[0004] Prior art CN215237333U has many benefits in use, but still has the following problems, its fixed efficiency is low for frame, since it needs multi-step operation process to be fixed, so that the assembly step between frame and device is more complicated, affect the fixed efficiency of frame. UTILITY MODEL CONTENTS

[0005] In view of the problems in the prior art, the utility model provides a lifting processing device for bicycle production.

[0006] The technical solution adopted by this utility model to solve its technical problem is a lifting and processing device for bicycle production, including a processing table, a clamping top plate and a fixing frame. Hydraulic cylinders are screwed to both sides of the upper outer wall of the processing table. A clamping bottom plate is screwed to the upper outer wall of the hydraulic cylinder. A clamping top plate is provided on the outside of the clamping bottom plate. Guide rods are symmetrically and movably installed inside the clamping top plate. Wedges are provided on both sides of the lower outer wall of the clamping top plate. A fixing frame is provided on both sides of the upper outer wall of the processing table.

[0007] By adopting the above technical solution, the workers place the bottom tube of the frame on the upper part of the clamping base plate, and keep the weight of both ends of the frame equal to ensure that the frame is relatively stable in the upper part of the clamping base plate. During the upward movement of the hydraulic cylinder push rod, it can carry the clamping base plate and the frame upward synchronously, thereby realizing the purpose of lifting the frame. The position and height can be flexibly adjusted according to the processing requirements of different bicycle parts, which greatly improves the applicability of the device in different processing scenarios. As the wedge moves upward, the wedge breaks away from the obstruction of the limit rod, and under the elastic force of the return spring, it can push the clamping top plate to move horizontally outside the guide rod until the clamping top plate covers the upper part of the clamping base plate. At this time, the bottom tube of the frame is fixed between the clamping base plate and the clamping top plate, achieving the purpose of self-fixing the frame, shortening the frame fixing steps, improving the frame fixing efficiency, and facilitating the assembly of the frame by the device.

[0008] Specifically, the processing table has legs screwed to both sides of the lower outer wall. The legs are designed in an L-shape, and through holes are opened on both sides of the lower outer wall of the legs.

[0009] By adopting the above technical solution, the staff can use the external screw to pass through the through hole to fix the stand in the position of use. The L-shaped stand can provide stable support for the entire device and effectively prevent the device from shaking or shifting during operation.

[0010] Specifically, connecting bolts are movably installed on both outer walls of the clamping base plate, and the connecting bolts are threaded through the clamping base plate and connected to the inside of the guide rod.

[0011] By adopting the above technical solution, the position of the guide rod can be fixed by connecting bolts, ensuring the stability of the guide rod's position on the outside of the clamping base plate. This provides auxiliary positioning and guidance for the subsequent movement of the clamping top plate on the outside of the guide rod, ensuring the smoothness and stability of the clamping top plate's movement.

[0012] Specifically, protective pads are glued and fixed to the inner walls of both the clamping top plate and the clamping bottom plate. A baffle is screwed to one side of the upper outer wall of the clamping bottom plate, and the upper surface of the baffle is at the same level as the upper surface of the clamping top plate.

[0013] By adopting the above technical solution, the protective pad can effectively avoid damage to the surface of bicycle parts during clamping, protect the integrity and aesthetics of the frame, and the baffle, together with the clamping top plate and clamping bottom plate, can cover the outer wall of the frame, thereby fixing the frame and ensuring the stability of the position during subsequent frame processing.

[0014] Specifically, the outer wall of one side of the wedge is designed with an inclined shape, and a fastener is installed on one side of the upper outer wall of the wedge. The wedge is connected to the outer wall of the clamping top plate by screws through the fastener.

[0015] By adopting the above technical solution, the wedge block is positioned stably on the outside of the clamping top plate by fasteners, and it is easy to disassemble and maintain the wedge block.

[0016] Specifically, a limit rod is screwed to one side of the outer wall of the fixing frame, and the limit rod is in contact with the outer wall of the wedge block. Fixing components are installed at the lower ends of the outer walls on both sides of the fixing frame, and the fixing frame is connected to the upper outer wall of the processing table through the fixing components.

