Description

Technical Field

[0001] This utility model relates to the field of metalworking fixtures, specifically a metal processing fixture. Background Technology

[0002] Fixtures are a broad category of tools used in woodworking, metalworking, and other handicrafts. They are primarily used to assist in controlling position or movement (or both). Fixtures are specialized tools used in mass production to hold products in place for processing (assembly) and to inspect product quality.

[0003] For example, a metalworking fixture with announcement number "CN213858189U" features a main body plate that effectively supports and holds the workpiece during processing. Two sets of movable plates effectively limit the lateral movement of the workpiece on the main body plate. Two sets of sliding plates also effectively clamp and limit the workpiece's movement forward and backward. A sliding rod and adjusting groove allow for effective adjustment of the sliding plate's position, accommodating different sizes of metal workpieces. A clamping device effectively limits the sliding rod's end as it moves within the adjusting groove, preventing it from detaching. However, this metalworking fixture can only process sheet metal, not cylindrical workpieces, thus limiting its functionality. Furthermore, the operator needs to manually adjust the positions of the two movable plates, which requires significant physical effort when processing a large number of workpieces, increasing the labor load. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the movable plate can only process sheet metal and cannot process cylindrical metal workpieces, thus increasing the limitation of work. At the same time, the metal processing fixture requires the operator to manually adjust the position of the two movable plates. When there are many workpieces to be processed, it requires a lot of physical strength from the operator, thus increasing the manual labor problem. Therefore, a metal processing fixture is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a metal processing fixture, including a base plate and a box body. The box body is provided on the top of the base plate. A limiting mechanism is provided inside the box body. A fixing mechanism is provided on the top of the box body. Multiple support blocks are fixedly connected to the lower end of the box body. The lower ends of the support blocks are all fixedly connected to the base plate. A collection box is placed on the upper end of the base plate. Two material collection plates are fixedly connected inside the box body.

[0007] Preferably, the limiting mechanism includes a motor, with a rotating rod fixedly connected to the end of the motor output shaft. The teeth machined on the rotating rod mesh with the tooth grooves machined on the worm gear. The teeth machined on both sides of the rotating rod are in opposite directions. The lower end of the worm gear drive shaft is rotatably connected to the housing via bearings. The upper end of the worm gear drive shaft is fixedly connected to a cam. The outer wall of the cam is in contact with a moving plate. The inner wall of the moving plate is slidably connected to a fixed column. Both ends of the fixed column are fixedly connected to the housing. A stop block is fixedly connected to the outer wall of the fixed column. Springs are provided on both sides of the stop block. The two ends of the springs are fixedly connected to the stop block and the moving plate, respectively.

[0008] Preferably, the worm gear drive shaft is rotatably connected to the front collecting plate via a sealed bearing, and the outer wall of the moving plate is slidably connected to the box body.

[0009] Preferably, the fixing mechanism includes a clamping block and bolts. Multiple locking blocks are fixedly connected to the outer side of each clamping block. Each locking block is slidably connected to the moving plate through a locking groove. The bolts are threadedly connected to the moving plate and the locking blocks respectively.

[0010] Preferably, each of the movable plates is machined with multiple slots.

[0011] The metal processing fixture proposed in this utility model has the following advantages: By cooperating with the moving plate and the fixing mechanism, the clamping block is inserted into the moving plate along the slot. Then, the operator rotates multiple bolts so that the ends of the bolts are screwed into the moving plate and the clamping block respectively, fixing the clamping block on the moving plate. This allows for the processing of cylindrical metal workpieces through the clamping block and the slot. If only block-shaped metal workpieces need to be clamped, there is no need to install the corresponding clamping block. During the inward movement of the two moving plates, the workpiece is clamped through the outer wall plane of the end of the moving plate. This achieves multiple clamping methods for block-shaped and cylindrical workpieces, thereby reducing work limitations.

[0012] By cooperating with the housing and the limiting mechanism, the rotation of the motor output shaft drives the rotating rod to rotate, which in turn drives the worm gear to rotate. The rotation of the worm gear drives the cam, which in turn drives the moving plate. This allows the operator to limit the metal workpieces without having to expend much physical effort when there are many metal workpieces to be processed, thus saving manual labor.

