Abstract
Description
Technical Field
[0001] This utility model relates to the field of handle processing fixtures, and more particularly to a handle processing fixture. Background Technology
[0002] Handle machining fixtures are tools used to fix and support handle workpieces during machining, ensuring machining accuracy and stability. They are typically designed based on the handle's shape, size, and machining requirements to provide efficient and safe clamping during machining. The type, structure, materials, and working principle of handle machining fixtures may vary depending on the machining method (such as turning, milling, drilling, etc.).
[0003] Existing technologies, such as the utility model patent with publication number CN209407941U, disclose a positioning fixture for machining handle-type parts. This patent comprises a pad, a screw, a washer, and a nut. The upper surface of the pad has a threaded connection hole and a circular groove. The position of the threaded connection hole corresponds to the handle position of the handle-type part to be machined, and the position and size of the circular groove correspond to the position and size of the protruding outer circle at the front end of the rocker arm of the handle-type part. The screw and the washer are engaged in the threaded connection hole on the upper surface of the pad. The through hole at the handle of the handle-type part can be fitted onto the screw, and the protruding outer circle at the front end of the rocker arm is located within the circular groove of the pad. The upper part of the screw engages with the nut to fix the handle-type part to the pad. This utility model uses the screw and the pad (with groove) to vertically position the part in the fixture, facilitating a stable positioning state during part machining. The part is reliably clamped, reducing damage to the part during machine tool clamping and significantly improving work efficiency.
[0004] The inventors discovered in daily use that existing fixtures are typically designed for specific handle models or sizes, and cannot accommodate other handle models or sizes. This means that each time a handle is changed, the fixture needs to be redesigned or adjusted, increasing workload and time costs. Moreover, if a production line needs to process multiple handle models, using fixed fixtures leads to a lack of flexibility in the production process, requiring more frequent equipment adjustments or fixture changes, reducing production efficiency. Furthermore, different handles have different clamping methods, and fixtures cannot perfectly adapt to various handle models, resulting in inaccurate positioning or errors during processing, affecting processing accuracy and product quality.

[0021] This invention provides a clamping fixture for handle processing. By setting up a clamping structure, it addresses the limitations of existing fixtures, which are typically designed for specific handle models or sizes and cannot adapt to other handle models or sizes.

Moreover, different handles require different clamping methods, and fixtures cannot perfectly adapt to various handle models, leading to inaccurate positioning or errors during processing, affecting processing accuracy and product quality. This device achieves convenient clamping of handles of any shape, avoiding the need to change different fixtures when processing different handles. Attached Figure Description

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0030] Please see Figures 1 to 5 The present invention provides a handle processing fixture, comprising: a frame 1, wherein the frame 1 is provided with a clamping structure 2 inside.
[0031] In the embodiments of this utility model, please refer to Figures 1 to 5The clamping structure 2 includes two slide rails 201, which are fixedly connected to the frame 1. Two sliders 211 are slidably connected to the inner wall of each slide rail 201. A support rod 202 is fixedly connected to the upper surface of each slider 211. A clamping frame 203 is fixedly connected to the upper end of the support rod 202. A screw 204 is rotatably connected inside the frame 1. Opposite threads are formed on the arc surfaces at both ends of the screw 204. A connecting plate 206 is fixedly connected to one end of the screw 204. A clamping frame 203 is rotatably connected to the inner wall of the lower end of the connecting plate 206. Both ends of the rotating rod 207 and the screw 204 are threaded with threaded rings 210. The arc surfaces of the threaded rings 210 are fixedly connected to two connecting rods 209. The two connecting rods 209 are fixedly connected to two support rods 202 respectively. Several connecting frames 216 are fixedly connected inside the clamping frame 203. The inner wall of the connecting frame 216 is slidably connected to the top rod 213. A spring 215 is set inside the connecting frame 216. The two ends of the spring 215 are fixedly connected to the top rod 213 and the connecting frame 216 respectively. When clamping and processing of an item is required, the item is placed between two clamping frames 203. Then, the rotating rod 207 is rotated to move it. The rotating rod 207 drives the connecting plate 206 to move, the connecting plate 206 drives the screw 204 to rotate, the screw 204 drives the threaded ring 210 to move, the threaded ring 210 drives the connecting rod 209 to move, the connecting rod 209 drives the support rod 202 to move, and the support rod 202 drives the slider 211 to move. The slider 211 moves along the slide rail. The inner wall of 201 slides, and the support rod 202 drives the clamping frame 203 to move. Then, the clamping frame 203 drives the connecting frame 216 and the top rod 213 to move. The top rod 213 then holds the item against it and slides on the inner wall of the connecting frame 216. The top rod 213 drives the spring 215 to contract. The rebound force of the spring 215 can increase the force of the top rod 213 in pushing the item. A rubber head 214 is fixedly connected to the end of the top rod 213 away from the connecting frame 216. The rubber head 214 can increase the friction between the top rod 213 and the clamped item, preventing the top rod 213 from sliding when positioning the clamped item. A slide rod 205 is fixedly connected inside the connecting frame 216. The slide rod 205 is slidably connected to the top rod 213, and the spring 215 is sleeved on the arc surface of the slide rod 205. The slide bar 205 can limit the spring 215, preventing deformation during use and improving its service life. An anti-slip sleeve 208, made of rubber, is fixedly connected to the arc surface of the rotating rod 207. The anti-slip sleeve 208 increases friction between the hand and the rotating rod 207, preventing slippage during rotation. A limit rod 212 is fixedly connected inside the slide rail 201, slidably connected to the slider 211. The limit rod 212 limits the slider 211, preventing it from shifting when sliding on the inner wall of the slide rail 201. The support rod 202 has a rectangular cross-section and is made of stainless steel.The stainless steel material increases the service life of the support rod 202 and prevents excessive corrosion during use.

The plastic material reduces the manufacturing cost of the connecting frames 216 and also prevents them from corroding during use.
[0032] The working principle of the handle processing fixture provided by this utility model is as follows: When it is necessary to clamp and process an item, the item is placed between two clamping frames 203. Then, the rotating rod 207 is rotated to move it. The rotating rod 207 drives the connecting plate 206 to move. The connecting plate 206 drives the screw 204 to rotate. The screw 204 drives the threaded ring 210 to move. The threaded ring 210 drives the connecting rod 209 to move. The connecting rod 209 drives the support rod 202 to move. The support rod 202 drives the slider 211 to move. The slider 211 slides on the inner wall of the slide rail 201. The support rod 202 drives the clamping frame 203 to move. Then, the clamping frame 203 drives the connecting frame 216 and the top rod 213 to move. Then, the top rod 213 abuts against the item. The top rod 213 slides on the inner wall of the connecting frame 216. The top rod 213 drives the spring 215 to contract. The rebound force of spring 215 increases the force with which push rod 213 pushes the object. Rubber head 214 increases the friction between push rod 213 and the clamped object, preventing slippage when push rod 213 positions the clamped object. Slide rod 205 limits spring 215, preventing deformation during use and extending its service life. Anti-slip sleeve 208 increases friction between hand and rotating rod 207, preventing slippage when rotating rod 207. Limiting rod 212 limits slider 211, preventing it from shifting when sliding on the inner wall of slide rail 201. Stainless steel increases the service life of support rod 202 and prevents excessive corrosion during use. Plastic material reduces manufacturing cost of connecting frame 216 and prevents corrosion during use.
