Description

Technical Field

[0001] This utility model belongs to the field of parts processing technology, specifically relating to a precision parts turnover tooling. Background Technology

[0002] When handling precision cylindrical hollow metal parts, a turntable is used directly. The end face of the upper part is in direct contact with the bottom of the upper turntable. Collisions and friction are inevitable during the turntable process, which can cause wear on the end face of the parts. Since a large number of parts are transferred each time, there are many layers of turntables. The bottom part is subjected to greater force and its end face is more severely damaged. The turntable process relies entirely on the technician's skilled operation. If the technician is not careful, the parts can easily fall apart, affecting subsequent production.

[0003] According to patent number CN202322562760.9, a precision parts turnover fixture includes an outer frame, a support frame is fixedly connected inside the outer frame, and sleeves are fixedly connected to the four corners of the support frame. The sleeves are fixedly connected to the outer frame, and a through hole is opened in the middle of the sleeve.

[0004] The above solution has certain technical defects in actual use. Because the diameter of the sleeve rod cannot be adjusted according to the diameter of the precision metal part, the part cannot be accurately matched when it is sleeved on the sleeve rod. This causes the part to wobble during turnover, resulting in friction between the sleeve rod and the inner wall of the part, causing scratches on the inner wall of the part. In addition, the threaded rods and threaded holes at both ends of the support rod are fixedly connected to the support rod, which means that when installing the outer frame using the two ends of the support rod, they can only rotate simultaneously, which is difficult to operate and not conducive to the rapid installation between the two outer frames. Therefore, we propose a precision parts turnover fixture. Utility Model Content

[0005] The purpose of this invention is to provide a precision parts handling fixture to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision parts turnover fixture, comprising a turnover basket, sleeve rods, and a top block. Multiple sleeve rods are equidistantly arranged inside the turnover basket. The bottom of each sleeve rod is fixedly connected to the inner bottom surface of the turnover basket. Shrinkage grooves are fixedly formed around the outer perimeter of each sleeve rod. A top block is slidably arranged inside the shrinkage groove. Ejection springs are provided at the top and bottom of one side of the top block extending into the shrinkage groove. The two ends of the ejection springs are fixedly connected to the inner wall of the shrinkage groove and one side of the top block, respectively. An arc-shaped inclined surface is formed at the top of the side of the top block extending outside the shrinkage groove. A rubber sleeve is fixedly installed on the surface of the side of the top block extending outside the shrinkage groove, and the rubber sleeve is fixedly attached to the outer side of the top block by adhesive bonding.

[0007] Preferably, threaded sleeves are fixedly installed around the top and bottom of the turnover basket, and a lower screw and an upper screw are respectively provided between two adjacent turnover baskets. The upper screw and the lower screw are threadedly connected to the threaded sleeves at the bottom and top of the upper and lower turnover baskets, respectively. The upper screw and the lower screw are movably connected by bearings.

[0008] Preferably, the top and bottom surfaces of the shrinkage groove are provided with limiting grooves, and the top block extends to one side of the shrinkage groove and the top and bottom of the top block are fixedly installed with limiting blocks, which extend into the interior of the limiting groove and are slidably connected to its inner wall.

[0009] Preferably, a bottom pad is provided on the outer periphery of the bottom end of the sleeve rod. The bottom pad has a circular structure and is fixedly sleeved on the outer periphery of the sleeve rod and fixedly connected to the bottom of the turnover basket by adhesive bonding. The bottom pad is made of rubber.

[0010] Preferably, the inner walls of the turnover basket are all provided with rubber pads, and the rubber pads are fixed to the inner walls of the turnover basket by adhesive bonding.

[0011] Preferably, the top end of the sleeve is provided with a chamfer, and the chamfer is formed around the top end of the sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By opening a contraction groove on the outer periphery of the sleeve rod and setting a sliding top block inside the contraction groove, and using an ejector spring to push the top block outward, when the part is put on the sleeve rod, the ejector spring can provide the potential energy for the top block to extend outward, thereby pressing the part against the outer periphery of the sleeve rod. This improves the stability of the part during the turnover process and avoids shaking. The rubber sleeve contacts the inner wall of the part, preventing the inner wall of the part from directly contacting the top block and causing scratches.

