Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of guide profile grinders, and in particular relates to a guide pressure wheel punching jig for guide profile grinders. Background Art
[0002] The guide pressure wheel is a common key component of the guide grinder. It plays a guiding and supporting role through the cooperation of bearings, shafts and other components. In the guide grinder, the guide pressure wheel is mainly used to guide the movement direction of the workpiece or the grinding wheel to ensure the processing accuracy and stability. Therefore, the guide pressure wheel made of beef tendon sheet (usually referring to polyurethane PU elastomer material) is a better choice in terms of strength and durability. However, when making the guide pressure wheel with beef tendon sheet, it is necessary to punch holes on the pressure wheel. Since the beef tendon sheet has a certain viscosity and elasticity, the drill bit will slip or deviate from the predetermined trajectory during the punching process, which will cause inaccurate punching position and affect the overall accuracy and performance of the guide pressure wheel. Since it is necessary to punch holes piece by piece, and the punching process of each beef tendon sheet may vary due to different material properties, the overall punching efficiency is low. In addition, frequent replacement and adjustment of drill bits also increase operation time and cost. Summary of the invention
[0003] The purpose of the utility model is to provide a guide pressure wheel punching jig to solve the problems raised in the above background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guide pressure wheel punching jig, comprising a jig body, a base and a top cover, wherein a accommodating cavity is provided in the jig body, at least one group of through grooves are symmetrically opened on the side wall of the jig body, a column is connected to the base, the column is placed in the accommodating cavity, the lower end surface of the base is a punching table, a through hole is opened around the column on the punching table and communicates with the accommodating cavity, the top cover is connected to the jig body by threads, a handle is detachably mounted on the top cover, and an annular drill bit avoidance groove is opened in the top cover.
[0005] Preferably, an external thread is provided on the upper portion of the column, and a central screw hole is provided at the central portion of the top cover, and the central screw hole matches the external thread on the upper portion of the column.
[0006] Preferably, two groups of through holes are formed on the punching table, one group of through holes is equipped with a drill sleeve, and the other group is for backup.
[0007] Preferably, two groups of through grooves are symmetrically opened on the side wall of the fixture body.
[0008] Technical effects and advantages of the utility model:
[0009] 1. The structure of the jig is reasonably designed and easy to operate. The column on the base not only provides structural support for the jig, but also matches the central screw hole of the top cover through the external thread on its upper part, thereby realizing the upper and lower fastening of the jig, simplifying the assembly process of the jig and improving work efficiency. The accommodating cavity in the jig body is used to accommodate and fix the guide pressure wheel to be punched (such as beef tendon sheet material). This design makes the punching process more stable and controllable.
[0010] 2. Improved drilling accuracy and stability. The design of the through slot allows the position of the workpiece to be observed or adjusted during the drilling process, which helps to ensure the accuracy of the drilling position. The drilling table and through hole on the base enable the drill bit to accurately align and penetrate the workpiece, reducing the offset and shaking during the drilling process and improving the drilling accuracy. By setting a drill sleeve on the drilling table, it not only protects the through hole 7 from drill bit wear, but also further improves the stability and accuracy of the drilling. The setting of the spare through hole increases the flexibility and durability of the fixture.
[0011] 3. Improve production efficiency and reduce costs. The automated or semi-automated (depending on whether it is combined with automated punching equipment) punching process can significantly improve production efficiency and reduce manual operation time and cost. The stable structural design and precise punching control help reduce material breakage and scrap rate, thereby reducing production costs.
[0012] 4. The design of spare through holes prolongs the service life of the fixture. When a set of through holes loses high precision due to long-term use or accidental damage, there is no need to replace the entire fixture, just switch to the spare through holes to continue working.

[0018] like Figure 1 - Figure 3 A specific implementation of a guide pressure wheel punching jig of the utility model is shown: it includes a jig body 1, a base 2 and a top cover 3, wherein a accommodating cavity 4 is provided in the jig body 1, at least one group of through grooves 5 are symmetrically opened on the side wall of the jig body 1, a column 6 is connected to the base 2, the column 6 is placed in the accommodating cavity 4, the lower end surface of the base 2 is a punching table, two groups of through holes 7 that are connected to the accommodating cavity 4 are opened around the column 6 on the punching table, one group is equipped with drill sleeves and the other group is spare, the top cover 3 is connected to the jig body 1 by threads, and a handle 8 is detachably mounted on the top cover 3; an annular drill bit avoidance groove 10 is opened in the top cover 3, this design is to prevent the drill bit from being damaged or broken, and can also be used as a chip removal channel to help the chips to be discharged smoothly, an external thread is provided on the upper part of the column 6, and a central screw hole 9 is provided in the center of the top cover 3, and the central screw hole 9 matches the external thread on the upper part of the column 6.
[0019] Gently place the guide pressure wheel to be processed into the accommodating cavity 4 of the jig body 1, making sure it is firmly mounted on the column 6, rotate the top cover 3, and fasten it to the jig body 1 through a threaded connection, apply a rotational force through the handle 8 to fix the top cover 3 more firmly on the jig body 1, insert the drill bit into the through hole 7 equipped with a drill sleeve, and adjust its position to ensure that it is aligned with the punching position on the guide pressure wheel to be processed, start the punching equipment (such as a drilling machine, a handheld electric drill, etc.), and start the punching operation. During the punching process, it is necessary to maintain a stable pressure and speed to avoid damaging the guide pressure wheel or affecting the punching accuracy. If it is found that the punching accuracy of the through hole 7 equipped with a drill sleeve decreases due to wear or other reasons, it can be immediately switched to the spare through hole 7 to continue the operation, which can ensure that production is not affected and reduce downtime.
