Description

Technical Field

[0001] The utility model relates to the field of universal rotary tables, and more specifically to a universal rotary table clamp device. Background Art

[0002] When machining or repairing mechanical parts, the parts need to be clamped on a work bench vise. There are many inventions on the market for clamping parts, such as:

[0003] The patent document with technical disclosure number CN213561205U provides a mechanical processing equipment, which controls the lifting and lowering of the hexagonal rotating sleeve through the threaded connection between the first threaded rod and the hexagonal rotating sleeve. The two ends of the connecting rod are respectively hinged with the hexagonal rotating sleeve and the sliding block, and the sliding connection between the sliding sleeve and the support table can effectively control the simultaneous movement of six blocking plates, thereby fixing the workpiece on all sides.

[0004] The patent document with technical disclosure number CN213647254U provides a mechanical processing device that is easy to fix. The device absorbs external lubricating oil through a pressing ball, squeezes the pressing ball to inject lubricating oil into the main channel through a sealing gasket, and the lubricating oil flows into the inner surface of the thread groove through an auxiliary channel. The threaded rod is rotated by hand with a hand wheel to smoothly lubricate the inside of the threaded groove, thereby avoiding damage to the threaded rod due to large friction.

[0005] At present, the clamps used to clamp parts are mainly divided into two types: multi-jaw linkage and multi-jaw single-action. Multi-jaw linkage is suitable for regular parts such as round parts, while multi-jaw single-action is suitable for irregular parts. There is a lack of devices that can quickly clamp both regular and irregular parts. Therefore, we propose a universal rotary bench clamp device. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a universal rotary bench clamp device.

[0007] To achieve the above-mentioned purpose, the utility model provides a universal rotary bench vise device, which adopts the following technical scheme: a universal rotary bench vise device, comprising a placing table;

[0008] A plurality of screw rods are provided, the screw rods are rotatably arranged in a cross shape in the placement table, and clamping claws for clamping parts are connected to the screw rods;

[0009] A gear ring is rotatably disposed in the placement table and is meshedly connected with a driving gear;

[0010] A sleeve rod, which is arranged corresponding to the screw rod and connected to the screw rod, and on which a driven gear meshing with the gear ring is rotatably connected;

[0011] A transmission rod is slidably connected in the sleeve rod, and the transmission rod and the driven gear are both fixedly connected with face gears, and the two face gears are snap-fitted;

[0012] The base is used to provide steering and support operations for the placement table.

[0013] By adopting the above technical solution, when the two face gears are engaged, the driving gear drives the gear ring to rotate, and the gear ring engages with the driven gear to drive the two engaged face gears to rotate, and the transmission rod and the sleeve rod cooperate to drive the lead screw to rotate, so that the lead screw drives the clamping claws to move, and multiple clamping claws shrink or expand synchronously. When the two face gears are not engaged, the lead screw can be rotated alone to drive the clamping claws connected to it to move.

[0014] Optionally, a slide is fixedly connected to the clamping claw, and the slide is slidably connected to the placement table. A driving groove adapted to the screw rod is opened on the slide, and the screw rod is arranged in the driving groove and threadedly connected to the driving groove.

[0015] By adopting the above technical solution, when the screw rod rotates, it cooperates with the driving groove to drive the slide to translate on the placement table, and the clamping claw moves synchronously with the slide, and multiple clamping claws cooperate to clamp the parts.

[0016] Optionally, a screw is threadedly connected to the transmission rod, one end of the screw is rotatably connected to a slider, the slider is slidably connected to the transmission rod, both sides of the slider are in sliding contact with blocks, and the blocks are snap-fitted with slots provided on the sleeve rod.

[0017] By adopting the above technical solution, the bolt is rotated to drive the slider to move, and the inclined surfaces arranged on both sides of the slider drive the clamping block to slide to the outside of the transmission rod and engage with the clamping groove in the sleeve rod. At this time, the transmission rod is connected and fixed with the sleeve rod, and the transmission rod cannot slide.

[0018] Optionally, a steering ball is fixedly connected to the bottom surface of the placement table, and the steering ball is rotatably matched with the base.

[0019] By adopting the above technical solution, the cooperation between the steering ball and the base can not only rotate the placement table, but also adjust the inclination of the placement table, thereby improving the convenience when processing and repairing parts.

[0020] Optionally, a worm and a worm wheel that mesh with each other are rotatably connected in the base, a stud is fixedly connected to the worm wheel, a brake plate is threadedly connected to the stud, and the brake plate is in abutment with the steering ball.

[0021] By adopting the above technical solution, the worm is rotated to drive the worm wheel and the stud to rotate. When the stud drives the brake plate to rise, the brake plate abuts against the steering ball, and the steering ball cannot rotate in the base, so that the state of the placement table is limited at this time.