[0014] 2. By using bearings to connect the upper and lower screws, the upper and lower screws can be rotated separately when stacking the two turnover baskets. This avoids the inconvenience caused by the upper and lower screws rotating synchronously during operation, greatly improving the convenience of operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a precision parts turnover tooling solution: including a turnover basket 1, sleeve rods 7, and a top block 12. Multiple sleeve rods 7 are equidistantly arranged inside the turnover basket 1. The bottom of the sleeve rods 7 is fixedly connected to the inner bottom surface of the turnover basket 1. Shrinkage grooves 9 are fixedly opened around the outside of the sleeve rods 7. The top block 12 is slidably arranged inside the shrinkage groove 9. The top and bottom ends of the top block 12 extending into the shrinkage groove 9 are provided with ejector springs 10. The two ends of the ejector springs 10 are fixedly connected to the inner wall of the shrinkage groove 9 and one side of the top block 12, respectively. The top end of the top block 12 extending into the outside of the shrinkage groove 9 is provided with an arc-shaped inclined surface. A rubber sleeve 14 is fixedly installed on the surface of the top block 12 extending into the outside of the shrinkage groove 9. The rubber sleeve 14 is fixedly set on the outer side of the top block 12 by gluing.

[0021] Specifically, threaded sleeves 3 are fixedly installed around the top and bottom of the turnover basket 1. A lower screw 4 and an upper screw 5 are respectively provided between two adjacent turnover baskets 1. The upper screw 5 and the lower screw 4 are threadedly connected to the threaded sleeves 3 at the bottom and top of the upper and lower turnover baskets 1, respectively. The upper screw 5 and the lower screw 4 are movably connected through a bearing 6.

[0022] Specifically, the top and bottom surfaces of the shrinkage groove 9 are provided with limiting grooves 11. The top block 12 extends to one side of the shrinkage groove 9 and the top and bottom are fixedly installed with limiting blocks 13. The limiting blocks 13 extend into the interior of the limiting groove 11 and slide to connect with its inner wall.

[0023] Specifically, a bottom pad 15 is fitted around the bottom of the sleeve rod 7. The bottom pad 15 is a circular ring structure. The bottom pad 15 is fixedly fitted around the outer periphery of the sleeve rod 7 and is fixedly connected to the bottom of the turnover basket 1 by gluing. The bottom pad 15 is made of rubber.

[0024] Specifically, rubber pads 2 are provided on the inner walls of the turnover basket 1 around the perimeter. The rubber pads 2 are fixed to the inner walls of the turnover basket 1 by adhesive bonding.

[0025] Specifically, the top of the lever 7 is provided with a chamfer 8, which is opened around the top of the lever 7.

[0026] In this embodiment, during use, the cylindrical, tightly fitted part is placed onto the sleeve rod 7 inside the turnover basket 1. During the fitting process, the inner wall of the part presses against the arc-shaped inclined surface at the outer top of the top block 12, causing the top block 12 to gradually shrink into the shrinkage groove 9. A rubber sleeve 14 isolates the top block 12 from the inner wall of the part, preventing scratches. The compressive force of the ejector spring 10 within the shrinkage groove 9 provides the top block 12 with outward extension potential energy, causing the rubber sleeve 14 on the outer periphery of the top block 12 to support the inner wall of the part. This ensures the part is stably fitted onto the outer periphery of the sleeve rod 7, preventing the part from shaking during handling or movement, which could cause the inner wall of the part to collide with the sleeve rod 7 and result in damage. The design effectively protects the parts from scratches. When stacking two turnover baskets 1, the lower screw 4 can be inserted into the threaded sleeve 3 inside the lower turnover basket 1. By rotating the lower screw 4, the lower screw 4 is threadedly connected to the corresponding threaded sleeve 3. Then, the threaded sleeves 3 around the bottom of the upper turnover basket 1 are aligned with the top of the upper screw 5 at the top of the lower screw 4. By rotating the upper screw 5, the thread at its top is screwed into the corresponding threaded sleeve 3, thus achieving the stacking connection of the upper and lower turnover baskets 1. This design makes it easier to operate when stacking two turnover baskets 1, avoiding the situation where the upper screw 5 and the lower screw 4 rotate at the same time, which would cause inconvenience to operation.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
