Description

Technical Field

[0001] This utility model relates to the field of gear technology, and in particular to a quick positioning fixture for gear sets. Background Technology

[0002] In the machinery manufacturing industry, gear sets are important transmission components, and their machining accuracy and production efficiency directly affect the overall performance of mechanical equipment.

[0003] Most traditional gear fixtures use bolt fastening and pin positioning structures. After the gear is processed, operators need to use special tools to loosen the bolts and pull out the pins one by one. The operation is cumbersome and time-consuming. In addition, some fixture designs do not fully consider the ease of disassembly. During disassembly, parts are prone to jamming and interference, which not only increases the difficulty of disassembly but may also damage the fixture and gear workpiece, leading to increased equipment maintenance costs and reduced production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology of traditional gear clamps usually requires bolts and pins for fastening and positioning, and special tools are needed to loosen and pull them out after processing, which is complicated and time-consuming. To this end, we propose a quick positioning clamp for gear sets.

[0005] To achieve the above objectives, this application adopts the following technical solution: a quick positioning fixture for a gear set, comprising an operating table, two drive cylinders mounted on the top of the operating table, a U-shaped block mounted on one side of each drive cylinder, a gear clamp slidably connected inside the U-shaped block, insertion slots at both ends of the gear clamp, two openings at the top of the U-shaped block, a baffle fixedly connected inside the openings, an adjusting rod slidably connected inside the baffles, an arc-shaped pushing block fixedly connected to the bottom of the adjusting rod, an arc-shaped force-bearing block abutting one side of the arc-shaped pushing block, an insertion rod fixedly connected to one side of the arc-shaped force-bearing block, and a through slot on one side of the inner cavity of the openings.

[0006] Preferably, the surface of the plug rod is slidably connected to the inside of the plug groove, and the outer diameter of the plug rod is adapted to the inner diameter of the plug groove.

[0007] Preferably, both ends of the groove inner cavity are provided with sliding grooves, and both ends of the arc-shaped force-bearing block are fixedly connected with sliders.

[0008] Preferably, a return spring is fixedly connected to one side of the arc-shaped force-bearing block, and one side of the return spring is fixedly connected to the inside of the slot.

[0009] Preferably, a plurality of positioning rods are fixedly connected to one side of the U-shaped block, and a plurality of positioning holes are provided on one side of the gear clamp.

[0010] Preferably, two square grooves are formed on one side of the U-shaped block, and a storage spring is fixedly connected inside the square groove. A storage block is fixedly connected to one side of the storage spring.

[0011] Preferably, both ends of the inner cavity of the square groove are provided with limiting grooves, and both ends of the energy storage block are fixedly connected with limiting blocks.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operator pulls the adjusting rod upward, causing the adjusting rod to drive the arc-shaped pushing block to move upward, so that one side of the arc-shaped pushing block leaves the contact surface of the arc-shaped force block. At this time, the reset spring pushes the arc-shaped force block back by its own elasticity, and the arc-shaped force block then drives the insertion rod to be pulled out of the insertion slot, realizing the rapid disassembly of the gear clamp, thus facilitating the operator to replace or maintain the gear clamp.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-4As shown, this utility model provides a technical solution: a quick positioning fixture for a gear set, including an operating table 1. Two drive cylinders 2 are mounted on the top of the operating table 1. A U-shaped block 3 is mounted on one side of each drive cylinder 2. A gear clamp 4 is slidably connected inside the U-shaped block 3. Both ends of the gear clamp 4 are provided with insertion slots 5. Two slots 6 are provided on the top of the U-shaped block 3. A baffle 7 is fixedly connected inside the slots 6. An adjusting rod 8 is slidably connected inside the baffle 7. An arc-shaped pushing block 9 is fixedly connected to the bottom of the adjusting rod 8. An arc-shaped force-bearing block 10 abuts against one side of the arc-shaped pushing block 9. An insertion block 10 is fixedly connected to one side of the arc-shaped force-bearing block 10. The connecting rod 11 has a through slot 12 on one side of the inner cavity of the slot 6. A return spring 15 is fixedly connected to one side of the arc-shaped force block 10. One side of the return spring 15 is fixedly connected to the inside of the slot 6. When the operator pulls the adjusting rod 8 upward, the adjusting rod 8 drives the arc-shaped pushing block 9 to move upward, so that one side of the arc-shaped pushing block 9 leaves the contact surface of the arc-shaped force block 10. At this time, the return spring 15 pushes the arc-shaped force block 10 back by its own elasticity. The arc-shaped force block 10 then drives the connecting rod 11 to be pulled out from the connecting slot 5, realizing the rapid disassembly of the gear clamp 4, which makes it convenient for the operator to replace or maintain the gear clamp 4.