[0022] In summary, the utility model includes at least one of the following beneficial technical effects:

[0023] 1. The utility model can adjust the distance between the two face gears when the transmission rod slides in the sleeve rod. When the two face gears are engaged, the gear ring drives the driven gear to rotate, and the two face gears cooperate to drive the lead screw to rotate, so that multiple clamping claws move synchronously. When the two face gears are not engaged, the lead screw can be driven to rotate alone, so that the clamping claws connected thereto move, thereby realizing rapid adjustment according to the shape of the clamped parts and realizing rapid clamping and positioning of different parts;

[0024] 2. The utility model can drive the slider to move by rotating the screw rod, and the slider abuts against the block to move, so that the block is engaged with the sleeve rod, which can prevent the transmission rod from sliding in the sleeve rod, thereby stably limiting the distance between the two face gears.

When the two face gears 10 are engaged, the gear ring 5 drives the driven gear 8 to rotate, the driven gear 8 drives the transmission rod 9 to rotate, and the transmission rod 9 cooperates with the sleeve rod 7 to drive the screw rod 2 to rotate, so that the screw rod 2 drives the clamping claw 4 to move to clamp the parts.

[0032] In the above structure, refer to Figure 2 A handle is eccentrically connected to the outer face gear 10. When the two face gears 10 are not engaged, rotating the handle can drive the face gear 10 to rotate, so that the transmission rod 9 connected thereto drives the sleeve rod 7 to rotate, and the sleeve rod 7 drives the screw rod 2 to rotate.

[0033] In the above structure, refer to Figure 2 The clamping claw 4 is fixedly connected with a slide 3, and the slide 3 is slidably connected to the placement table 1. A driving groove adapted to the screw rod 2 is opened on the slide 3. The screw rod 2 is arranged in the driving groove and is threadedly connected with the driving groove. When the screw rod 2 rotates, it cooperates with the driving groove to drive the slide 3 to translate on the placement table 1, and the clamping claw 4 moves synchronously with the slide 3. Multiple clamping claws 4 cooperate to clamp the parts.

[0034] In the above structure, refer to Figure 3 A screw rod 11 is threadedly connected to the transmission rod 9, and a slider 12 is rotatably connected to one end of the screw rod 11. The slider 12 is slidably connected to the transmission rod 9. Blocks 13 are in sliding contact on both sides of the slider 12. The block 13 is engaged with the slot provided on the sleeve rod 7. The slider 12 is driven to move by rotating the bolt. The inclined surfaces provided on both sides of the slider 12 drive the block 13 to slide toward the outside of the transmission rod 9 and engage with the slot in the sleeve rod 7. At this time, the transmission rod 9 is connected and fixed to the sleeve rod 7, and the transmission rod 7 cannot slide; a knob is fixedly connected to one end of the screw rod 11, and rotating the knob can drive the screw 11 to rotate.

When the worm 16 is rotated to drive the worm wheel 17 and the stud 18 to rotate, and the stud 18 drives the brake plate 19 to rise, the brake plate 19 is in abutment with the steering ball 15, and the steering ball 15 cannot rotate in the base 14, so that the state of the placement table 1 is limited at this time.

[0037] The implementation principle of a universal rotary bench vise device in an embodiment of the utility model is as follows: a part is placed on a placement table 1. If the part is of a regular shape, a transmission rod 9 is slid into a sleeve rod 7 to engage two face gears 10. The rotating bolt drives the slider 12 to move. The slider 12 drives the clamping block 13 to engage the sleeve rod 7. At this time, the transmission rod 7 cannot slide. The crank is turned to drive the driving gear 6 to drive the gear ring 5 to rotate. The gear ring 5 drives the driven gear 8 to rotate. The driven gear 8 cooperates with the two engaged face gears 10 to drive the transmission rod 9 to rotate. The transmission rod 9 cooperates with the sleeve rod 7 to drive the screw rod 2 to rotate. The screw rod 2 drives the clamping claw 4 to move. Multiple clamping claws 4 move synchronously to quickly position and clamp regular parts.

[0038] If the part is irregular in shape, pull the transmission rod 9 toward the outside of the sleeve rod 7 to cancel the engagement of the two face gears 10. At this time, the handle can be turned to drive the outer face gear 10 to rotate. The face gear 10 cooperates with the transmission rod 9 to drive the sleeve rod 7 to rotate. The sleeve rod 7 cooperates with the screw rod 2 to drive the clamping claw 4 to move. Multiple clamping claws 4 move individually to clamp the irregular shaped parts.
