Description

Technical Field

[0001] This utility model relates to the field of polishing tools, specifically a polishing tool for hardware production that is easy to fix. Background Technology

[0002] Hardware refers to auxiliary and accessory manufactured products used in daily life and industrial production, made of metal materials such as gold, silver, copper, iron, and tin. With the development of economy and technology, the use of hardware products is becoming more and more widespread. During the production process, hardware needs to be polished by polishing equipment.

[0003] Application number CN202320224102.6 discloses a conveniently fixed grinding tool for hardware production, relating to the field of hardware processing technology. It includes a base, with a rotating rod rotatably connected through the middle of the base. A lead screw is fixedly connected to the bottom end of the rotating rod, and a threaded block is threadedly connected to the outer wall of the lead screw. A U-shaped support rod is fixedly connected to the front surface of the threaded block, and the U-shaped support rod and the base are fixedly connected by an elastic telescopic rod. A disc is rotatably connected to the top of the base, and a triangular limiting block is fixedly connected to the inner wall of the disc. A round rod is fixedly connected to the outer wall of the rotating rod. By stepping on a foot pedal, the U-shaped support rod moves the threaded block downwards, causing the lead screw to rotate, which in turn causes the disc to rotate a placement plate, thereby achieving the purpose of adjusting the hardware product. This method only requires stepping on a foot pedal, eliminating the need for manual operation, preventing the hardware product from shifting, increasing the stability of the grinding work, and enhancing the practicality of the device.

[0004] This structure uses a foot pedal to rotate a U-shaped support rod, which in turn rotates a threaded block and a lead screw, causing a disc to rotate a placement plate to adjust the hardware products. The entire process involves the transmission of multiple components, making the operation relatively cumbersome. The time from preparation to fixing the hardware and allowing for polishing is relatively long, resulting in low clamping efficiency. Placing the hardware products on the placement plate of the disc is mainly limited by triangular limit blocks. For hardware products with large differences in shape and size, it is difficult to achieve stable clamping through simple adjustments, resulting in poor versatility. Utility Model Content

[0005] The purpose of this invention is to provide a convenient and easy-to-fix grinding tool for hardware production, thereby solving the problem of low clamping efficiency for hardware workpieces.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a convenient and easy-to-fix grinding tool for hardware production, comprising a grinding assembly and a clamp. The clamp is installed below the grinding assembly and includes a support base. A bend plate is vertically fixedly connected to the top outer wall of the support base. A bend positioning block is provided inside the bend plate. Cylinders are fixedly installed on the bottom two inner walls of the support base away from the bend plate. Positioning blocks are fixedly connected to the top outer wall of the support base near the two sets of cylinders. A hinge rod is hinged to the output end of the cylinder. The middle part of the hinge rod is hinged to the positioning block. A pressing block is fixedly installed at the extended end of the hinge rod.

[0008] The purpose of this setting is that, during the operation of the grinding tool, depending on the shape and size of the hardware, if necessary, the position of the corner positioning block in the corner plate groove can be adjusted first so that the hardware can be initially positioned against the corner positioning block. The hardware to be ground can then be placed stably on the support base so that it fits against the corner positioning block, preparing for subsequent clamping.

[0009] When the cylinders fixedly installed on the inner walls on both sides of the bottom of the support base are activated, the power system of the cylinders starts to work, and its output end begins to extend. The cylinder output end is hinged to the hinge rod. As the cylinder output end extends, the hinge rod begins to rotate with the middle part of its hinge with the positioning block as the fulcrum.

[0010] An extrusion block is fixedly installed at the extended end of the hinge rod. During the rotation of the hinge rod, the extrusion block moves toward the hardware and gradually approaches the hardware. When the extrusion block contacts the hardware, it continues to apply pressure under the action of the cylinder to firmly clamp the hardware onto the support seat, ensuring that the hardware will not shift during subsequent grinding.

