Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a headrest tube shaving device. Background Technology

[0002] Car seat headrest tubes are used to support the headrest on the seat back. A typical car seat headrest tube consists of two straight support tubes and a U-shaped headrest support. The headrest is installed on the headrest support. The tops of the two straight support tubes are connected to the open ends of the U-shaped headrest support via bends, and the bottoms are inserted into the seat back. The two straight support tubes often have teeth punched on their bodies. These teeth are used to connect and fix the headrest to the seat back using a snap-fit ​​device to ensure a reliable connection between the headrest and the seat back.

[0003] Application No. 2024213253021 discloses a rolling groove machine for automotive seat headrest tubes. The headrest tube is placed by opening groove holes and clamping holes in the upper and lower molds. A small electric push rod drives the positioning component and cooperates with the support component to clamp and fix the headrest tube. The tool carrier drives the cutting tool to move and groove the headrest tube, thereby effectively realizing the toothing of the headrest tube and improving work efficiency.

[0004] However, in the existing technology, when inserting the headrest tube into the slotted hole and clamping hole, there is a lack of positioning of the insertion depth of the headrest tube, which cannot effectively ensure the consistency of the insertion depth of the headrest tube, and thus cannot ensure the consistency of the position of the teeth of the headrest tube, thereby affecting the quality of the headrest tube product. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a headrest tube shaving device to solve the problem of ineffective positioning of the slotted position.

[0006] To achieve the above objectives, this utility model provides a headrest tube shaving device, including a processing table, mounting frames at both ends of the processing table, a clamping mechanism at the lower side between the mounting frames at both ends for clamping and fixing the headrest tube, a shaving mechanism at the upper side between the mounting frames at both ends for shaving the clamped headrest tube, and a positioning mechanism at one side of the middle of the processing table for positioning the headrest tube.

[0007] A further improvement is that the clamping mechanism includes a fixed block fixedly mounted on one end of the mounting frame and a movable block movably mounted on the other end of the mounting frame. A clamping cylinder is fixedly mounted on the mounting frame, and the output end of the clamping cylinder is fixedly connected to the movable block.

[0008] A further improvement is that the fixed block and the movable block are respectively provided with clamping grooves on their opposite sides. The clamping grooves are adapted to the outer wall of the headrest tube and are used to stably clamp the headrest tube.

[0009] A further improvement is that the shaving mechanism includes a movable plate, with corresponding sliding openings on the mounting brackets at both ends. The two ends of the movable plate are slidably disposed in the sliding openings. A push-pull cylinder is mounted on the mounting bracket, and the output end of the push-pull cylinder is connected to one end of the movable plate. A mounting groove is provided on the lower side of the movable plate, and a cutting tool is installed in the mounting groove.

[0010] A further improvement is that the cutting tool is provided with a locking block, and a locking groove is opened on the side of the mounting slot. The locking block and the locking groove are compatible, and a bolt is threadedly connected between the locking block and the locking groove. The cutting tool is fixedly installed by the bolt.

[0011] A further improvement is that the positioning mechanism includes a positioning bracket that is bolted to the processing table, a positioning block that is fixedly mounted on the positioning bracket, and a locking block that is rotatably mounted on the positioning block via a rotating shaft.

[0012] The beneficial effects of this utility model are as follows: By setting a positioning mechanism, after the headrest tube is inserted into the clamping groove of the fixing block and the positioning bracket is attached to the surface of the positioning bracket, the locking block is rotated to lock the headrest tube between the locking block and the positioning bracket, ensuring that the headrest tube is placed in place and improving the accuracy of the shaving position. By setting a fixing block and a movable block to clamp the headrest tube in the clamping groove, the shaving mechanism shaves the part of the headrest tube extending from the clamping groove from the top, ensuring product quality and greatly improving processing efficiency.

