Description

Technical Field

[0001] This utility model relates to the field of handle processing technology, specifically to a door and window handle processing fixture. Background Technology

[0002] A handle is a device installed on door and window sashes that serves both to open and close the door / window and to secure it to the frame. When the door / window is closed, the handle, along with other accessories, firmly locks the open door / window sash to the fixed frame, thus fixing the relative positions of the inner and outer frames. Handles are often made of materials such as aluminum alloy, copper, stainless steel, plexiglass, and plastic. They come in various forms and sizes.

[0003] A search revealed a Chinese patent with publication number CN218694633U, which discloses a handle tapping fixture. The fixture engages the handle with a chuck, positioning one end of the handle below the tapping drill bit. After tapping, the chuck is rotated 180 degrees, positioning the other end of the handle below the drill bit for another tapping operation. The chuck position is adjusted, and a pin is inserted into the pin hole for positioning and fixation, preventing the chuck from shaking or shifting during operation. This effectively positions and clamps the handle component, facilitating subsequent tapping operations and eliminating the need for double positioning, thus improving processing efficiency.

[0004] Although the above solution uses a rotatable fixture to facilitate the processing of both ends of the handle inside the fixture, it only relies on the clamp to fix the handle, which limits the handle to be processed. It can only fix handles of a single size, and its applicability is relatively small.

[0005] Therefore, this utility model provides a door and window handle processing fixture to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a door and window handle processing fixture to solve the problem that the above-mentioned rotatable fixture can facilitate the processing of both ends of the handle inside the fixture. However, the handle is fixed by only the clamp, which limits the handle to be processed. It can only fix handles of a single size, and the scope of application is small.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A door and window handle processing fixture includes a base and a handle body. A rotating shaft is rotatably connected to the base, and a placement platform is fixedly connected to the rotating shaft. The placement platform has a first sliding groove and a second sliding groove, which are perpendicular to each other. A first clamping component is disposed in the first sliding groove, and a second clamping component is disposed in the second sliding groove. The handle body is fixed by the first clamping component and the second clamping component. Two positioning holes are provided on the bottom surface of the placement platform. Two third sliding grooves are provided in the base. Positioning pins are slidably connected to both third sliding grooves, and the top of the positioning pins passes through the third sliding grooves and extends to the top of the base. An adjustment component is provided on the base for adjusting the extension length of the positioning pins, and the placement platform is limited by the positioning pins being inserted into the positioning holes.

[0009] Preferably, the first clamping assembly includes a first bidirectional lead screw rotatably connected to the placement platform. One end of the first bidirectional lead screw passes through the placement platform and extends to the outside of the placement platform. Two sliders are threaded onto the first bidirectional lead screw. A first clamping block is fixedly connected to each of the two sliders. One end of the first clamping block passes through the first slide groove and extends to the top of the placement platform. The first clamping block is slidably connected to the first slide groove.

[0010] Preferably, the second clamping assembly includes a second bidirectional lead screw rotatably connected to the placement platform, one end of which passes through the placement platform and extends to the outside of the placement platform. Two second clamping plates are threaded onto the second bidirectional lead screw. The top ends of the second clamping plates pass through the second slide groove and extend to the outside of the placement platform. The second clamping plates are slidably connected to the second slide groove.

[0011] Preferably, the adjusting component includes a linkage plate slidably connected within the third slide groove, and the bottom end of the positioning pin is fixedly connected to the linkage plate.

[0012] Preferably, the adjustment component includes a support fixedly connected to the base, a push-pull rod slidably connected to the support, and one end of the push-pull rod passing through the upper surface of the third slide groove and fixedly connected to the linkage plate.

[0013] Preferably, a guide rod is fixedly connected inside the third groove, and the linkage plate is slidably connected to the guide rod.

[0014] Preferably, a limiting block is fixedly connected to the push-pull rod, and a spring is sleeved on the push-pull rod, with the two ends of the spring abutting against the support and the limiting block, respectively.

[0015] Preferably, the base has mounting holes.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. Through the dual clamping of the first clamping component and the second clamping component, the fixture can firmly fix the handle body. Especially when processing the handle bend, it avoids the phenomenon of one end lifting due to uneven force. Through the cooperation of the positioning pin and the adjustment component, it ensures the precise positioning of the placement table after rotation, and prevents processing errors caused by the jig shaking or offset during the processing, thereby improving the stability and accuracy of processing.