[0011] The grinding assembly is activated to perform grinding operations on the clamped hardware. During this time, the fixture maintains a clamped state on the hardware, providing stable workpiece support for the grinding process. The structure of the hinge rod and pressing block driven by the cylinder can quickly clamp the hardware onto the support base. Compared with traditional manual fixtures, this greatly shortens the clamping time and improves production efficiency.

[0012] The angled positioning block, in conjunction with the pressing block, positions and clamps the hardware from two directions, ensuring the stability of the hardware during grinding, reducing grinding accuracy deviations caused by workpiece wobbling, and improving grinding quality. This fixture structure is suitable for hardware of various shapes and sizes. By simply adjusting the position of the angled positioning block, it can accommodate workpieces of different specifications, reducing the cost for enterprises that would otherwise need to equip multiple fixtures due to the variety of workpieces.

[0013] Furthermore, sliding grooves are provided on the outer walls of both sides of the angle plate, and sliding screw one and sliding screw two are fixedly connected to the outer side of the angle positioning block respectively.

[0014] The purpose of this design is to adjust the position of the angle positioning block by sliding the first and second sliding screws on both sides of the angle positioning block within the grooves on both sides of the angle plate, according to the size of the hardware parts, during the operation of the grinding tool.

[0015] Furthermore, the first sliding screw and the second sliding screw are slidably connected in the sliding grooves on both sides of the angle plate, and the rods of the first sliding screw and the second sliding screw are threaded with nuts.

[0016] The purpose of this setup is that, during the operation of the grinding tool, after adjusting the position of the angle positioning block, the nuts on sliding screw one and sliding screw two are rotated to tighten them onto the outer wall of the angle plate, thus fixing the position of the angle positioning block.

[0017] Furthermore, a filter plate is embedded on the top inner wall of the support base, the extrusion block and the corner positioning block are located around the top of the filter plate, and a feeding hopper is fixedly connected to the outer wall of the support base directly below the filter plate, and a collection box is placed directly below the feeding hopper.

[0018] The purpose of this design is that during the operation of the grinding tool, the debris generated during grinding falls into the feed hopper below through the filter plate embedded in the inner wall of the top of the support base, and is then guided by the feed hopper into the collection box directly below for collection.

[0019] Furthermore, the grinding assembly includes an electric telescopic frame, a slide rail one is fixedly installed on the top outer wall of the electric telescopic frame, a motor one is fixedly installed on one side outer wall of the slide rail one, a bidirectional ball screw is installed on the inner wall of the slide rail one, and a slide rail two is fixedly installed on the moving block of the bidirectional ball screw.

[0020] The purpose of this setup is to control the extension and retraction of the electric telescopic frame according to the grinding requirements, adjust the overall height of the grinding assembly, start motor one, and drive the bidirectional ball screw to rotate, so that the slide rail two installed on the bidirectional ball screw moving block moves in the direction of slide rail one.

[0021] Furthermore, a bidirectional ball screw assembly is installed on the inner wall of the slide rail two, and a motor two is fixedly installed on one outer wall of the slide rail two. The output ends of the motor one and the motor two are respectively connected to one end of the bidirectional ball screw and the bidirectional ball screw assembly. A grinding machine is vertically installed on the inner wall of the bidirectional ball screw assembly, and the grinding machine is located above the support base.

[0022] The purpose of this setup is that during the operation of the grinding tool, motor two is started, which drives the bidirectional lead screw assembly to rotate, causing the grinding machine installed on the inner wall of the bidirectional lead screw assembly to move in the direction of slide rail two; the position of the grinding machine is controlled by the cooperation of motor one and motor two, and the hardware clamped on the fixture is ground.

[0023] This utility model has the following beneficial effects:

[0024] (1) This utility model uses the setting of corner positioning, cylinder and extrusion block. The corner positioning block cooperates with the extrusion block to position and clamp the hardware from two directions, thereby improving the grinding quality. The fixture structure is suitable for hardware of various shapes and sizes. By simply adjusting the position of the corner positioning block, it can adapt to the clamping of workpieces of different specifications, thereby reducing the cost of equipping multiple fixtures.

