Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a double-arm clamp that allows for flexible adjustment of the clamping angle. Background Technology

[0002] Fixture: A device used in mechanical manufacturing to fix an object being processed in the correct position for construction or inspection.

[0003] However, in the existing technology, existing mechanical structures generally use multi-axis robotic arms to rotate and move the gripper when clamping parts. This can meet the needs of clamping in different positions and areas. However, the operation and maintenance of multi-axis robotic arms require a high level of technical expertise, and cannot achieve the effect of cost reduction and efficiency improvement. Utility Model Content

[0004] This invention provides a dual-arm gripper with a flexible adjustable gripping angle, which solves the structural technical problem of the multi-axis robotic arm mentioned above, which requires a high level of technical expertise for operation and maintenance and cannot achieve cost reduction and efficiency improvement.

[0005] The present invention provides the following solution to the above-mentioned technical problems: A double-arm clamp with flexible adjustable clamping angle, comprising a mounting base plate, a rotating seat mechanism on the top of the mounting base plate, a support column on the top of the rotating seat mechanism, an arc-shaped groove on the top of the support column, a speed-regulating motor on the inner bottom surface of the arc-shaped groove, two crossbars fixed on one side of the support column, a fixing plate fixed between one side of each crossbar, two sliding columns fixed on one side of the fixing plate, a sliding block slidably connected to the outer wall of each sliding column, a bearing fixed at the center of one side of the fixing plate, a bidirectional lead screw body connected to one side of the bearing, two lead screw nut blocks slidably connected to the outer wall of the bidirectional lead screw body, a first horizontal plate fixed on one side of each lead screw nut block, a second horizontal plate fixed on the other side of each lead screw nut block, and an angle-adjusting clamping assembly between the bottoms of each second horizontal plate.

[0006] The beneficial effects of this utility model are as follows: The mounting base plate mainly serves to facilitate the support of the rotating seat mechanism, which is composed of a drive motor and rotating components. This allows the support column to rotate, and the support column allows the arc groove to support the first speed-regulating motor. The first speed-regulating motor can drive the bidirectional lead screw to rotate. The crossbar can support the fixed plate, and the fixed plate can support the sliding column. The sliding column allows the sliding block to move laterally repeatedly. The first bearing facilitates the rotation of the bidirectional lead screw. The spacing between the two lead screw nut blocks can be changed, allowing the angle adjustment clamping assembly to move laterally repeatedly. Both the first and second horizontal plates serve to provide support.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the angle-adjustable clamping assembly includes two frame bodies, which are disposed at the bottom of the two second horizontal plates, and a support plate is fixed on one side of each frame body.

[0009] The beneficial effects of adopting the above-mentioned further solution are: the frame body can easily fix the support plate, and the support plate can support the No. 2 speed-regulating motor.

[0010] Furthermore, a second speed-regulating motor is provided on the top of each of the support plates, and a second bearing is provided on both sides of the interior of each of the frame bodies.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the No. 2 speed-regulating motor can rotate the rotating column on the No. 2 bearing, and the No. 2 shaft can be connected to the rotating column.

[0012] Furthermore, the output shaft of each of the second speed-regulating motors is connected to a rotating column, and the outer wall of each rotating column is provided with a rotating body.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the rotating column can support the rotating column body, and the rotating column body can support the V-shaped bracket.

[0014] Furthermore, a V-shaped bracket is provided at the bottom of each of the rotating cylinders.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the V-shaped bracket can facilitate the support of the hydraulic telescopic rod.

[0016] Furthermore, each of the V-shaped brackets is provided with a hydraulic telescopic rod on both sides, and a push plate is provided at the bottom of each of the four hydraulic telescopic rods.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the hydraulic telescopic rod can move laterally and repeatedly with the push plate, which can clamp and pick up the parts.

