However, the embodiments do not limit the present invention, and any changes in mechanism, method, or function made by a person skilled in the art based on the embodiments are all within the protection scope of the present invention.

[0026] The terms used herein, such as "upper", "lower", "left", "right", "front", "back", etc., which indicate relative spatial positions, are used for the purpose of convenience to describe the relationship between one feature and another feature as shown in the accompanying drawings. It is understood that, depending on the placement of the product, the terms of relative spatial positions may be intended to include different orientations other than those shown in the drawings, and should not be construed as limitations on the claims. In addition, the descriptor "horizontal" used herein is not completely equivalent to being perpendicular to the direction of gravity, and a certain angle of inclination is allowed.

[0027] like Figure 1-5 As shown, an embodiment of the utility model provides a transfer and placement mechanism 10, which can be used to drive a workpiece 20 so that the workpiece 20 can move along a preset trajectory. In this way, it is convenient for production personnel to install the workpiece 20 in place. The transfer and placement mechanism 10 is suitable for assembling a shift block used in a hydraulic motor. In the following, the transfer and placement mechanism 10 will be described by taking the shift block as an example, and the workpiece 20 refers to the shift block. Of course, the transfer and placement mechanism 10 can also be used to assemble workpieces 20 other than the shift block, which is not limited here.

[0028] For ease of explanation, Figure 1 The coordinate system in defines the X-axis direction, Y-axis direction and Z-axis direction of the transfer and placement mechanism 10. The X-axis direction, Y-axis direction and Z-axis direction are three mutually perpendicular directions, among which the Z-axis direction can also be understood as the up and down direction.

[0029] The transfer and placement mechanism 10 includes a base 1, a first slide 2 slidably connected to the base 1 along the X-axis direction, a second slide 3 slidably connected to the first slide 2 along the Y-axis direction, a third slide 4 slidably connected to the second slide 3 along the Z-axis direction, and a holding member 5 connected to the third slide 4 for holding a workpiece 20. With the above design, the first slide 2 can only move along the X-axis direction, the second slide 3 can move along the X-axis direction and the Y-axis direction, the third slide 4 can move along the X-axis direction, the Y-axis direction and the Z-axis direction, and the holding member 5 is connected to the third slide 4, so that the workpiece 20 held by the holding member 5 can also move along the X-axis direction, the Y-axis direction and the Z-axis direction.

[0030] The first slide 2 and the base 1, the second slide 3 and the first slide 2, and the third slide 4 and the second slide 3 are all slidably connected through standard slide rail and slider assemblies on the market, and the sliding tracks of the first slide 2, the second slide 3 and the third slide 4 are stable and reliable.

[0031] The transfer and placement mechanism 10 further includes a first follower 31 connected to the second slide 3 and a second follower 41 connected to the third slide 4. The first follower 31 can move following the second slide 3, and the second follower 41 can move following the third slide 4. The base 1 has a first cam surface 11 that abuts against the first follower 31 along the Y-axis direction, and a second cam surface 12 that abuts against the second follower 41 along the Z-axis direction; at least a portion of the length of the first cam surface 11 is inclined or extends in a curved shape relative to the X-axis direction, so that when the second slide 3 moves along the X-axis direction following the first slide 2, it will also move along the Y-axis direction under the action of the first cam surface 11 and the first follower 31; at least a portion of the length of the second cam surface 12 is inclined or extends in a curved shape relative to the Z-axis direction, so that when the third slide 4 moves along the X-axis direction and the Y-axis direction following the second slide 3, it will also move along the Z-axis direction under the action of the second cam surface 12 and the second follower 41. The extension tracks of the first cam surface 11 and the second cam surface 12 are set according to actual needs.

[0032] In this embodiment, it is only necessary to drive any one of the first slide 2, the second slide 3 and the third slide 4 to move along the X-axis direction, and the holding member 5 connected to the third slide 4 will move along the Y-axis direction and the Z-axis direction according to a preset trajectory while moving along the X-axis direction. In this way, when the production personnel fix the workpiece 20 on the holding member 5, they drive any one of the first slide 2, the second slide 3 and the third slide 4 to move along the X-axis direction, and the workpiece 20 can be moved to the desired position according to the preset trajectory for assembly.

[0033] The transfer and placement mechanism 10 further includes a handle 6 connected to the third slide 4, and the handle 6 is convenient for production personnel to hold to manually drive the third slide 4 to move along the X-axis direction. It is conceivable that the handle 6 can also be connected to the first slide 2 or the second slide 3.