[0025] (2) This utility model, through the setting of electric telescopic frame, bidirectional ball screw and grinding machine, controls the extension and retraction of electric telescopic frame according to grinding requirements, adjusts the overall height of grinding assembly, starts motor one, motor one drives bidirectional ball screw to rotate, so that slide rail two installed on bidirectional ball screw moving block moves in the direction of slide rail one, and controls the position of grinding machine through the cooperation of motor one and motor two to grind the hardware clamped on the fixture.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0035] Please see Figures 1-4 As shown, this utility model is a convenient and easy-to-fix grinding tool for hardware production, including a grinding component 1 and a clamp 2. The clamp 2 is installed below the grinding component 1. The clamp 2 includes a support base 201. An angle plate 205 is vertically fixedly connected to the top outer wall of the support base 201. An angle positioning block 211 is provided inside the angle plate 205. Cylinders 206 are fixedly installed on the bottom two inner walls of the support base 201 away from the angle plate 205. Positioning blocks 207 are fixedly connected to the top outer wall of the support base 201 near the two sets of cylinders 206. A hinge rod 208 is hinged to the output end of the cylinder 206. The middle part of the hinge rod 208 is hinged to the positioning block 207. A pressing block 209 is fixedly installed on the extended end of the hinge rod 208.

[0036] The purpose of this setting is that, during the operation of the grinding tool, depending on the shape and size of the hardware, if necessary, the position of the corner positioning block 211 in the groove 210 of the corner plate 205 can be adjusted first, so that the hardware can be initially positioned against the corner positioning block 211, and the hardware to be ground can be placed stably on the support base 201 so that it fits against the corner positioning block 211, in preparation for subsequent clamping.

[0037] The cylinders 206, which are fixedly installed on the inner walls of both sides of the bottom of the start support 201, start working. The power system of the cylinders 206 begins to work, and its output end begins to extend. The output end of the cylinder 206 is hinged to the hinge rod 208. As the output end of the cylinder extends, the hinge rod 208 begins to rotate with the middle part of its hinge with the positioning block 207 as the fulcrum.

[0038] A pressing block 209 is fixedly installed at the extended end of the hinge rod 208. During the rotation of the hinge rod 208, the pressing block 209 moves toward the hardware and gradually approaches the hardware. When the pressing block 209 contacts the hardware, it continues to apply pressure under the action of the cylinder 206 to firmly clamp the hardware onto the support base 201, ensuring that the hardware will not be displaced during subsequent grinding.

[0039] The grinding assembly 1 is activated to perform grinding operations on the clamped hardware. At this time, the clamp 2 maintains the clamping state of the hardware, providing stable workpiece fixing support for the grinding process. Through the structure of the cylinder 206 driving the hinge rod 208 and the pressing block 209, the hardware can be quickly clamped on the support base 201. Compared with traditional manual clamps, the clamping time is greatly shortened and the production efficiency is improved.

[0040] The angle positioning block 211, in conjunction with the pressing block 209, positions and clamps the hardware from two directions, ensuring the stability of the hardware during grinding, reducing grinding accuracy deviations caused by workpiece wobbling, and improving grinding quality. This fixture structure is suitable for hardware of various shapes and sizes. By simply adjusting the position of the angle positioning block 211, it can adapt to the clamping of workpieces of different specifications, reducing the cost for enterprises that need to equip multiple fixtures due to the variety of workpieces.

[0041] The outer walls of the two sides of the angle plate 205 are provided with sliding grooves 210, and the outer sides of the angle positioning block 211 are respectively fixedly connected with sliding screw 1 212 and sliding screw 213.

[0042] The purpose of this setting is to adjust the position of the angle positioning block 211 by sliding the first sliding screw 212 and the second sliding screw 213 on both sides of the angle positioning block 211 within the grooves 210 on both sides of the angle plate 205, according to the size of the hardware parts during the operation of the grinding tool.

