AI Technical Summary
During the roller machining process, the already assembled roller body is difficult and unstable to position when machining the side holes, which affects the machining accuracy, especially when the positioning is more difficult during manual operation.
A roller horizontal hole grinding fixture is adopted, including a base, a V-groove, a positioning block, a baffle and a holding mechanism. The roller body outer wall is clamped by the inclined surface of the V-groove, and the baffle and mounting block prevent movement. The holding mechanism presses down the top surface of the roller body to position it, so as to achieve stable clamping.
This achieves stable positioning of the roller body under manual operation, avoiding shaking during processing and improving processing accuracy and stability.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of roller processing technology, specifically, a tooling for grinding horizontal holes in rollers. Background Technology
[0002] In fields such as construction and machinery manufacturing, side-hole machining of rollers is often required. When drilling holes in rollers, the roller body is prone to rotation due to its high radial freedom and its arc-shaped surface. During side-hole drilling, unstable positioning can easily cause unexpected rotation of the roller body, resulting in hole wobbling and affecting machining accuracy. This is especially true when using manually operated grinding and drilling equipment, where positioning the already assembled roller during side-hole machining is even more difficult. Utility Model Content
[0003] The purpose of this utility model is to provide a tooling for grinding the horizontal holes of rollers, so as to solve the problem of difficult and unstable positioning when machining the side holes of an assembled roller body.
[0004] To solve the above problems, the present invention adopts the following technical means:
[0005] A roller horizontal hole grinding fixture includes a base, on which a positioning block with a V-groove is mounted. The V-groove includes a bottom horizontal surface and two inclined surfaces forming a V-shape. The roller surface of the roller body abuts against the inclined surfaces. A feed hole is constructed on the base, extending upward and penetrating through the bottom horizontal surface. A baffle is mounted on one end of the positioning block at the V-groove. A pressing and positioning mechanism is mounted on the base. The pressing and positioning mechanism includes a mounting block that abuts against the positioning block and blocks the other end of the V-groove. The pressing mechanism is rotatably mounted on the mounting block and abuts against the top surface of the roller.
[0006] Preferably, the pressing mechanism includes a pressure plate rotatably mounted on the mounting block, one end of the pressure plate being located above the roller body, and the other end of the pressure plate being equipped with an adjustment locking mechanism.
[0007] Furthermore, the adjusting locking mechanism includes a top bolt threaded onto the pressure plate, the top bolt being perpendicular to the pressure plate, and the bottom end of the top bolt slidingly abutting against the top surface of the base.
[0008] Furthermore, the bottom end of the top connecting bolt has a spherical structure.
[0009] Furthermore, the positioning block is detachably connected to the base by bolts, and the mounting block is detachably connected to the base by bolts.
[0010] This utility model has the following beneficial effects during use:
[0011] The roller body is placed on the V-groove, and the two inclined surfaces of the V-groove clamp and support the outer wall of the roller body, preventing the outer edge of the roller body from wobbling during the side hole machining process. Furthermore, the baffle and mounting block prevent the roller body from moving along the axial direction during machining. A pressing mechanism mounted on the mounting block presses down and positions the top surface of the roller body, ensuring it is securely held within the V-groove. After positioning, the cutting tool can pass through the infeed hole sequentially through the base and positioning block, contacting the side wall of the roller body for machining. Thus, through multiple positioning methods, the roller body can be stably clamped and positioned even when the cutting tool is manually operated, preventing wobbling during machining.

[0021] Please refer to Figure 1 and Figure 2 As shown, a roller horizontal hole grinding fixture includes a base 1, on which a positioning block 3 with a V-groove 2 is mounted. The V-groove 2 includes a bottom horizontal surface 4 and two inclined surfaces 5 forming a V-shape. The roller surface of the roller body 6 abuts against the inclined surfaces 5. A tool inlet hole 7 is constructed on the base 1, which extends upward and penetrates through the bottom horizontal surface 4. A baffle 8 is mounted on one end of the positioning block 3 at the V-groove 2. A pressing and positioning mechanism is mounted on the base 1. The pressing and positioning mechanism includes a mounting block 9 that abuts against the positioning block 3 and blocks the other end of the V-groove 2. The pressing mechanism is rotatably mounted on the mounting block 9 and abuts against the top surface of the roller.
[0022] In this way, the roller body 6 is placed on the V-groove 2, and the two inclined surfaces 5 of the V-groove 2 clamp and support the outer wall of the roller body 6, preventing the outer edge of the roller body 6 from shaking during the side hole machining process. Furthermore, the baffle 8 and mounting block 9 prevent the roller body 6 from moving along the axial direction during machining. The pressing mechanism mounted on the mounting block 9 presses down and positions the top surface of the roller body 6, ensuring it is securely held within the V-groove 2. After positioning, the cutting tool can pass through the infeed hole 7, sequentially through the base 1 and the positioning block 3, and contact the side wall of the roller body 6 for machining. Thus, through multiple positioning methods, even when the cutting tool is manually operated, the roller body 6 can be stably clamped and positioned, preventing shaking during machining.
[0023] Furthermore, the pressing mechanism includes a pressure plate 10 rotatably mounted on the mounting block 9, one end of the pressure plate 10 being located above the roller body 6, and the other end of the pressure plate 10 being equipped with an adjustment locking mechanism.
[0024] Furthermore, the adjusting locking mechanism includes a top bolt 11 threaded onto the pressure plate 10, the top bolt 11 being perpendicular to the pressure plate 10, and the bottom end of the top bolt 11 slidingly abutting against the top surface of the base 1.
[0025] In this way, by rotating the top connecting bolt 11, the length of the section of the top connecting bolt 11 between the pressure plate 10 and the base 1 is adjusted, thereby adjusting the downward pressure of the other end of the pressure plate 10 by utilizing the contact between the top connecting bolt 11 and the top surface of the base 1. When the top connecting bolt 11 moves upward, the pressure of the pressure plate 10 on the roller body 6 is increased, and when the top connecting bolt 11 moves upward, the pressure of the pressure plate 10 on the roller body 6 is decreased.
[0026] Furthermore, in order to facilitate the movement of the sliding contact portion between the top bolt 11 and the top surface of the substrate, and to facilitate the rotation of the top bolt 11 in the top contact state, the bottom end of the top bolt 11 is constructed as a spherical structure 12.
[0027] Furthermore, to facilitate the disassembly and installation of the entire device, the positioning block 3 is detachably connected to the base 1 by bolts, and the mounting block 9 is detachably connected to the base 1 by bolts.
[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