[0017] By adopting the above technical solution, when the wedge moves upward and is driven upward by the hydraulic cylinder, the wedge moves relative to the inclined surface and the limiting rod under the push of the return spring, thereby moving the clamping top plate to the upper end of the clamping bottom plate to fix the frame on the upper end of the clamping bottom plate. After the wedge moves downward, the inclined surface of the wedge contacts the outer wall of the limiting rod, and due to the restriction of the limiting rod, the clamping top plate is driven to move away from the clamping bottom plate, unfolding the clamping bottom plate to facilitate the workers to pick up and put down the frame. At this time, the clamping top plate compresses and stores energy in the return spring, and the fixing frame is kept stable on the upper end of the processing table by the fixing parts.

[0018] Specifically, a return spring is provided on one side of the outer wall of the guide rod, and the clamping top plate is elastically connected to the outer wall of one side of the guide rod through the return spring.

[0019] By adopting the above technical solution, when the wedge block is released from the limit rod, the reset spring releases energy and pushes the clamping top plate to move, ensuring the smooth reciprocating movement of the clamping top plate.

[0020] The beneficial effects of this utility model are:

[0021] (1) The lifting and processing device for bicycle production described in this utility model can carry the clamping base plate and the frame to move up synchronously during the upward movement of the push rod part of the hydraulic cylinder, thereby realizing the purpose of lifting and lowering the frame. The position and height can be flexibly adjusted according to the processing requirements of different bicycle parts, which greatly improves the applicability of the device in different processing scenarios.

[0022] (2) The bicycle production lifting processing device described in this utility model fixes the lower tube of the frame between the clamping bottom plate and the clamping top plate, thereby achieving the purpose of fixing the frame by itself, completing the automatic fixing of the frame, shortening the fixing steps of the frame, improving the fixing efficiency of the frame, and facilitating the assembly of the frame by the device.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the bicycle manufacturing lifting and processing device of this utility model includes a processing table 1, a clamping top plate 2, and a fixing frame 3. Hydraulic cylinders 11 are screwed to both sides of the upper outer wall of the processing table 1. A clamping bottom plate 13 is screwed to the upper outer wall of the hydraulic cylinders 11. A clamping top plate 2 is provided on the outer side of the clamping bottom plate 13. Guide rods 21 are symmetrically and movably installed inside the clamping top plate 2. Wedges 23 are provided on both sides of the lower outer wall of the clamping top plate 2. A fixing frame 3 is provided on both sides of the upper outer wall of the processing table 1.

[0031] During use, the operator places the bottom tube of the frame on the upper end of the clamping base plate 13, ensuring that the weight of both ends of the frame is equal. This ensures that the frame is relatively stable on the upper end of the clamping base plate 13. As the push rod of the hydraulic cylinder 11 moves upward, it can carry the clamping base plate 13 and the frame upward synchronously, thereby achieving the purpose of lifting and lowering the frame. The position and height can be flexibly adjusted according to the processing requirements of different bicycle parts, greatly improving the applicability of the device in different processing scenarios. As the wedge 23 moves upward, the wedge 23 is released from the obstruction of the limit rod 32. Under the elastic force of the return spring 22, the clamping top plate 2 can be pushed to move horizontally outside the guide rod 21 until the clamping top plate 2 covers the upper end of the clamping base plate 13. At this time, the bottom tube of the frame is fixed between the clamping base plate 13 and the clamping top plate 2, achieving the purpose of fixing the frame itself, shortening the frame fixing steps, improving the frame fixing efficiency, and facilitating the assembly of the frame by the device.

[0032] To fix the usage location, for example, such as Figure 1 As shown, both sides of the lower outer wall of the processing table 1 are screwed with legs 12. The legs 12 adopt an L-shaped design, and both sides of the lower outer wall of the legs 12 are provided with through holes.

[0033] When in use, the staff can use the external screw to pass through the through hole to fix the stand 12 in the position. The L-shaped stand 12 can provide stable support for the entire device and effectively prevent the device from shaking or shifting during operation.

[0034] To maintain the usage location, for example, such as Figure 3 As shown, connecting bolts 15 are movably installed on both outer walls of the clamping base plate 13. The connecting bolts 15 pass through the clamping base plate 13 and are threaded into the guide rod 21.

[0035] During use, the guide rod 21 can be fixed in position by connecting bolt 15, ensuring the stability of the guide rod 21 outside the clamping base plate 13. This provides auxiliary positioning and guidance for the subsequent movement of the clamping top plate 2 outside the guide rod 21, ensuring the smoothness and stability of the movement of the clamping top plate 2.