[0034] When the shift block is installed using the transfer and placement mechanism 10, the shift block is first fixed on the holding member 5, and then the production personnel drag the handle 6 to move the third slide 4 along the X-axis direction. When the third slide 4 moves along the X-axis direction, it will also move along the Y-axis direction and the Z-axis direction according to a preset trajectory. In this way, the shift block can be moved to the exact position in the cylinder of the hydraulic motor under the drive of the transfer and placement mechanism 10 for subsequent assembly.

[0035] The transfer and placement mechanism 10 may further include a support 30 connected to the base 1 , and the support 30 is used to fix the base 1 at a certain height.

[0036] In this embodiment, the base 1 includes a first substrate 13 and a first slot plate 14 connected to the first substrate 13. The first slot plate 14 is provided with a first track slot 15. At least part of the first follower 31 is located in the first track slot 15. The first cam surface 11 is a side wall surface of the first slot plate 14 located on both sides of the first track slot 15 in the Y-axis direction, that is, the first cam surface 11 can be regarded as having two. When the first follower 31 moves in the first track slot 15 along the X-axis direction, the two first cam surfaces 11 will limit the position of the first follower 31 in the Y-axis direction, so that the first follower 31 moves along the Y-axis direction. In this way, the second slide 3 connected to the first follower 31 will also move along the Y-axis direction.

[0037] Furthermore, the position of the first slot plate 14 relative to the first substrate 13 in the X-axis direction can be adjusted. When the position of the first slot plate 14 relative to the first substrate 13 in the X-axis direction is adjusted, the position of the first cam surface 11 will also change accordingly. In this way, when the second slide 3 moves in the X-axis direction, the timing of moving in the Y-axis direction can be adjusted.

[0038] Specifically, the first slot plate 14 is provided with a slot 141 extending along the X-axis direction, and the slot 141 is arranged through the first slot plate 14. The first substrate 13 is provided with a threaded hole 131 corresponding to the slot 141. When the slot 141 and the threaded hole 131 are connected by screws to fix the first slot plate 14 on the first substrate 13, when the screws are not tightened, the first slot plate 14 can be adjusted along the X-axis direction relative to the first substrate 13. After the screws are tightened, the position of the first slot plate 14 cannot be moved relative to the first substrate 13.

[0039] Furthermore, the base 1 further includes a second substrate 16 connected to the first substrate 13 and a second slot plate 17 connected to the second substrate 16, and the first substrate 13 and the second substrate 16 are arranged vertically. A second track slot 18 is provided on the second slot plate 17, and at least part of the second follower 41 is located in the second track slot 18. The second cam surface 12 is a side wall surface of the second slot plate 17 located on both sides of the second track slot 18 in the Z-axis direction, that is, the second cam surface 12 can be regarded as two. When the second follower 41 moves in the second track slot 18 along the X-axis direction, the two second cam surfaces 12 will limit the position of the second follower 41 in the Z-axis direction, so that the second follower 41 moves along the Z-axis direction, and thus, the second slide 3 connected to the second follower 41 will also move along the Z-axis direction.

[0040] The first follower 31 includes a first connecting shaft connected to the second slide seat 3 and a first rolling member rotatably connected to the first connecting shaft. The first rolling member is located in the first track groove 15 and is in rolling contact with the first cam surface 11. In this way, the friction between the first follower 31 and the first cam surface 11 is small.

[0041] The second follower 41 includes a second connecting shaft connected to the third slide 4, and a second rolling member rotatably connected to the second connecting shaft. The second rolling member is located in the second track groove 18 and is in rolling contact with the second cam surface 12. In this way, the friction between the second follower 41 and the second cam surface 12 is small.

[0042] In this embodiment, the first cam surface 11 includes a first rest segment 111 and a second rest segment 112 which are arranged parallel to the X-axis direction, and a first stroke segment 113 connecting the first rest segment 111 and the second rest segment 112. The first rest segment 111 and the second rest segment 112 are staggered in the X-axis direction and the Y-axis direction. When the first follower 31 moves along the X-axis and contacts the first rest segment 111 and the second rest segment 112, the second slide 3 and the third slide 4 will not move along the Y-axis direction, and when the first follower 31 contacts the first stroke segment 113, the second slide 3 and the third slide 4 will move along the Y-axis direction. The movement trajectory of the first follower 31 is shown in FIG. Figure 4 As shown by the dotted line D in FIG.

