DETAILED DESCRIPTION

[0022] The present application is further described in detail below in conjunction with the accompanying drawings.

[0023] Reference Figure 1 The embodiment of the present application discloses a positioning device for stainless steel part processing, comprising a workbench 1, an adjustment plate 2 slidably connected to the workbench, a fixed block 3 detachably connected to the adjustment plate 2, a moving rod 4 slidably arranged on the adjustment plate 2, and three positioning blocks 5 spaced apart on the moving rod 4. During processing, the moving rod 4 is used to drive the positioning block 5 to slide toward the fixed block 3 to lock the part to be processed, thereby ensuring the stability of the part during processing.

[0024] Reference Figure 1 Specifically, the longitudinal section of the fixing block 3 is generally in an "L"-shaped structure, and a fixing member is provided between the fixing block 3 and the adjusting plate 2, and the fixing member is a butterfly bolt that is penetrated through the fixing block 3 and threadedly connected to the top of the adjusting plate 2. In this embodiment, two butterfly bolts are used to ensure the connection strength between the fixing block 3 and the adjusting plate 2. In other embodiments, the fixing member can also be a screw rod and two nuts, that is, the screw rod is penetrated through the fixing block 3 and the adjusting plate 2, and the two nuts are threadedly connected to the two ends of the screw rod respectively.

[0025] Reference Figure 1 Furthermore, a protective layer 31 is embedded on one side of the fixed block 3 close to the moving rod 4. The protective layer 31 is made of plastic or rubber material and has a certain elasticity. When the fixed block 3 cooperates with the positioning block 5 to clamp uneven parts, it is beneficial to enhance the stabilization effect of the parts.

[0026] Reference Figure 2 and Figure 3In addition, the sliding direction of the moving rod 4 moves toward or away from the fixed block 3, so as to cooperate with the fixed block 3 to clamp the locking parts. The positioning block 5 is located at one end close to the moving rod 4 and is hinged with a first connecting rod 41 and a second connecting rod 42. A clearance groove 52 is provided on the side of the positioning block 5 close to the moving rod 4 for the first connecting rod 41 and the second connecting rod 42 to rotate. A mounting block 43 is provided on the side of the moving rod 4 close to the fixed block 3, for the first connecting rod 41 and the second connecting rod 42 to be hinged on the axis. An avoidance groove 431 is provided on the side close to the positioning block 5 for avoiding the rotation of the first connecting rod 41 and the second connecting rod 42. In this embodiment, there are four mounting blocks 43 in total, and they are arranged at intervals along the length direction of the moving rod 4. It should be noted that the first connecting rod 41 and the second connecting rod 42 of adjacent positioning blocks 5 are connected to the same mounting block 43.

[0027] Reference Figure 2 In addition, the positioning block 5 is located between the adjacent first connecting rod 41 and the second connecting rod 42 and is provided with a limit torsion bar 44, which is in a bent structure, and the bend is located at the shaft hinge. The limit torsion bar 44 is made of metal material and has a certain elasticity. The limit torsion bar 44 allows the first connecting rod 41 and the second connecting rod 42 on both sides of the hinge point to rotate or swing relative to each other within a certain range. During processing, the limit torsion bar 44 can be used to absorb and alleviate the impact and vibration of the hinge, so as to ensure the locking effect of the positioning block 5 on the parts.

[0028] Reference Figure 2 Furthermore, the moving rod 4 is provided with an adjustment groove 45 at the connection between the adjacent first connecting rod 41 and the second connecting rod 42 for the mounting block 43 to be slidably connected, and the sliding direction of the mounting block 43 is set perpendicular to the sliding direction of the moving rod 4.

[0029] Reference Figure 2 Furthermore, the positioning block 5 is provided with an arc surface 51 at the corner near the fixed block 3, so that the side wall of the part can be prevented from being worn when the moving rod 4 drives the positioning block 5 to move until the positioning block 5 is pressed against the part.

[0030] Reference Figure 1Furthermore, the adjustment plate 2 is provided with a pneumatic part 6 for driving the moving rod 4 to move. The pneumatic part 6 includes a mounting seat 61 fixed to the top of the adjustment plate 2 and a cylinder 62 arranged on the mounting seat 61. A through groove 611 runs through the top of the mounting seat 61 so that the cylinder 62 can be installed on the top of the adjustment plate 2. A connecting block 621 is assembled at one end of the piston rod of the cylinder 62, and the connecting block 621 is fixed to the side of the moving rod 4 away from the fixed block 3 by bolts. Two guide rods 46 are fixed at intervals on the side of the moving rod 4 close to the cylinder 62, and the length direction of the guide rod 46 is arranged parallel to the sliding direction of the moving rod 4; guide grooves 612 are respectively provided on both sides of the mounting seat 61 for the guide rod 46 to be slidably connected.

[0031] Reference Figure 1 In addition, a mounting groove 11 is provided on the top of the workbench for sliding connection of the adjustment plate 2. A scale 12 is installed on the side wall of the workbench, and a locking piece 7 is provided between the adjustment plate 2 and the workbench. The locking piece 7 is used to adjust the position of the adjustment plate 2 on the workbench and then lock it; before processing, the position of the part can be adjusted indirectly. The locking piece 7 includes a locking rod 71 installed on the two side walls of the adjustment plate 2 and a locking nut 72 threadedly connected to the locking rod 71. Among them, one end of the locking rod 71 passes through the side wall of the workbench, and the workbench is located at the mounting groove 11 and penetrates an avoidance groove 431 for sliding connection of the locking rod 71. The sliding direction of the locking rod 71 is set perpendicular to the sliding direction of the moving rod 4. When fixing the adjustment plate 2, the side wall of the locking nut 72 is pressed against the side wall of the workbench.

[0032] The implementation principle of a positioning device for stainless steel part processing in the embodiment of the present application is as follows: before processing the uneven part, the part is first placed on the adjustment plate 2, and the part is located between the fixed block 3 and the positioning block 5, and then the cylinder 62 is controlled to push the moving rod 4 to move, so as to drive the positioning block 5 and the first connecting rod 41 and the second connecting rod 42 to move until the three positioning blocks 5 are pressed against the side wall of the part; since the adjustment groove 45 is provided for the mounting block 43 to slide, in the process of the positioning block 5 pressing against the part to be processed, the axial hinge of the first connecting rod 41 and the second connecting rod 42 rotates, and the first connecting rod 41 and the second connecting rod 42 of the adjacent positioning blocks 5 are located on the same mounting block 43 and slide in the corresponding adjustment groove 45, so as to ensure that the three positioning blocks 5 are respectively pressed against the same side wall of the uneven part; by using multiple clamping points to act on one side of the part together, and cooperating with the fixed block 3 to clamp the part, the stability of the part during the processing can be enhanced, the processing accuracy can be improved, and the uneven part can be positioned and processed.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
