Technical Field

[0001] The utility model relates to a clamp used for machining, in particular to a moment-controllable vise clamp. Background Art

[0002] As we all know, in the field of machining, the use of fixtures is indispensable. The workpiece to be processed is clamped by the fixture to meet the needs of turning, milling, drilling, etc. of the clamped workpiece.

[0003] At present, in the existing CNC processing, some products need to be clamped with a vise to prevent them from vibrating or falling during the processing; however, the processed products have different shapes. For example, if the middle is hollow or the structural strength is not very good, the force used by the personnel to operate the vise is different during clamping, which will cause the vise to press the product to different degrees, such as being too tight or not tight enough, which will cause the product to be crushed, deformed or not pressed tightly enough.

[0004] Therefore, there is an urgent need for a torque controllable vise clamp to overcome one or more of the above-mentioned defects. Utility Model Content

[0022] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the embodiments and the accompanying drawings.

[0023] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 The torque controllable vise clamp 100 of the utility model comprises a clamp seat 10, a screw rod 20, a nut 30, a first clamping block 40, a second clamping block 50, a torque wrench 60 and an intermediate set 70. The screw rod 20 is rotatably mounted on the clamp seat 10 to meet the need of the screw rod 20 rotating relative to the clamp seat 10. The nut 30 is slidably sleeved on the screw rod 20 to meet the need of the nut 30 being driven by the screw rod 20 and sliding on the screw rod 20 during the rotation of the screw rod 20. The first clamping block 40 and the second clamping block 50 are clamped on the clamp seat 10, and the second clamping block 50 is also fixedly connected to the nut 30 to meet the need of the second clamping block 50 sliding on the screw rod 20 together with the nut 30, thereby achieving the purpose of the second clamping block 50 sliding relative to the first clamping block 40. The first end of the screw rod 20 passes through the side of the clamp seat 10 to form a passing end 21. The first end 71 of the intermediate set piece 70 is used to be set and connected with the torque wrench 60, and the second end 72 of the intermediate set piece 70 is used to be set and connected with the through-end 21, so that the torque wrench 60 is assembled and connected with the screw rod 20 by means of the intermediate set piece 70, so that the operator can operate the torque wrench 60 to finally achieve the purpose of opening and closing the second clamping block 50 relative to the first clamping block 40. It should be noted that although Figures 3 to 5 The second clamping block 50 is shown to be fixedly connected to the nut 30. Obviously, according to actual needs, the first clamping block 40 can also be fixedly connected to the nut 30. Figures 3 to 5 More specifically, as follows:

[0024] Combination Figures 3 to 5As an example, the first clamp block 40 and the second clamp block 50 are both located directly above the screw rod 20, and the nut 30 is located directly below the second clamp block 50; this design avoids the screw rod 20 and the nut 30 from affecting the product 200 clamped by the first clamp block 40 and the second clamp block 50 due to their arrangement above the second clamp block 40. At the same time, the torque wrench 60 is provided with a fitting hole 61 with a polygonal cross-sectional profile, the cross-sectional profile of the through-end 21 is a polygon, and the first end 71 of the intermediate fitting 70 is fitted into the fitting hole 61 in a matching manner; the second end 72 of the intermediate fitting 70 is provided with a matching hole 721 matching the through-end 21, and the through-end 21 is fitted into the matching hole 721; this design makes the fitting connection between the intermediate fitting 70 and the through-end 21 a detachable fitting connection, thereby facilitating the operator to assemble and disassemble the intermediate fitting 70 from the through-end 21; similarly, the fitting connection between the intermediate fitting 70 and the torque wrench 60 is also a detachable fitting connection. Specifically, in combination with Figures 3 to 5 As an example, the set hole 61 and the matching hole 721 are both hexagonal holes 21, and the through-end 21 and the first end 71 of the intermediate set piece 70 are both hexagonal shaft structures; so as to simplify the set connection between the intermediate set piece 70 and the through-end 21, and the set connection between the intermediate set piece 70 and the torque wrench 60. In addition, the torque wrench 60 is a manual torque wrench.

