Description

Technical Field

[0001] The utility model relates to the field of clamps, in particular to a fast clamping fixture for bar-shaped workpieces. Background Art

[0002] Existing bar-shaped workpieces (such as rectangular steel pipes, sheet metal blocks, etc.) need to be clamped and fixed during processing. The existing clamping method generally fixes the bar workpiece through a block matched with an OK clamp. However, the OK clamps of this method are fixed and installed by bolts. Therefore, it is not convenient to adaptively adjust bar workpieces of different lengths and sizes, which greatly reduces the practicality of the clamping tooling. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a fast clamping fixture for bar-shaped workpieces to solve the problems existing in the above-mentioned background technology.

[0004] The utility model provides the following technical solution: a quick clamping tool for bar-shaped workpieces, comprising a base plate, a baffle and an OK clamp, a card slot being provided on the back of the base plate, the baffle being detachably mounted in the card slot, a slide slot being provided at the front end of the base plate, a plurality of sliders being slidably connected to the interior of the slide slot, and the top surface of the slider being flush with the top surface of the base plate, the top surface of each slider being detachably connected to an OK clamp, and the OK clamp being slidably placed on the top surface of the base plate through the slider.

[0005] Furthermore, a limiting groove is provided on the back side of the slide groove, and a protrusion is integrated on the back of the slider. The protrusion is placed in the limiting groove and is slidably connected to the limiting groove.

[0006] Furthermore, a non-slip pad is adhered and connected to the front end of the slider, and the sum of the width of the non-slip pad and the slider is smaller than the width of the slide groove.

[0007] Furthermore, the slot and the top surface of the baffle are each provided with a plurality of holes corresponding to each other.

[0008] Furthermore, the anti-slip pad is made of rubber material.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The utility model installs the OK clamp on the slider, and slides the slider into the slide groove opened in the bottom plate, so that the OK clamp can be moved to any position on the top surface of the bottom plate, which can be used for bar-shaped workpieces of different sizes, greatly improving the practicability of the clamping tooling. At the same time, the clamping end of the OK clamp contacts and abuts the workpiece, and the abutting force gives the OK clamp a force to move backward, forcing the OK clamp to move backward, so that the OK clamp drives the slider to move forward inside the slide groove until the anti-slip pad is just in contact with the inner wall of the slide groove, ensuring the stability of the slider inside the slide groove when the OK clamp clamps the workpiece, avoiding positional movement of the slider, and thus ensuring the stability of the OK clamp in the clamping state.

[0014] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0015] The utility model provides a fast clamping fixture for bar-shaped workpieces, such as Figure 1-2 As shown, it includes a base plate 1, a baffle 3 and an OK clamp 5. The OK clamp 5 is unilateral. A card slot 2 is provided on the back of the base plate 1. The baffle 3 can be detachably mounted in the card slot 2. A slide groove 4 is provided at the front end of the base plate 1. A plurality of sliders 6 are slidably connected inside the slide groove 4, and the top surface of the slider 6 is flush with the top surface of the base plate 1. The top surface of each slider 6 is detachably connected with an OK clamp 5. The OK clamp 5 is slidably placed on the top surface of the base plate 1 through the slider 6. The OK clamp 5 is installed on the slider 6, and the slider 6 is slid into the slide groove 4 opened on the base plate 1 to realize the movement of the OK clamp 5 to any position on the top surface of the base plate 1. It can be used for bar workpieces of different sizes, which greatly improves the practicality of the clamping tooling.

[0016] A limiting groove 7 is provided on the back side of the slide 4, and a protrusion 8 is integrated on the back of the slider 6. The protrusion 8 is placed in the limiting groove 7 and is slidably connected to the limiting groove 7. The combination of the limiting groove 7 and the protrusion 8 prevents the slider 6 from tilting up, thereby preventing the OK clip 5 from tilting up when clamping.

[0017] An anti-slip pad 9 is adhered and connected to the front end of the slider 6. The sum of the widths of the anti-slip pad 9 and the slider 6 is smaller than the width of the slide groove 4, so that there is a certain gap between the anti-slip pad 9 and the slide groove 4 or between the slider 6 and the slide groove 4, and the width of the protrusion 8 is larger than the gap.

[0018] When the workpiece is clamped by the OK clamp 5 in cooperation with the baffle 3, the clamping end of the OK clamp 5 contacts and abuts against the workpiece. The abutting force gives the OK clamp 5 a force to move backward, forcing the OK clamp 5 to move backward, thereby causing the OK clamp 5 to drive the slider 6 to move forward inside the slide groove 4 until the anti-slip pad 9 is just in contact with the inner wall of the slide groove 4, ensuring the stability of the slider 6 inside the slide groove 4 when the OK clamp 5 clamps the workpiece, avoiding the slider 6 from moving, and thus ensuring the stability of the OK clamp 5 in the clamping state.

[0019] The top surfaces of the card slot 2 and the baffle 3 are each provided with a plurality of holes corresponding to each other, and the holes are used for assembling the card slot 2 and the baffle 3 by bolt connection.

[0020] The anti-skid pad 9 is made of rubber material. The elastic anti-skid pad 9 can not only improve the anti-skid performance, but also effectively protect the slider 6 and the slide groove 4 from being squeezed and damaged by the force.

[0021] The working principle of the present invention is as follows: the bar-shaped workpiece is placed on one side of the fitting baffle 3. At this time, the OK clamp 5 can be moved according to the length of the workpiece until the OK clamp 5 can be directly pushed. Under the sliding action of the slider 6 and the slide groove 4, the OK clamp 5 is made to move horizontally on the top surface of the base plate 1, so that the number of OK clamps 5 is sufficient to firmly clamp and fix the workpiece. Then, the OK clamp 5 is screwed to clamp the bar workpiece. When screwing, the clamping end of the OK clamp 5 moves backward and contacts the workpiece. When in contact, the clamping end gives the workpiece an abutting force, and at the same time, the workpiece gives the clamping end an opposite force, causing the OK clamp 5 to move backward until the anti-slip pad 9 is close to the slide groove 4 and the OK clamp 5 cannot move. At the same time, the clamping end of the OK clamp 5 only abuts the workpiece.