[0043] Sliding screw 1 212 and sliding screw 213 are slidably connected in the sliding grooves 210 on both sides of the angle plate 205, and the rods of sliding screw 1 212 and sliding screw 213 are threadedly connected with nuts 214.

[0044] The purpose of this setup is that, during the operation of the grinding tool, after adjusting the position of the angle positioning block 211, the nuts 214 on the sliding screw 1 212 and the sliding screw 213 are rotated to tighten them onto the outer wall of the angle plate 205, thus fixing the position of the angle positioning block 211.

[0045] A filter plate 202 is embedded on the top inner wall of the support base 201. The extrusion block 209 and the corner positioning block 211 are located around the top of the filter plate 202. A feeding hopper 203 is fixedly connected to the outer wall of the support base 201 directly below the filter plate 202. A collection box 204 is placed directly below the feeding hopper 203.

[0046] The purpose of this design is that during the operation of the grinding tool, the debris generated during the grinding process falls into the feed hopper 203 below through the filter plate 202 embedded in the inner wall of the top of the support base 201, and is then guided by the feed hopper 203 to the collection box 204 directly below for collection.

[0047] The grinding assembly 1 includes an electric telescopic frame 101. A slide rail 102 is fixedly installed on the top outer wall of the electric telescopic frame 101. A motor 103 is fixedly installed on one side outer wall of the slide rail 102. A bidirectional ball screw 104 is installed on the inner wall of the slide rail 102. A slide rail 2 105 is fixedly installed on the moving block of the bidirectional ball screw 104.

[0048] The purpose of this setup is to control the extension and retraction of the electric telescopic frame 101 according to the grinding requirements, adjust the overall height of the grinding assembly 1, start the motor 103, and drive the bidirectional ball screw 104 to rotate, so that the slide rail 105 installed on the moving block of the bidirectional ball screw 104 moves in the direction of the slide rail 102.

[0049] A bidirectional ball screw assembly 107 is installed on the inner wall of slide rail 2 105. A motor 2 106 is fixedly installed on one outer wall of slide rail 2 105. The output ends of motor 1 103 and motor 2 106 are respectively connected to one end of bidirectional ball screw 104 and bidirectional ball screw assembly 107. A grinder 108 is vertically installed on the inner wall of bidirectional ball screw assembly 107. The grinder 108 is located above the support base 201.

[0050] The purpose of this setup is that during the operation of the grinding tool, motor 2 106 is started, which drives the bidirectional lead screw assembly 107 to rotate, causing the grinding machine 108 installed on the inner wall of the bidirectional lead screw assembly 107 to move in the direction of slide rail 2 105; the position of the grinding machine 108 is controlled by the cooperation of motor 1 103 and motor 2 106, and the hardware clamped on the fixture 2 is ground.

[0051] When using it, first adjust the position of the angle positioning block 211 in the groove 210 of the angle plate 205 according to the size of the hardware parts by sliding screw 1 212, sliding screw 213 and nut 214, and fix the angle positioning block 211.

[0052] Place the hardware on the support base 201 and rest it against the corner positioning block 211. Activate the cylinder 206, causing the hinge rod 208 to drive the pressing block 209 to clamp the hardware onto the support base 201;

[0053] According to the grinding position requirements of the hardware parts, control the electric telescopic frame 101 to adjust the height of the grinding assembly 1. Then start motor one 103 and motor two 106 to drive the bidirectional ball screw 104 and bidirectional screw assembly 107 respectively, and adjust the position of the grinding machine 108.

[0054] The grinding machine 108 is started to grind the hardware parts. The debris generated during the grinding process falls into the collection box 204 through the filter plate 202 and the feed hopper 203.

[0055] The structure of the hinge rod 208 and the pressing block 209 driven by the cylinder 206 can quickly clamp the hardware parts onto the support base 201. Compared with traditional manual clamps, it greatly shortens the clamping time and improves production efficiency. The angle positioning block 211, together with the pressing block 209, positions and clamps the hardware parts from two directions, which can ensure the stability of the hardware parts during the grinding process.
