[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a positioning device for polishing metal parts, including a working panel 1, a fixing plate 2 is connected to the top of the working panel 1 by screws, two vertical plates 3 are fixedly connected to the top of the fixing plate 2, a workpiece baffle 4 is fixedly connected between the top of the fixing plate 2 and the right side of the left vertical plate 3, and a positioning mechanism 500 for positioning metal parts is installed on the top of the fixing plate 2; through the coordinated use of the fixing plate 2, vertical plates 3, workpiece baffle 4 and positioning mechanism 500 on the top of the working panel 1, it is convenient for stable positioning after rough adjustment and also convenient for the operator to judge the point positions, enabling the structure after rough adjustment to maintain a stable state, reducing the possibility of deviation, and at the same time facilitating the operator to visually judge the point positions of rough adjustment and facilitating the adjustment operation, thereby greatly improving the practicality of the metal part polishing positioning device.

[0025] In this embodiment, the positioning mechanism 500 is a structure for positioning and restricting metal parts.

[0026] As Figure 1 , Figure 2 and Figure 3 shown, the positioning mechanism 500 includes a sliding groove 501 opened on the top of the fixing plate 2, a sliding rod 502 fixed inside the sliding groove 501, a sliding block 503 slidably connected to the outside of the sliding rod 502, an adjusting block 504 fixed to the top of the sliding block 503, a positioning rod 505 passing through the left side of the adjusting block 504, a pressing block 506 fixed to the left end of the positioning rod 505, a threaded rod 507 rotatably connected to the right side of the pressing block 506 through a bearing, two side blocks 508 respectively fixed to the front and back of the sliding block 503, a mounting block 509 fixed to the bottom of the side block 508, a first spring 510 fixed to the back of the rear mounting block 509, a stretching plate 511 fixed to the back of the first spring 510, a plugging block 512 fixed to the front of the stretching plate 511, a plurality of plugging grooves 513 opened on the back of the fixing plate 2 for the plugging block 512 to be plugged into, and a feel component installed inside the front mounting block 509 for the operator to clearly judge.

[0027] It should be noted that the sliding block 503 is slidably connected to the inside of the sliding groove 501, enabling the sliding block 503 to slide between the inside of the sliding groove 501 and the outside of the sliding rod 502. An internal threaded hole for the threaded connection of the threaded rod 507 is opened on the left side of the adjusting block 504, enabling the threaded rod 507 to be threadedly connected to the adjusting block 504 through the internal threaded hole. A cross-shaped handle is fixedly connected to the end of the threaded rod 507, and the cross-shaped handle is located below the positioning rod 505 for convenient rotation control. Among them, the lead angle of the threaded rod 507 is less than 20 degrees, so that the self-locking effect of the thread is relatively good and can be used for fixing and locking.

[0028] In addition, the front surface of the insertion block 512 sequentially penetrates through the inner side of the first spring 510 and the back surface of the back mounting block 509 and is inserted into the inner side of the corresponding insertion slot 513, so that the insertion block 512 can be normally inserted into the inner side of the corresponding insertion slot 513, and can correspond to the insertion and cooperation effect between the arc block 518 and the arc slot 519, which is convenient for the operator to judge.

[0029] In this embodiment, the feel component is a structure for facilitating clear judgment of the positioning node during the coarse adjustment process.

[0030] Such as Figure 3 and Figure 4 As shown, the feel component includes a connection groove 514 opened on the front surface of the front mounting block 509, a disassembly and assembly plate 515 connected to the front surface of the front mounting block 509 by screws and located on the outer side of the front of the connection groove 514, a second spring 516 fixed to the back surface of the disassembly and assembly plate 515, a square plate 517 fixed to the other side of the second spring 516, an arc block 518 fixed to the side of the square plate 517 close to the fixed plate 2, and a plurality of arc grooves 519 opened on the front surface of the fixed plate 2 for the arc block 518 to be inserted into.

[0031] It should be noted that the second spring 516 is located inside the connection groove 514, and the outer side of the square plate 517 is slidably connected to the inner side of the connection groove 514, so that the square plate 517 can stably slide inside the connection groove 514 and can drive the second spring 516 to undergo stable compressive deformation.

[0032] At the same time, the end of the arc block 518 penetrates through the side of the front mounting block 509 close to the fixed plate 2, so that the end of the arc block 518 can be normally inserted into the inner side of the arc groove 519. Among them, the part of the arc block 518 located inside the arc groove 519 does not exceed one-third of the thickness of the arc block 518, so that the arc block 518 can be inserted into the inside of the arc groove 519 during the sliding process, and can apply a small resistance to the operator for feel judgment, and at the same time does not affect the normal progress of the sliding action of the sliding block 503.

[0033] In addition, a plurality of arc grooves 519 are arranged at equal intervals on the front surface of the fixed plate 2. The number of arc grooves 519 is equal to the number of insertion slots 513, and the positions of the arc grooves 519 correspond to the positions of the insertion slots 513 one by one, so that the arc grooves 519 and the insertion slots 513 can be simultaneously inserted by the arc block 518 and the insertion block 512.

[0034] The working principle of the above embodiment is as follows:

[0035] When performing the positioning work, place the metal part on the top of the fixing plate 2, and make the outer side of the metal part abut against the right side of the workpiece baffle 4. Pull the stretching plate 511 to stretch the first spring 510, and let the inserting block 512 fall off from the inner side of the corresponding inserting slot 513, then the sliding block 503 can be moved to move on the outer side of the sliding rod 502. During the movement, the outer side of the fixing plate 2 will push the arc-shaped block 518 to move towards the side close to the connecting slot 514, compressing the second spring 516. Under the elastic recovery effect of the second spring 516, the square plate 517 and the arc-shaped block 518 are pushed to move towards the side close to the fixing plate 2, so that when the arc-shaped block 518 is inserted into the inner side of the corresponding arc-shaped slot 519, a sound of collision between the structures will be emitted, which is convenient for the operator to make a clear judgment. At the same time, the resistance between the arc-shaped block 518 and the inner side of the arc-shaped slot 519 is also convenient for the operator to feel. Push the sliding block 503 directly to the other side of the metal part, and make the arc-shaped block 518 be inside the corresponding arc-shaped slot 519. Release the stretching plate 511, and drive the inserting block 512 to be inserted into the inner side of the corresponding inserting slot 513 under the elastic recovery effect of the first spring 510 to achieve the effect of clamping and positioning, then the rough adjustment work can be completed, and the sliding block 503 can be kept in a stable state. Rotate the threaded rod 507, and under the limiting action of the positioning rod 505, the pressing block 506 can move linearly, so that the left side of the pressing block 506 abuts against the right side of the metal part, then the positioning work of the metal part can be completed, which is convenient for the normal progress of the polishing work.

[0036] Compared with the prior art, for the positioning device for metal part polishing, through the cooperation of the fixing plate 2, the vertical plate 3, the workpiece baffle 4 and the positioning mechanism 500 on the top of the working panel 1, it is convenient to perform stable positioning after rough adjustment and also convenient for the operator to judge the position points, so that the structure after rough adjustment can be kept in a stable state, reducing the possibility of deviation. At the same time, it is also convenient for the operator to visually judge the position points of the rough adjustment, facilitating the adjustment operation, thus greatly improving the practicability of the positioning device for metal part polishing, and solving the problems that the limiting structure of the existing fixture for clamping the metal block for polishing is still in a movable state after rough adjustment, there is a possibility of deviation, and it is not convenient to judge the position of the rough adjustment.