[0018] 2. The extension length of the positioning pin can be easily adjusted by the cooperation of the push-pull rod and the spring, and the stability of the positioning pin after it is inserted into the positioning hole can be ensured. This not only simplifies the operation steps, but also reduces the trouble of frequently adjusting the fixture during the processing. Attached Figure Description

[0024] The following will refer to the attached reference. Figures 1 to 4 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0025] A door and window handle processing fixture, as shown in the attached document. Figures 1 to 4As shown, it includes a base 1 and a handle body 4. The base 1 has a mounting hole 21. The base 1 can be positioned and mounted on the processing platform by relying on the mounting hole 21. A rotating shaft 2 is rotatably connected to the base 1. A placement platform 3 is fixedly connected to the rotating shaft 2. The placement platform 3 can rotate on the rotating shaft 2. A first sliding groove 5 and a second sliding groove 11 are provided on the placement platform 3, and the first sliding groove 5 and the second sliding groove 11 are arranged perpendicular to each other.

[0026] The first sliding groove 5 is provided with a first clamping assembly. The first clamping assembly includes a first bidirectional lead screw 7 rotatably connected to the placement platform 3. One end of the first bidirectional lead screw 7 passes through the placement platform 3 and extends to the outside of the placement platform 3. Two sliders 8 are threadedly connected to the first bidirectional lead screw 7. A first clamping block 6 is fixedly connected to each of the two sliders 8. One end of the first clamping block 6 passes through the first sliding groove 5 and extends to the top of the placement platform 3. The first clamping block 6 is slidably connected to the first sliding groove 5.

[0027] In this embodiment, the first bidirectional lead screw 7 is a rod with opposite threads at both ends. When clamping and fixing the handle body 4, the first bidirectional lead screw 7 rotates, causing the two sliders 8 to move closer to each other on the first bidirectional lead screw 7, and causing the sliders 8 to drive the first clamping block 6 to slide in the first groove 5, thereby pressing the first clamping block 6 against the handle body 4, thereby clamping, fixing and positioning the middle part of the handle body 4.

[0028] The second groove 11 is provided with a second clamping assembly, and the handle body 4 is fixed by the first clamping assembly and the second clamping assembly. The second clamping assembly includes a second bidirectional lead screw 9 rotatably connected to the placement platform 3. One end of the second bidirectional lead screw 9 passes through the placement platform 3 and extends to the outside of the placement platform 3. Two second clamping plates 10 are threadedly connected to the second bidirectional lead screw 9. The top end of the second clamping plate 10 passes through the second groove 11 and extends to the outside of the placement platform 3. The second clamping plate 10 is slidably connected to the second groove 11.

[0029] In this embodiment, the second bidirectional lead screw 9 is a rod with opposite threads at both ends. After the handle body 4 is positioned, the second bidirectional lead screw 9 is rotated to make the second clamping plate 10 slide in the second slide groove 11, and the two second clamping plates 10 are respectively abutted against the two ends of the handle body 4, which can further reinforce the handle body 4 and prevent one end from lifting up when the handle body 4 is bent, thus ensuring the stability of the handle body 4 during the processing.

[0030] The bottom surface of the placement platform 3 has two positioning holes 12, and the base 1 has two third slide grooves 14. Each of the two third slide grooves 14 is slidably connected with a positioning pin 13, and the top of the positioning pin 13 passes through the third slide groove 14 and extends to the top of the base 1. The base 1 is provided with an adjustment component for adjusting the extension length of the positioning pin 13, and the placement platform 3 is limited by inserting the positioning pin 13 into the positioning hole 12.

[0031] Since the placement platform 3 can rotate on the base 1 via the rotating shaft 2, after the handle body 4 is in position on the base 1, the positioning pin 13 can be pulled out from the positioning hole 12 to release the limitation on the placement platform 3. After the placement platform 3 is rotated 180 degrees, the positioning pin 13 is then inserted into the positioning hole 12 to complete the limitation on the placement platform 3.

[0032] The adjustment component includes a linkage plate 15 slidably connected to the third slide groove 14, a positioning pin 13 fixedly connected to the bottom end of the linkage plate 15, a guide rod 16 fixedly connected to the third slide groove 14, the linkage plate 15 slidably connected to the guide rod 16, the guide rod 16 guides the linkage plate 15 to ensure the stability of the movement of the linkage plate 15, and the linkage plate 15 can drive the positioning pin 13 to move synchronously.

[0033] Furthermore, the adjustment assembly includes a support 17 fixedly connected to the base 1, and a push-pull rod 18 slidably connected to the support 17. One end of the push-pull rod 18 passes through the upper surface of the third slide groove 14 and is fixedly connected to the linkage plate 15. The push-pull rod 18 can be slid on the support 17 to drive the linkage plate 15 to move synchronously.

[0034] A limit block 19 is fixedly connected to the push-pull rod 18, and a spring 20 is sleeved on the push-pull rod 18. The two ends of the spring 20 abut against the support 17 and the limit block 19 respectively. The limit block 19 is supported by the elasticity of the spring 20 itself, which can ensure the stability of the positioning pin 13 inserted into the positioning hole 12.
