Description

Technical Field

[0001] This utility model relates to the field of machining, and more particularly to a fixing clamp and bench vise device. Background Technology

[0002] A bench vise is an essential tool in a fitter's workshop, usually mounted on a workbench, and is mainly used to clamp and secure workpieces. Its working principle is that the rotation of a screw rod (lead screw) moves the movable jaws towards the fixed jaws, thereby clamping and releasing the workpiece, allowing cutting, grinding, or engraving operations to proceed smoothly.

[0003] Long-term use has proven that although bench vises have comprehensive advantages such as simple operation, good tightening, stable clamping, and flexible repositioning, their shortcomings include slow forward and backward movement of the movable jaw due to the clumsy movement of the insert pins. In fact, there is a rigid contact between the square insert pins on the lower part of one side of the movable jaw and the insert cavity on the lower part of one side of the fixed jaw, and this rigid contact inevitably generates a certain amount of resistance due to friction.

[0004] Therefore, there is a need to provide a bench vise device that can facilitate rapid movement of the movable jaw. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a fixed clamp and bench vise device. The device makes the insertion and removal of the insert plate flexible and quick by sliding the pulley and the slide groove, which solves the practical problem of slow forward and backward movement of the movable clamp body, saves time and improves work efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: it includes a chassis, a fixed clamp body and a movable clamp body, wherein the chassis, the fixed clamp body and the movable clamp body are all made of stainless steel.

[0007] The upper side of the chassis has a centrally located opening for the connecting part to pass through. The lower outer edge of the chassis has a fixed edge with screw holes. A bearing is located on the lower side inside the chassis. A right clamping block is located on the upper part of one side of the fixed clamp body. A right threaded sleeve is located at the center of the lower part of one side of the fixed clamp body. A right threaded cavity is laterally located inside the central section of the lower part of the fixed clamp body. A support plate is located on the lower side of the fixed clamp body. An inlet / outlet for the insertion plate is located on the outer side of one end of the support plate. Sliding grooves are located on the lower sides of both sides of the support plate. A connecting part is located on the lower side of the support plate, and the connecting part is fixedly connected to the chassis. The movable clamp body... A left clamping block is provided on the upper side. A left threaded sleeve is provided in the center of the lower part of the movable clamp body. A left screw cavity is provided laterally inside the center section of the lower part of the movable clamp body. An insert plate is provided on the lower side of the movable clamp body. Four pulleys are evenly provided on one end of each side of the insert plate. One end of the insert plate is embedded in the inner cavity of one end of the support plate. Each pulley is embedded in a corresponding groove. The screw cavity is equipped with a matching screw rod. A crank is movably provided at one end of the screw rod. The other end of the screw rod is screwed through the inner cavities of the left and right threaded sleeves. A limiting plate is provided at the end of one end of the screw rod located in the right screw cavity.

[0008] The beneficial technical effects of this utility model are: the sliding connection between the pulley and the slide groove makes the insertion plate move in and out flexibly and quickly, solving the practical problem of slow forward and backward movement of the movable clamp body, saving time and improving work efficiency; by increasing the length and width of the insertion plate and the insertion cavity, the connection surface between the two can be effectively expanded, improving the stability of the movable clamp body during operation and solving the problem of slight shaking caused by the connection surface being too small.

[0014] The present invention will now be further described with reference to the accompanying drawings.

[0015] It should be noted that the terms "upper side", "lower side", "one side", "one end", "left / right", "center", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] It should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "set up / have," "connected," and "fixed," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms based on the specific circumstances.

[0017] Please refer to Figure 1 The chassis 1 is a circular structure, the fixed clamp body 2 is a rectangular solid structure, and the movable clamp body 6 is a 7-shaped solid structure.

[0018] Chassis 1: The upper center of the chassis 1 is provided with a circular opening that can only accommodate the connecting part 12. The lower outer edge of the chassis 1 is provided with a fixed edge, and four fixing screw holes are evenly provided on the fixed edge. Each of the four fixing screw holes is equipped with a matching fixing screw. The interior of the chassis 1 is a cavity structure.

[0019] A bearing 13 is horizontally arranged in the lower center of the chassis 1, and the inner cavity of the bearing 13 is aligned with the opening. During operation, the bearing 13 can reduce the coefficient of friction by rotating with precision, so that the connecting part 12 can achieve the purpose of separate precision rotation.

[0020] The fact is that the flexible rotation of the bench vise is beneficial for grinding, polishing or engraving all sides of the workpiece 17.

[0021] Fixed clamp body 2: A rectangular carbon steel right clamping block 3 is provided on the upper part of one side of the fixed clamp body 2, and linear anti-slip teeth are evenly provided on one side of the right clamping block 3; during operation, the two clamping blocks on the left and right tightly clamp and stabilize the workpiece 17.

[0022] A hexagonal right-hand threaded sleeve 5 is provided at the lower center of one side of the fixed clamp body 2. The right-hand threaded sleeve 5 supports the spiral rod 15 and can also form a threaded screw-in connection.

[0023] A cylindrical right screw cavity 4, which can comfortably accommodate the screw rod 15, is laterally arranged inside the middle section of the lower part of the fixing clamp body 2, facing the inner cavity of the right screw sleeve 5. One end of the right screw cavity 4 is connected to the inner cavity of the right screw sleeve 5, and the other end does not penetrate the outer side of the fixing clamp body 2 at the corresponding location.