A limiting mechanism 2 is located inside the housing 4. A fixing mechanism 3 is located above the housing 4. Multiple support blocks 5 are fixedly connected to the lower end of the housing 4. The lower ends of the support blocks 5 are all fixedly connected to the base plate 1. A collection box 6 is placed on the upper end of the base plate 1.

The outer wall of the moving plate 205 is slidably connected to the housing 4. Multiple slots 304 are machined on the moving plate 205.

[0022] See attached document Figure 2-4

[0023] The limiting mechanism 2 includes a motor 201. The model of the motor 201 is selected according to actual needs to meet the working requirements. A rotating rod 202 is fixedly connected to the end of the output shaft of the motor 201. The teeth machined on the rotating rod 202 mesh with the tooth grooves machined on the worm gear 203. The teeth machined on both sides of the rotating rod 202 are in opposite directions. The lower end of the transmission shaft of the worm gear 203 is rotatably connected to the housing 4 through bearings. A cam 204 is fixedly connected to the upper end of the transmission shaft of the worm gear 203. The outer wall of the cam 204 is in contact with the moving plate 205. The inner wall of the moving plate 205 is... All are slidably connected to the fixed column 208. Both ends of the fixed column 208 are fixedly connected to the housing 4. The outer wall of the fixed column 208 is fixedly connected to the stop block 206. Both sides of the stop block 206 are provided with springs 207. The spring force coefficient of the spring 207 is selected according to the actual needs to meet the working requirements. Both ends of the spring 207 are fixedly connected to the stop block 206 and the moving plate 205 respectively. The output shaft of the motor 201 rotates, which drives the rotating rod 202 to rotate, thereby driving the worm gear 203 to rotate. The rotation of the worm gear 203 drives the cam 204, thereby driving the moving plate 205.

[0024] See attached document Figure 2 and attached Figure 5-6

[0025] The fixing mechanism 3 includes a clamping block 301 and a bolt 303. Multiple locking blocks 302 are fixedly connected to the outer side of the clamping block 301. The shape of the clamping block 301 can be changed according to the actual situation. The locking blocks 302 are slidably connected to the moving plate 205 through the locking groove 304. The bolt 303 is threadedly connected to the moving plate 205 and the locking blocks 302 respectively.

[0026] Working principle:

[0027] When machining metal workpieces using jigs:

[0028] Preparation process:

[0029] First, the operator can insert the clamping block 302 into the moving plate 205 along the clamping groove 304 as needed. Then, the operator rotates multiple bolts 303 so that the ends of the bolts 303 are screwed into the moving plate 205 and the clamping block 302 respectively, fixing the clamping block 301 on the moving plate 205. As the moving plates 205 on both sides move inward, cylindrical metal workpieces can be clamped through the clamping block and the clamping groove 304. If only block-shaped metal workpieces need to be clamped, the corresponding clamping block 301 does not need to be installed. As the moving plates 205 on both sides move inward, the workpiece is clamped through the outer wall plane of the end of the moving plate 205, thus realizing multiple clamping methods for block-shaped and cylindrical workpieces, thereby reducing the limitations of the work.

[0030] Metal workpiece limiting process:

[0031] The operator starts motor 201. The output shaft of motor 201 rotates forward, driving the rotating rod 202 to rotate, which in turn drives the worm gear 203 to rotate. The rotation of worm gear 203 drives cam 204, which in turn drives moving plate 205 to move inward synchronously. Spring 207 keeps moving plate 205 pressed against cam 204. The synchronous inward movement of moving plate 205 drives clamping block 301 to move inward synchronously. When the inner side of clamping block 301 is pressed against the metal workpiece, the power of motor 201 is turned off. Then the operator processes the metal workpiece. Waste chips from processing enter the collection box 6 through collection plate 7. After the metal workpiece is drilled on the equipment, the operator turns on motor 201 to reset the two clamping blocks 301. Then the operator can take out the processed metal workpiece.

[0032] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