[0043] The second cam surface 12 includes a third rest segment 121 and a fourth rest segment 122 which are arranged parallel to the X-axis direction, and a second stroke segment 123 which connects the third rest segment 121 and the fourth rest segment 122. The third rest segment 121 and the fourth rest segment 122 are arranged staggered in both the X-axis direction and the Z-axis direction. When the second follower 41 moves along the X-axis direction and contacts the third rest segment 121 and the fourth rest segment 122, the third slide 4 will not move along the Z-axis direction, and when the second follower 41 contacts the second stroke segment 123, the third slide 4 will move along the Z-axis direction. The movement trajectory of the second follower 41 is shown in FIG. Figure 5 As shown by the dotted line E in FIG.

[0044] The first cam surface 11 and the second cam surface 12 are arranged in the above-mentioned track. It is only necessary to drive the third slide 4 to move along the X-axis direction, so that the third slide 4 can move along the Y-axis direction and the Z-axis direction according to the preset track during the movement along the X-axis direction. In this way, the transfer and placement mechanism 10 can drive the workpiece 20 to move to the specified position according to the preset track. Of course, the extension track of the first cam surface 11 and the second cam surface 12 can be designed according to needs, and is not limited to the above-mentioned extension track.

[0045] like Figure 1-3As shown in 6-7, the transfer and placement mechanism 10 also includes a first stopper 7 and a second stopper 8 connected to the base 1. The first stopper 7 and the second stopper 8 are respectively located on both sides of the first slide 2 in the X-axis direction. The first stopper 7 and the second stopper 8 limit the first slide 2. The first slide 2 includes a first position that abuts against the first stopper 7 and a second position that abuts against the second stopper 8, and a first holding mechanism for keeping the first slide 2 at the first position is provided between the first slide 2 and the first stopper 7, and a second holding mechanism for keeping the second slide 3 at the second position is provided between the second slide 3 and the second stopper 8.

[0046] When the first slide 2 is maintained in the first position, the position of the retaining member 5 is also fixed, so that it is convenient to fix the shift block on the retaining member 5. Thereafter, when the first slide 2 slides to the second position, the shift block will also be moved into place. The first slide 2 is maintained in the second position, so that the position of the shift block in the cylinder body of the hydraulic motor can be kept stable for assembly.

[0047] In this embodiment, the first retaining structure includes a first magnetic component 71 connected to the first stop member 7, and a first magnetic portion located on the first slide 2 and capable of magnetically cooperating with the first magnetic component 71. In this way, when the first slide 2 slides to the first position, the magnetic force between the first magnetic component 71 and the first magnetic portion can keep the first slide 2 in the first position. If the first slide 2 needs to slide, the magnetic force between the first magnetic component 71 and the first magnetic portion needs to be overcome.

[0048] The second retaining structure includes a second magnetic member 81 connected to the second stop member 8, and a second magnetic portion located on the first slide 2 and capable of magnetically cooperating with the second magnetic member 81. In this way, when the first slide 2 slides to the second position, the magnetic force between the second magnetic member 81 and the second magnetic portion can keep the first slide 2 in the second position.

[0049] As a preferred solution of this embodiment, the first magnetic attraction member 71 and the second magnetic attraction member 81 are magnets, the first slide 2 is made of ferromagnetic material, the above-mentioned first magnetic attraction portion is the surface close to the first magnetic attraction member 71 when the first slide 2 is in the first position, and the above-mentioned second magnetic attraction portion is the surface close to the second magnetic attraction member 81 when the first slide is in the second position.

[0050] In the case where the first slide 2 is made of non-ferromagnetic material, the first magnetic attraction portion and the second magnetic attraction portion may become a connection block connected to the first slide 2 and made of ferromagnetic material.

[0051] In other embodiments, the first holding structure may also be other structures, for example, the first holding structure includes two corresponding connection holes respectively opened on the first stopper 7 and the first slide 2, and a positioning pin inserted into the two connection holes when the first slide 2 is in the first position, when the positioning pin is inserted into the two connection holes, the first slide 2 can be kept in the first position, and when the positioning pin is out of one of the connection holes, the first slide 2 can slide. The second holding structure may adopt a structure similar to the above-mentioned first holding structure.

[0052] The transfer and placement mechanism 10 further includes a detection element 72, which is used to detect whether the first slide 2 is located at the first position, so as to determine whether the shift block can be placed on the holder 5. The detection element 72 is preferably connected to the first stopper 7, but can also be set at other positions, and only needs to be fixed on the base 1. The detection element 72 can be specifically selected to be a proximity sensor, a metal sensor, etc.