[0024] As shown in the figure, a rectangular hollow support plate is provided on the lower side of the fixed clamp body 2. The outer side of one end of the support plate is provided with the inlet and outlet of the insertion plate 10. The two lower sides of the support plate are provided with longitudinal sliding grooves 11. The sliding grooves 11 can not only limit the position of the pulley 14 at the bottom of the insertion plate 10, but also effectively support and guide the movement of the pulley 14.

[0025] A cylindrical stainless steel connecting part 12 is vertically arranged at the center of the lower side of the tray. The connecting part 12 passes through the opening on the upper side of the chassis 1 and is then firmly fixed in the bearing 13.

[0026] Movable clamp body 6: A rectangular carbon steel left clamping block 7 is provided on the upper part of one side of the movable clamp body 6, and linear anti-slip teeth are evenly provided on one side of the left clamping block 7; during operation, the two clamping blocks tightly clamp and stabilize the workpiece 17.

[0027] The two clamping blocks on the left and right are not only at the same height, but also have the same specifications.

[0028] A hexagonal left threaded sleeve 9 is provided at the lower center of one side of the movable clamp body 6. The left threaded sleeve 9 supports the spiral rod 15 and can also form a threaded screw-in connection.

[0029] A cylindrical left screw cavity 8 is provided horizontally inside the lower central section of the movable clamp body 6, which can comfortably accommodate the screw rod 15. One end of the left screw cavity 8 is connected to the inner cavity of the left screw sleeve 9, and the other end is connected to the outer side of the movable clamp body 6 at the corresponding location.

[0030] The lower side of the movable clamp body 6 is provided with a rectangular insert plate 10 that matches the inner cavity of the tray.

[0031] In reality, when the upper sides of the two clamps are on the same horizontal line, the two screw sleeves are aligned.

[0032] In reality, when the upper sides of the two clamps are on the same horizontal line, the insert plate 10 is aligned with the inner cavity of the tray.

[0033] Please refer to Figure 2 The insert plate 10 has four pulleys 14 on one end of its lower side. After the pulleys 14 are movably connected with the slide groove 11, a sliding effect can be produced, making the movable clamp body 6 move flexibly and quickly.

[0034] One end of the insert plate 10 is horizontally embedded in the inner cavity of the other end of the support plate. The pulleys 14 on the lower sides of the insert plate 10 are respectively embedded in the inner cavities of the corresponding sliding grooves 11, and then a sliding connection mode is formed.

[0035] The screw cavity is equipped with a matching helical rod 15. The screw on the outer circle of the helical rod 15 matches the threads on the inner walls of the two screw sleeves. The main function of the helical rod 15 is to movably connect the two clamp bodies.

[0036] One end of the spiral rod 15 is provided with a crank sleeve, and the crank sleeve has a longitudinal cavity that can only accommodate one end of the crank 16. The other end of the spiral rod 15 is screwed through the inner cavity of the left threaded sleeve 9 and the right threaded sleeve 5 and extends further inward. The other end of the spiral rod 15 is provided with a circular limiting plate. The limiting plate can play a regular limiting role on the other end of the spiral rod 15, so that it will not come out of the right threaded sleeve 5 when moving in the opposite direction.

[0037] Please refer to Figure 3 The crank sleeve at one end of the spiral rod 15 is equipped with a matching cylindrical crank handle 16. One end of the crank handle 16 is movably disposed inside the crank sleeve, and the other end of the crank handle 16 is provided with a ball head for easy gripping.

[0038] The length of the crank handle 16 is greater than the height of the fixed clamp body 2 or the movable clamp body 6. The crank handle 16 can easily and quickly crank the screw rod 15 in accordance with Archimedes' lever principle.

[0039] Working principle of pulley 14: When the operator turns the screw rod 15 inward or outward, the left screw sleeve 9 will cause the insert plate 10 at the lower part of the movable clamp body 6 to move. At the same time as the insert plate 10 moves, the pulleys 14 on both sides of its lower part will slide flexibly in the corresponding grooves 11 (see...). Figure 3 ).

[0040] The principle of movable clamp body 6: The rotation of the screw rod 15 (lead screw) drives the movable clamp body 6 to move horizontally closer to or open to the fixed clamp body 2, thereby achieving the purpose of clamping and releasing the workpiece 17, so that cutting, grinding or engraving operations can be carried out smoothly.

[0041] In reality, turning the screw rod 15 in the forward direction will cause the insert plate 10 to be inserted inward and push the movable clamp 6 and the fixed clamp 2 closer together; turning the screw rod 15 in the reverse direction will cause the insert plate 10 to be withdrawn outward and cause the movable clamp 6 and the fixed clamp 2 to be separated.

[0042] Please refer to Figure 4 The bench vise, also known as a bench vise or workpiece vise, is mainly used to clamp and stabilize workpieces. It is usually made up of a certain number of fixing screws installed on the upper side of the worktable 18.

[0043] The working process of this vise is as follows: 1. The operator cranks the handle 16 with one hand while holding the workpiece 17 horizontally with the other hand; 2. As the screw rod 15 is continuously screwed in, the insert plate 10 is slowly inserted into the inner cavity of one end of the support plate; 3. The workpiece 17 is suspended in the clamping jaws between the left and right clamping blocks; 4. The screw rod 15 is tightened again, and the left and right clamping blocks tightly clamp the workpiece 17; 5. The operator performs grinding operations on the workpiece 17.

[0044] This utility model provides a fixed clamp and bench vise device, which: firstly, solves the practical problem of slow forward and backward movement of the movable clamp body, thus improving work efficiency; and secondly, solves the practical problem of slight shaking caused by the small connection surface between the insert plate and the insert cavity, thus improving the stability of the movable clamp body during operation.
