[0001] This utility model relates to the field of bench vise technology, specifically to a bench vise device. Background Technology

[0002] The coal mining industry has a lot of machinery and equipment, and bench vises are used to clamp workpieces during routine maintenance. Therefore, bench vises are an essential tool in fitter's workshops.

[0003] Traditional bench vises have relatively low working efficiency. They use threaded drives, which prevents them from clamping and releasing quickly, resulting in low production efficiency. In addition, traditional bench vises can only be used by hand to tighten the handle when clamping workpieces. If other tools are used to assist in applying force, accidents can easily occur, resulting in insufficient clamping force. Utility Model Content

[0004] The purpose of this invention is to provide a bench vise device to solve the problems mentioned in the background art.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a bench vise device, comprising: a cast iron support body 1, with a fixed clamp 13 welded to the end of the support body 1, the fixed clamp 13 and the support body 1 forming an inverted L-shaped structure; a hydraulic drive unit located on one side of the support body 1, with a connecting rod 7 on one side of the hydraulic drive unit for driving the extension and retraction of the hydraulic drive unit, and a movable clamp 11 fixedly connected to the output end of the hydraulic drive unit; a rotary drive unit located at the end of the support body 1, the rotary drive unit including a drive pressure rod 18 for driving the connecting rod 7, a connecting block 17 rotatably connected to the bottom of the drive pressure rod 18, and a rotating ring 15 rotatably mounted on the end of the support body 1 fixedly connected to the bottom of the connecting block 17 for driving the connecting rod 7 to move at different angles.

[0024] It should be noted that in this utility model, the support body 1 is fixedly installed in a designated position, and the drive pressure rod 18 is rotated around the connecting rod 7 to a suitable angle. By reciprocating up and down at one end of the drive pressure rod 18, since the end of the drive pressure rod 18 is rotatably connected to the connecting block 17, under the action of the lever principle, the T-shaped rod 3 slides in the middle of the drive pressure rod 18. The drive pressure rod 18 drives the connecting rod 7 to reciprocate up and down through the T-shaped rod 3. The connecting rod 7 drives the output end of the jack 6 to rise. The output end of the jack 6 drives the movable chuck 11 to slide along the limiting slide bar 9. The movable chuck 11 moves closer to the position of the fixed chuck 13, thereby clamping the workpiece between the fixed chuck 13 and the movable chuck 11.

[0025] Please see Figure 1 , 2 As shown, the end of the support body 1 is provided with a second fixing slot 4, and a fastening bolt 5 is threadedly connected to the middle of the second fixing slot 4. A first fixing slot 2 is opened on the side of the support body 1 adjacent to the second fixing slot 4.

[0026] It should be noted that when the support body 1 needs to be used vertically, the first fixing slot 2 is clamped onto the edge of the table or the crossbeam, and the bolt is screwed from the bottom of the first fixing slot 2 so that the bolt extends into the first fixing slot 2. In this way, the table or the crossbeam is pressed and fixed by the bolt. When the support body 1 needs to be fixed horizontally, the second fixing slot 4 is clamped into the position to be fixed, and the fastening bolt 5 is rotated so that the inner wall of the second fixing slot 4 at the fixed position fits, thereby fixing the support body 1 in the designated position.

[0027] Please see Figure 1 As shown, the hydraulic drive unit is a jack 6, and the handle of the jack 6 is fixedly connected to the connecting rod 7.

[0028] It should be noted that the bottom of the jack 6 of this utility model is fixed to the bottom of the support body 1 by bolts, and the lifting handle of the jack 6 is connected to the connecting rod 7. By moving up and down through the lifting handle, based on Pascal's law, the pressure is converted into lifting force through the transmission of hydraulic oil.

[0029] Please see Figure 1 , 2 As shown in Figure 3, a support plate 8 is fixedly connected to one side of the support body 1. Two limiting slide rods 9 are fixedly connected between the support plate 8 and the fixed clamp 13. A movable slide sleeve 10 is slidably arranged on the outside of the limiting slide rod 9. The movable slide sleeve 10 is fixedly connected to the movable clamp 11. A spring 12 is sleeved on the outside of the limiting slide rod 9 and between the movable slide sleeve 10 and the fixed clamp 13.

[0030] It should be noted that when the connecting rod 7 drives the movable chuck 11 to rise, the movable chuck 11 slides along the limiting slide bar 9 and compresses the spring 12. Under the action of the two limiting slide bars 9, the stability of the movable chuck 11 in raising and lowering is ensured. After clamping is completed, the exhaust valve on one side of the bottom of the jack 6 is rotated to allow the hydraulic oil in the jack to flow back, thereby eliminating the hydraulic pressure. The spring 12 resets and drives the movable chuck 11 to slide along the limiting slide bar 9. The moving sleeve 10 drives the telescopic end of the jack 6 to reset through the movable chuck 11.

[0031] Please see Figure 1 , 2 As shown in Figures 4 and 5, a limiting cover 16 is slidably connected to the outer side of the rotating ring 15. The limiting cover 16 is fixedly connected to the support body 1. A connecting plate 14 is rotatably connected to the top of the connecting rod 7. T-shaped rods 3 are symmetrically fixedly connected to both sides of the connecting plate 14. Limiting grooves 19 are provided on both sides of the driving pressure rod 18. The T-shaped rods 3 pass through the limiting grooves 19 and are slidably connected to the limiting grooves 19.

[0032] It should be noted that, in this utility model, the rotating ring 15 is limited to the end of the support body 1 by the limiting cover 16, so that the rotating ring 15 rotates around the connecting rod 7, the T-shaped rod 3 slides in the limiting groove 19, and a vertical limiting rod is provided at its end, so that the T-shaped rod 3 slides along the limiting groove 19 without deflection, thereby driving the driving pressure rod 18 to rotate around the connecting rod 7, so that the driving pressure rod 18 can face different positions, and then the driving pressure rod 18 moves up and down around the end of the connecting block 17, thereby driving the jack 6 to rise through the connecting rod 7.