[0053] The second stopper 8 includes a first fixed block 82 fixed to the base 1, and an adjustment structure 83 adjustably connected to the first fixed block 82 along the X-axis direction. When the first slide 2 is located at the second position, the adjustment structure 83 and the first slide 2 are against each other. The adjustment structure 83 is adjusted relative to the first fixed block 82 along the X-axis direction, that is, the second position of the first slide 2 is adjusted along the X-axis direction. Specifically, the adjustment structure 83 includes a bolt threadedly connected to the first fixed block 82, and a nut threadedly connected to the bolt and abutting the first fixed block 82. When the first slide 2 is located at the second position, the bolt and the first slide 2 are against each other. By turning the bolt, the position of the bolt in the X-axis direction can be adjusted to change the second position of the first slide 2. The nut can firmly connect the bolt to the first fixed block 82.

[0054] The first stopper 7 includes a second fixed block 73 fixed to the base 1 and a buffer block 74 connected to the second fixed block 73. The buffer block 74 can be made of elastic material. When the first slide 2 is in the first position, the first slide 2 and the buffer block 74 abut against each other, and the buffer block 74 has a buffering effect on the impact of the first slide 2.

[0055] The transfer and placement mechanism 10 also includes a first elastic member 9 disposed between the second slide 3 and the third slide 4. The first elastic member 9 is elastically retracted along the Z-axis direction. The elastic force of the first elastic member 9 makes the third slide 4 have a tendency to slide toward one side along the Z-axis direction relative to the second slide 3. Under normal conditions, the third slide 4 will be in an initial position under the action of the first elastic member 9. When the third slide 4 is driven to move along the Z-axis direction, the first elastic member 9 is retracted by force. When the third slide 4 is not driven, it will return to the initial position under the action of the first elastic member 9.

[0056] The first elastic member 9 can be a tension spring, a nitrogen spring, etc. Figure 2 In the illustrated embodiment, the first elastic member 9 is a tension spring, the upper end of which is connected to the second slide 3, and the lower end is connected to the third slide 4, so that after the third slide 4 slides downward along the Z-axis direction, it will reset upward when not driven. The tension spring can also be replaced by an elastic member such as a nitrogen spring. It can be imagined that when the first elastic member 9 is a nitrogen spring, if the third slide 4 is intended to tend to move upward along the Z-axis direction relative to the second slide 3, the upper end of the nitrogen spring needs to be connected to the third slide 4, and the lower end needs to be connected to the second slide 3.

[0057] It should also be noted that when a first elastic member 9 that is elastically retractable along the Z-axis direction is provided between the second slide 3 and the third slide 4, the second follower 41 only needs to cooperate with a second cam surface 12. Thus, in other embodiments of the present invention, the second slot plate 17 can be replaced with a first cam block with a second cam surface 12, and under the action of the first elastic member 9, the second follower 41 and the second cam surface 12 are kept in contact along the Z-axis direction.

[0058] Similarly, when a second elastic member that is elastically retractable along the Y-axis direction is provided between the first slide 2 and the second slide 3, the first follower 31 can be matched with a first cam surface 11. In this way, the first slot plate 14 can be replaced by a second cam block with a first cam surface 11, and under the action of the second elastic member, the first follower 31 and the first cam surface 11 are kept in contact along the Y-axis direction.

[0059] like Figure 8 As shown, in this embodiment, the holding member 5 includes a holding block 51, a connecting plate 52 connecting the fixing block and the third slide 4, the holding block 51 includes a bottom wall portion 511, a protrusion 512 protruding upward from the bottom wall portion 511, a receiving groove 513 formed between the bottom wall portion 511 and the protrusion 512, and an elastic abutting member 514 connected to the protrusion 512, a workpiece 20 such as a motor shift block can be placed in the receiving groove 513, and the elastic abutting member 514 can elastically abut the part of the workpiece 20 located in the receiving groove 513, so that the workpiece 20 such as the motor shift block can be fixed on the holding block 51. Specifically, two elastic abutting members 514 can be provided, and abut the two sides of the workpiece 20 in the same direction. The elastic abutting member 514 can be specifically selected from standard elastic plungers.

[0060] The above-mentioned receiving groove 513 can only receive a part of the workpiece 20, and the other part of the workpiece 20 is located outside the receiving groove 513. In contrast, the holding block 51 further includes a support bar 515 connected to the bottom wall portion 511. The support bar 515 is located outside the receiving groove 513 to support the part of the workpiece 20 located outside the receiving groove 513, so that the position of the workpiece 20 on the holding member 5 is more stable. The part of the workpiece 20 located outside the receiving groove 513 is convenient for production personnel to hold to take and place the workpiece 20.

[0061] It should be understood that although the present specification is described according to embodiments, not every embodiment contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0062] The above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person skilled in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
