Description

Technical Field

[0001] This utility model belongs to the field of precision machining technology in mechanical processing, and specifically relates to an auxiliary support fixture for manual polishing. Background Technology

[0002] Hand polishing is a traditional and widely used surface treatment process that requires polishers to use manual tools such as files, polishing paste, and sandpaper to treat the surface of parts in order to improve the surface quality of the product.

[0003] In the cold forging industry, the surface quality requirements for commonly used cold extrusion die cores are often high. After machining, manual polishing is necessary to improve their surface finish and precision. These dies are mostly hollow discs, and due to their weight, polishing personnel typically need to use one hand to hold the die and find the appropriate angle before using the other hand to hold the polishing tool. Prolonged work in this environment is physically demanding, leading to fatigue and affecting the processing efficiency and accuracy of the dies. Utility Model Content

[0004] The purpose of this invention is to solve the problems of high physical exertion, low polishing efficiency, and difficulty in ensuring polishing accuracy of heavy products, such as cold extrusion die products, during manual polishing. This invention provides an auxiliary support fixture for manual polishing.

[0005] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: an auxiliary support fixture for manual polishing, including a base and a bracket. The rear end of the base and the bracket are connected by a hinge mechanism. Support arms are symmetrically connected to both sides of the bracket. The ends of the support arms are connected to corresponding limiting grooves on both sides of the base. The support arms, bracket, and base form a triangular stable structure in the working state. The fixture adjusts and locks the support angle of the polished part by the support arms being located in different limiting grooves. A support baffle is provided at the rear end of the bracket to fix and stably support the polished part. At least two rollers are provided on the bracket. The rollers are arranged along the front-rear direction of the bracket, and the surface of the part is placed tangentially to the outer cylindrical surface of the roller.

[0006] The installation direction of the support baffle is perpendicular to the side of the roller axis near the hinge structure, ensuring that the polished part will not slip during the polishing process.

[0007] The roller's shaft is connected to a fixed groove at the front end of the bracket, and the end of the shaft is locked with a nut to provide radial support and limit axial movement during the roller's movement.

[0008] There is no relative movement between the roller and the shaft core, and the shaft core can rotate within the fixed groove.

[0009] The roller is made of hard plastic, and its surface hardness is lower than that of the part being polished. It will not scratch the surface of the part being polished after contacting the surface of the roller.

[0010] The bracket has symmetrical slots on both sides. When not in use, the support arm can be stored in the slots. The frame of the bracket is slightly smaller than the frame of the base and is folded into the frame of the base body by a hinge mechanism for easy storage.

[0011] This invention designs an auxiliary support fixture for manual polishing. For heavy parts such as cold extrusion dies and battery dies, the polishing operator can use this fixture to adjust the part to a suitable position before polishing. Compared to the previous method where the polishing operator first uses one hand to hold the die to find the appropriate angle and then uses the other hand to hold the polishing tool, this significantly improves the physical exertion of the polishing operator, reduces the workload, and increases product processing efficiency. Furthermore, this design is simple in structure, easy to use and store, and has high practicality. Attached Figure Description

Specific implementation methods

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments, but the present invention is not limited to specific embodiments. Example.

[0015] Example

[0016] like Figure 1As shown, an auxiliary support fixture for manual polishing includes a base 1 and a bracket 2. The base 1 and the rear end of the bracket 2 are connected by a hinge mechanism. Support arms 22 are symmetrically connected to both sides of the bracket 2. The ends of the support arms 22 are connected to corresponding limiting grooves 11 on both sides of the base 1. The support arms 22, the bracket 2, and the base 1 form a stable triangular structure in the working state. The fixture adjusts and locks the support angle of the polished part 3 by the support arms 22 being located in different limiting grooves 11. A support baffle 26 is provided at the rear end of the bracket 2 to fix and stably support the polished part 3. At least two rollers 23 are provided on the bracket 2. The rollers 23 are arranged along the front-rear direction of the bracket 2. The surface of the polished part 3 is placed tangentially to the outer cylindrical surface of the rollers 23.

[0017] The installation direction of the support baffle 26 is perpendicular to the side of the roller axis near the hinge structure, ensuring that the polished part 3 will not slip during the polishing process.

[0018] The core 24 of the roller 23 is connected to the fixing groove 25 at the front end of the bracket 2. The end of the core 24 is locked by a nut, which provides radial support and limits axial movement of the roller 23 during its movement.

[0019] There is no relative movement between the roller 23 and the shaft core 24, and the shaft core 24 can rotate within the fixed groove 25.

[0020] The roller 23 is made of hard plastic, and its surface hardness is lower than that of the polished part 3. It will not scratch the surface of the part after contacting the surface of the roller 23.

[0021] The bracket 2 has symmetrical slots 21 on both sides. When not in use, the support arm 22 can be stored in the slots 21. The frame of the bracket 2 is slightly smaller than the frame of the base 1. It is folded and stored in the frame of the base 1 body through a hinge mechanism, which is convenient for storage.

[0022] Further explanation is needed. This invention requires first adjusting the spacing of the rollers 23 according to the size of the part to ensure stable support for the part 3. After manually adjusting the base 1 and bracket 2 to a suitable polishing angle, the part 3 to be polished is placed on the rollers 23 of the bracket 2 for polishing. Figure 3 As shown. During the polishing process, the polishing of the workpiece 3 can be achieved by adjusting the lateral movement position or rotating the polishing position of the workpiece 3. After the workpiece 3 is polished, simply retract the support arm 22 into the receiving groove 21 of the bracket, then fold the bracket 2 and place it back into the base 1. This facilitates the storage and organization of the fixture. Figure 4 As shown.

[0023] The above description, in conjunction with preferred technical solutions, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of the utility model is limited to these descriptions. For those skilled in the art, simple deductions and substitutions can be made without departing from the concept of this utility model, and all such modifications and substitutions should be considered within the scope of protection of this utility model.