[0018] like Figure 1-3 As shown, this embodiment provides a headrest tube shaving device, including a processing table 1. The processing table 1 has mounting brackets 2 at both ends. A clamping mechanism is provided on the lower side between the mounting brackets 2 at both ends. The headrest tube is clamped and fixed by the clamping mechanism. The clamping mechanism includes a fixed block 3 fixedly mounted on one end mounting bracket 2 and a movable block 4 movably mounted on the other end mounting bracket 2. A clamping cylinder 5 is fixedly mounted on the mounting bracket 2. The output end of the clamping cylinder 5 is fixedly connected to the movable block 4. A clamping groove 6 is opened on the opposite side of the fixed block 3 and the movable block 4. The clamping groove 6 is adapted to the outer wall of the headrest tube and is used to stably clamp the headrest tube. By placing the end of the headrest tube to be processed on the clamping groove 6 of the fixed block 3 and fitting it, the clamping cylinder 5 drives the movable block 4 to move towards the fixed block 3, so that the clamping groove 6 of the movable block 4 fits against the other side of the end of the headrest tube to be processed. The end of the headrest tube to be processed is clamped by the fixed block 3 and the movable block 4, so that the end of the headrest tube to be processed is locked in the clamping groove 6 for fixation.

[0019] like Figure 3As shown, a positioning mechanism is provided on one side of the middle of the processing table 1. The positioning mechanism is used to position the headrest tube. The positioning mechanism includes a positioning bracket 13 that is bolted to the processing table 1. The processing table 1 has multiple threaded holes. The positioning bracket 13 moves to the corresponding threaded hole for installation according to processing requirements. A positioning block 14 is fixedly installed on the positioning bracket 13. The positioning block 14 is adapted to the shape of the inner side of the bent end of the headrest tube. A locking block 15 is rotatably installed on the positioning block 14 via a rotating shaft. When placing the headrest tube, when the vertical end of the headrest tube is inserted between the fixed block 3 and the movable block 4 for clamping, the bent end of the headrest tube is attached to the positioning bracket 13, and the inner side of the headrest tube is attached to the positioning block 14. Rotating the locking block 15 limits the bending end of the headrest tube to fit tightly against the positioning bracket 13, thereby ensuring the accuracy of the headrest tube insertion position and ensuring the consistency of product quality.

[0020] like Figure 2 As shown, a shaving mechanism is provided on the upper side between the two mounting brackets 2. The shaving mechanism shaves the clamped headrest tube. The shaving mechanism includes a moving plate 7. The mounting brackets 2 at both ends are provided with sliding openings. The two ends of the moving plate 7 are slidably disposed in the sliding openings. A push-pull cylinder 8 is installed on one end of the mounting bracket 2. The output end of the push-pull cylinder 8 is connected to one end of the moving plate 7. The push-pull cylinder 8 drives the moving plate 7 to move back and forth. A mounting groove 9 is provided on the lower side of the moving plate 7. One side of the mounting groove 9 is a closed end and the other side is an open end. A cutter 10 is installed in the mounting groove 9. The cutter 10 is slidably engaged in the mounting groove 9 through the open end. The reciprocating movement of the moving plate 7 drives the cutter 10 to move and perform shaving.

[0021] The cutting tool 10 is provided with a locking block 11, and the mounting groove 9 has a locking groove 12 on one side of the open end. The locking block 11 and the locking groove 12 are compatible. The cutting tool 10 is slidably locked in the mounting groove 9, and the locking block 11 is correspondingly locked in the locking groove 12. A bolt is threaded between the locking block 11 and the locking groove 12. The bolt locks the locking block 11 in the locking groove 12, thereby fixing the cutting tool 10 in the mounting groove 9 by bolts, which facilitates the installation and removal of the cutting tool 10.

[0022] During processing, the vertical end of the headrest tube is inserted vertically into the clamping groove 6 on one side of the fixing block 3, with the vertical end of the headrest tube attached to the positioning bracket 13. The positioning block 14 limits the headrest tube from the inside. The locking block 15 is rotated to lock the headrest tube between the positioning bracket 13 and the locking block 15, ensuring the accuracy of the headrest tube insertion position. The clamping cylinder 5 pushes the movable block 4 to move and clamp the headrest tube. The moving plate 7 drives the cutting tool 10 to reciprocate for a certain period of tooth shaving. After processing, the clamping cylinder 5 drives the movable block 4 to reset and contact the clamping of the headrest tube. The locking block 15 is rotated to release the locking of the headrest tube, and the headrest tube is taken out and placed into the next headrest tube for processing.
