, a clamping groove 51 is provided on the baffle 50 , and the clamping groove 51 is arranged opposite to the first limiting groove 11 , and the clamping groove 51 is used to clamp the workpiece 2 .

[0060] Specifically, the slot 51 is arranged opposite to the first limit slot 11. When the baffle 50 stops at one end of the workpiece 2, the workpiece 2 is clamped in the slot 51, so that the slot 51 is used to support the end face and the bottom of the workpiece 2, further ensuring the accuracy of the position of the workpiece 2 and improving the concentricity of the workpiece 2 during the rotation process.

[0061] The slot 51 extends along the length direction of the baffle 50 .