[0036] To protect the frame, for example, such as Figure 3 As shown, protective pads 16 are glued and fixed to the inner walls of both the clamping top plate 2 and the clamping bottom plate 13. A baffle 14 is screwed to one side of the upper outer wall of the clamping bottom plate 13. The upper surface of the baffle 14 is at the same level as the upper surface of the clamping top plate 2.

[0037] When in use, the protective pad 16 can effectively prevent damage to the surface of bicycle parts during clamping, protecting the integrity and aesthetics of the frame. The baffle 14, together with the clamping top plate 2 and clamping bottom plate 13, can cover the outer wall of the frame, thereby fixing the frame and ensuring the stability of the position during subsequent frame processing.

[0038] For example, to enable coordinated movement, such as... Figure 3 As shown, the outer wall of the wedge 23 is designed with an inclined shape, and a fastener 24 is installed on one side of the upper outer wall of the wedge 23. The wedge 23 is connected to the outer wall of the clamping top plate 2 by screws through the fastener 24.

[0039] During use, the wedge 23 is secured by fasteners 24 to ensure its stable position on the outside of the clamping top plate 2, and facilitates disassembly and maintenance of the wedge 23.

[0040] To drive movement, for example, such as Figure 4 As shown, a limit rod 32 is screwed to one side of the outer wall of the fixed frame 3. The limit rod 32 is in contact with the outer wall of the wedge block 23. Fixing parts 31 are installed at the lower ends of the outer walls on both sides of the fixed frame 3. The fixed frame 3 is connected to the upper outer wall of the processing table 1 through the fixing parts 31.

[0041] In use, when the wedge 23 moves upward following the hydraulic cylinder 11, the wedge 23, under the push of the return spring 22, will move relative to the inclined surface and the limiting rod 32, thereby moving the clamping top plate 2 to the upper end of the clamping bottom plate 13 to fix the frame at the upper end of the clamping bottom plate 13. After the wedge 23 moves downward, the inclined surface of the wedge 23 contacts the outer wall of the limiting rod 32, and due to the restriction of the limiting rod 32, the clamping top plate 2 is driven to move away from the clamping bottom plate 13, unfolding the clamping bottom plate 13 to facilitate the workers to pick up and put down the frame. At this time, the clamping top plate 2 compresses and stores energy in the return spring 22, and the fixing frame 3 is kept stable on the upper surface of the processing table 1 by the fixing member 31.

[0042] For reciprocating movement, for example, such as Figure 3 As shown, a return spring 22 is provided on one side of the outer wall of the guide rod 21, and the clamping top plate 2 is elastically connected to the outer wall of one side of the guide rod 21 through the return spring 22.

[0043] When in use, when the wedge 23 is released from the limit rod 32, the return spring 22 releases energy and pushes the clamping top plate 2 to move, ensuring the smooth reciprocating movement of the clamping top plate 2.

[0044] When using this utility model, the staff takes the external screws and fixes the L-shaped bracket 12 in the use position through the through holes on both sides of the lower outer wall. The staff places the lower tube of the frame on the upper end of the clamping base plate 13, adjusts the position of the frame to make the weight of both ends of the frame equal, and ensures that the frame is relatively stable on the clamping base plate 13.

[0045] An external hydraulic controller controls the hydraulic cylinder 11 to work. Its push rod moves upward, carrying the clamping base plate 13 and the frame to rise synchronously. The wedge block 23 moves upward as well. When the wedge block 23 is removed from the blocking restriction of the limit rod 32, the clamping top plate 2 moves horizontally outside the guide rod 21 under the elastic force of the return spring 22 until it covers the upper end of the clamping base plate 13. At this time, the lower tube of the frame is firmly clamped between the clamping base plate 13 and the clamping top plate 2, completing the automatic fixation of the frame.

[0046] Based on the processing requirements of different bicycle parts, the height and position of the frame are continuously adjusted by hydraulic cylinder 11 to adapt to different processing scenarios;

[0047] After processing, the hydraulic cylinder 11 is activated to move the push rod downwards, causing the wedge block 23 to descend accordingly. During the descent of the wedge block 23, its inclined surface contacts the outer wall of the limiting rod 32. Under the restriction of the limiting rod 32, the clamping top plate 2 is driven to move away from the clamping bottom plate 13. The clamping top plate 2 compresses and stores energy in the return spring 22, thereby unfolding the clamping bottom plate 13. At this time, the operator can easily remove the frame from the clamping bottom plate 13.

[0048] It should be noted that this utility model is a lifting and processing device for bicycle production.