[0018] Beneficial effects: The No. 1 speed-regulating motor can rotate the bidirectional lead screw, which can change the distance between the two lead screw nut blocks. This makes it easier to adjust and move the angle-adjusting gripping component laterally. The angle-adjusting gripping component can be used to rotate and grip, which can replace the multi-axis robotic arm for rotational angle movement and gripping. The operation and maintenance of the multi-axis robotic arm does not require a high level of technical expertise, thus reducing costs and increasing efficiency as much as possible.

[0026] The following is in conjunction with the appendix Figure 1-3 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0027] Example 1

[0028] like Figure 1-3As shown, this utility model discloses a double-arm clamp with a flexible adjustable clamping angle, including a mounting base plate 1. A rotating seat mechanism 2 is provided on the top of the mounting base plate 1. A support column 3 is provided on the top of the rotating seat mechanism 2. An arc-shaped groove 4 is provided on the top of the support column 3. A speed-regulating motor 5 is provided on the inner bottom surface of the arc-shaped groove 4. Two crossbars 6 are fixed on one side of the support column 3. A fixing plate 7 is fixed between one side of each crossbar 6. Two sliding columns 8 are fixed on one side of the fixing plate 7. A sliding block 9 is slidably connected to the outer wall of each sliding column 8. A bearing 10 is fixed at the center of one side of the fixing plate 7. A bidirectional lead screw body 11 is connected to one side of the bearing 10. Two lead screw nut blocks 12 are slidably connected to the outer wall of the bidirectional lead screw body 11. A first horizontal plate 13 is fixed on one side of each lead screw nut block 12. A second horizontal plate 14 is fixed on the other side of each second horizontal plate 14. An angle-adjusting clamping assembly 15 is provided between the bottoms of each second horizontal plate 14.

[0029] Example 2

[0030] like Figure 1-3 As shown, the angle adjustment clamping assembly 15 includes two frame bodies 151, which are located at the bottom of two second horizontal plates 14. A support plate 152 is fixed on one side of each frame body 151. A second speed-regulating motor 153 is installed on the top of each support plate 152. A second bearing 154 is installed on both sides inside each frame body 151. The output shaft of each second speed-regulating motor 153 is connected to a rotating column 155. A rotating column body 156 is installed on the outer wall of each rotating column 155.

[0031] In this embodiment, the frame 151 can facilitate the fixing of the support plate 152, the support plate 152 can support the second speed-regulating motor 153, the second speed-regulating motor 153 can rotate the rotating column 155 on the second bearing 154, the second shaft can be connected to the rotating column 155, the rotating column 155 can support the rotating column 156, and the rotating column 156 can support the V-shaped bracket 157.

[0032] Example 3

[0033] like Figure 1-3 As shown, each rotating column 156 has a V-shaped bracket 157 at its bottom, and each V-shaped bracket 157 has a hydraulic telescopic rod 158 on both sides. Each of the four hydraulic telescopic rods 158 has a push plate 159 at its bottom.

[0034] In this embodiment, the V-shaped bracket 157 can easily support the hydraulic telescopic rod 158, which can move laterally and repeatedly with the push plate 159, thus clamping and picking up the parts.

[0035] Working principle:

[0036] When clamping and moving are required, the rotating seat mechanism 2 allows the support column 3 to rotate. The sliding column 8, sliding block 9, and first and second horizontal plates 13 and 14 assist the two lead screw nut blocks 12 in changing their spacing and moving laterally on the bidirectional lead screw body 11. This allows the angle-adjusting clamping assembly 15 to move. The angle-adjusting clamping assembly 15, through the second speed-regulating motor 153, can rotate the rotating column 155 and rotating column body 156 by an angle. Controlling their rotation allows the double-arm clamp to rotate. The hydraulic telescopic rod 158 and push plate 159 on the double-arm clamp then clamp the part. This can replace a multi-axis robotic arm for rotational angle movement and clamping. Without the need for a high level of technical expertise in the operation and maintenance of a multi-axis robotic arm, this method can reduce costs and increase efficiency as much as possible.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