[0022] Reference Figure 3 and Figure 4 As shown in this embodiment: the surface of the plug rod 11 is slidably connected to the inside of the plug groove 5, and the outer diameter of the plug rod 11 is adapted to the inner diameter of the plug groove 5. Through the sliding connection design between the plug rod 11 and the plug groove 5, not only is the stable installation of the gear clamp 4 in the U-shaped block 3 achieved, but the smoothness of the disassembly process is also ensured. The precise adaptation between the outer diameter of the plug rod 11 and the inner diameter of the plug groove 5 effectively prevents the gear clamp 4 from shaking or falling off during use, ensuring the stability and reliability of the clamp.

[0023] Reference Figure 4 As shown in this embodiment: both ends of the inner cavity of the slot 6 are provided with sliding grooves 13, and both ends of the arc-shaped force block 10 are fixedly connected with sliders 14. Through the sliding connection design between the sliders 14 and the sliding grooves 13, the movement of the arc-shaped force block 10 in the inner cavity of the slot 6 is more stable, effectively avoiding jamming or displacement of the arc-shaped force block 10 during movement, and further ensuring the accuracy and efficiency of disassembly and installation of the gear clamp 4.

[0024] Reference Figure 2 and Figure 3As shown in this embodiment: multiple positioning rods 17 are fixedly connected to one side of the U-shaped block 3, and multiple positioning holes 18 are opened on one side of the gear clamp 4. Through the precise cooperation between the positioning rods 17 and the positioning holes 18, the gear clamp 4 is firmly positioned on the U-shaped block 3, which effectively improves the stability and accuracy of the gear clamp 4 installation. In actual operation, the operator only needs to slide the gear clamp 4 to the insertion groove 5 through the insertion rod 11, and then connect the positioning rods 17 to the positioning holes 18 to further ensure the stability and ease of operation of the clamp.

[0025] Reference Figure 5 As shown in this embodiment: two square grooves 19 are opened on one side of the U-shaped block 3. A storage spring 20 is fixedly connected inside the square groove 19. A storage block 21 is fixedly connected to one side of the storage spring 20. When the gear clamp 4 is released from the U-shaped block 3, the storage spring 20 will release the stored energy and push the storage block 21 to pop out quickly, so that the gear clamp 4 can be quickly separated from the U-shaped block 3.

[0026] Reference Figure 5 As shown in this embodiment: both ends of the inner cavity of the square groove 19 are provided with limiting grooves 22, and both ends of the energy storage block 21 are fixedly connected with limiting blocks 23. Through the cooperation of the limiting grooves 22 and the limiting blocks 23, the movement trajectory of the energy storage block 21 is limited and guided, ensuring that the energy storage block 21 can be smoothly ejected under the push of the energy storage spring 20, and avoiding the energy storage block 21 from deviating or getting stuck during the movement.

[0027] Working principle: By pulling the adjusting rod 8 upwards, the operator drives the arc-shaped pushing block 9 upwards, causing one side of the arc-shaped pushing block 9 to leave the contact surface of the arc-shaped force block 10. At this time, the return spring 15 pushes the arc-shaped force block 10 back using its own elasticity. The arc-shaped force block 10 then drives the insertion rod 11 to be pulled out of the insertion slot 5, realizing the rapid disassembly of the gear clamp 4. This facilitates the replacement or maintenance of the gear clamp 4 by the operator. The sliding connection design between the insertion rod 11 and the insertion slot 5 not only ensures the stable installation of the gear clamp 4 in the U-shaped block 3, but also ensures the smoothness of the disassembly process. The outer diameter of the insertion rod 11 is precisely matched with the inner diameter of the insertion slot 5, effectively preventing the gear clamp 4 from shaking or falling off during use, ensuring the stability and reliability of the clamp. The sliding connection design between the slider 14 and the slide groove 13 makes the movement of the arc-shaped force block 10 in the inner cavity of the slot 6 more stable, effectively avoiding the arc-shaped force block 10 moving too far. During the process, if there is any jamming or deviation, the accuracy and efficiency of disassembly and installation of the gear clamp 4 are further ensured. The precise cooperation between the positioning rod 17 and the positioning hole 18 ensures that the gear clamp 4 is firmly positioned on the U-shaped block 3, effectively improving the stability and accuracy of the gear clamp 4 installation. In actual operation, the operator only needs to slide the gear clamp 4 through the insertion rod 11 and the insertion slot 5, and then connect the positioning rod 17 and the positioning hole 18 to further ensure the stability and ease of operation of the clamp. When the gear clamp 4 is released from the U-shaped block 3, the energy storage spring 20 will release the stored energy and push the energy storage block 21 to pop out quickly, so that the gear clamp 4 can be quickly separated from the U-shaped block 3. Through the cooperation of the limiting groove 22 and the limiting block 23, the movement trajectory of the energy storage block 21 is limited and guided, ensuring that the energy storage block 21 can pop out smoothly under the push of the energy storage spring 20, and avoiding the displacement or jamming of the energy storage block 21 during the movement.