[0025] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, as an example, the clamp seat 10 is provided with a through passage 11 that passes through from top to bottom and a slide groove 13 that passes through two first side walls 12 opposite to the clamp seat 10 along the axial direction of the screw rod 20, and the slide groove 13 is connected to the through passage 11. The first clamp block 40 crosses the slide groove 13 from above, and the first clamp block 40 is also assembled on two second side walls 14 opposite to the clamp seat 10, and the two second side walls 14 are separated in the cross direction of the first clamp block 40 (see arrow C). The first end 21 of the screw rod 20 passes through one of the two first side walls 12, and the second end 22 of the screw rod 20 is rotatably assembled on the other of the two first side walls 12; such a design allows both ends of the screw rod 20 to be supported, thereby making the rotation of the screw rod 20 more reliable. The second clamping block 50 is slidably arranged in the sliding groove 13 to improve the smoothness and reliability of the sliding of the second clamping block 50 on the clamping seat 10; in addition, with the help of the sliding groove 13 penetrating the two opposite first side walls 12 of the clamping seat 10, the disassembly and assembly operation of the second clamping block 50 on the clamping seat 10 is facilitated; with the help of the through channel 11, the assembly and disassembly operation between the nut 30 and the second clamping block 50 is facilitated. This is because the nut 30 is located directly below the second clamping block 50, and the nut 30 and the second clamping block 50 can only be assembled and disassembled from the bottom.

[0026] like Figure 2 and Figure 3 As shown, as an example, the clamp seat 10 is also provided with an embedding groove 15 that penetrates the two second side walls 14 along the horizontal direction of the first clamp block 40, and the embedding groove 15 also penetrates the two second side walls 14 upward, and the first clamp block 40 is provided with an embedding convex strip 41, which is embedded in the embedding groove 15 in a matching manner; such a design facilitates the assembly and disassembly operation between the first clamp block 40 and the clamp seat 10. Specifically, Figure 2 As an example, the projections of both the embedding groove 15 and the embedding ridge 41 in the transverse direction of the first clamping block 40 are inverted trapezoids, such as but not limited to isosceles trapezoids, so it is easy to manufacture and process, and the first clamping block 40 can be reliably assembled on the clamping seat 10.

[0027] like Figure 3 As shown, as an example, an arc-shaped arched structure 16 protruding from the slide groove 13 is provided on either of the two first side walls 12. Optionally, as an example, the arched structure 16 is a semicircular ring for easy manufacturing and processing; in addition, the arched structure 16 surrounds the screw rod 20 from above, on the one hand, it provides support for the screw rod 20, and on the other hand, it does not cause an obstacle to the sliding of the second clamping block 50 slidably arranged on the slide groove 13.

[0028] Compared with the prior art, since the torque-controllable vise clamp 100 of the utility model also includes a torque wrench 60 and an intermediate set component 70, the first end 71 of the intermediate set component 70 is used to be set and connected with the torque wrench 60, and the second end 72 of the intermediate set component 70 is used to be set and connected with the outlet end 21, the operator can control the consistency of the locking force of the first clamping block 40 and the second clamping block 50 on the product 200 through the torque wrench 60, thereby overcoming the traditional problem that the product is deformed or not pressed tightly due to the different locking forces of the operator, thereby improving the clamping efficiency and saving costs.

[0029] It is worth noting that the direction indicated by the double arrow A in the figure is the axial direction of the screw rod 20, the direction indicated by the arrow C is the cross direction of the first clamping block 40, and the direction indicated by the arrow B is the direction from bottom to top of the clamping seat 10. In addition, since the specific structure of the torque wrench 60 and the principle of controlling the torque are well known in the art, they will not be described here.

[0030] The above disclosure is only a preferred example of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
