[0031] The first screw 405 in the sliding assembly 4 is rotated, so that the moving link 406 can move close to the fixed seat 404, at this time, the angle between the two sliding connecting arms 407 is increased, the two sliding contact seats 408 are pushed away from each other, the connecting booms 409 are also pushed away from each other under the drive of the sliding contact seats 408, and an included angle is formed between the sliding connecting arms 407 and the sliding contact seats 408, since the sliding contact seats 408 and the connecting booms 409 are rotatably connected, the connecting booms 409 always remain in a horizontal state.

[0032] Therefore, without replacing other clamps, different parts of hardware or other hardware can be clamped and fixed, the positioning and assembly errors are reduced, and the machining quality of the hardware is improved.

[0033] Refer to Figure 1 , Figure 5 and Figure 6, the side close to each other of the extension assembly 4 is provided with a clamp assembly 5, the clamp assembly 5 is provided with four groups, and every two groups of clamp assemblies 5 are provided with the same vertical axis, the clamp assembly 5 further comprises a first connecting arm 504, the first connecting arm 504 is symmetrically and rotatably arranged on one side of a bearing clamp table 501, one side of the bearing clamp table 501 is fixedly provided with a force spring 503, the other end of the first connecting arm 504 is rotatably provided with a second connecting arm 505, the other end of the second connecting arm 505 is rotatably provided with a bearing connecting plate 506, the bearing connecting plate 506 is fixedly arranged on the other end of the force spring 503, and the other side of the bearing connecting plate 506 is slidably provided with a fixed frame plate 507.

[0034] When the connecting arms 409 are away from each other, the two groups of clamp assemblies 5 are simultaneously away from each other, the bearing clamp table 501 and the contact clamp shell 502 in the clamp assembly 5 move towards the sliding rail 402 due to the state change of the sliding seat 408 and the connecting arms 409, and the angle between the first connecting arm 504 and the second connecting arm 505 in the clamp assembly 5 gradually decreases, and the force spring 503 is compressed, so as to adapt to the state change of the bearing clamp table 501 and the contact clamp shell 502, and make the connection between the bearing clamp table 501 and the bearing connecting plate 506 more stable.

[0035] And the outer side of the contact clamp shell 502 is provided with anti-skid lines, the anti-skid lines are arranged in a curve, so as to prevent the clamped hardware from sliding, and further improve the stability of the contact clamp shell 502 when clamping the hardware

[0036] The connecting arms 409 are slidably arranged at the top end of the bearing connecting plate 506, the inner side of the sliding rail 402 is fixedly provided with a fixed seat 404, and the fixed seat 404 is detachably arranged on the inner side of the fixed frame plate 507.

[0037] In this way, when the height of the connecting arms 409 changes, the connecting arms 409 are still in a horizontal state, so as to conveniently drive the bearing clamp table 501 to change position synchronously.

[0038] Referring to Figure 1 and Figure 4 The top end of the workbench 1 is symmetrically and rotatably provided with an adjusting screw shell 3, the inner side of the adjusting screw shell 3 is threadedly connected with a driving displacement screw 301, one end of the driving displacement screw 301 is fixedly provided with a moving seat 302, one side of the top end of the moving seat 302 is fixedly provided with a bearing connecting frame 303, the bearing connecting frame 303 is detachably arranged on one side of the reinforcing vertical plate 401, and the moving seat 302 is slidably arranged on the top end of the workbench 1.

[0039] The rotation of the adjusting screw shell 3 drives the displacement screw 301 to move and the moving abutment 302 to move, so that the moving abutments 302 on both sides move close to each other, thereby driving the expansion assembly 4, the clamp assembly 5 and the auxiliary clamp structure 6 to move, and clamping and fixing the hardware through the contact clamp shell 502 and the contact clamp table 601.

[0040] Referring to Figure 1 and Figure 7 , the auxiliary clamp structure 6 is arranged outside the sliding track 402, and the auxiliary clamp structure 6 comprises a contact clamp table 601 arranged between the two bearing clamp tables 501 arranged along the vertical axis, one side of the contact clamp table 601 is fixedly provided with a horizontal displacement screw shell 602, the inside of the horizontal displacement screw shell 602 is threadedly connected with a second screw rod 603, the second screw rod 603 is fixedly arranged at one end of the first screw rod 405, the second screw rod 603 is rotatably arranged at one side of the fixed abutment 404, and the outside of the horizontal displacement screw shell 602 is symmetrically and slidably connected with a fixed guide rail 604 which is detachably arranged on the inside of the fixed frame plate 507.

[0041] When the first screw rod 405 rotates, the second screw rod 603 in the auxiliary clamp structure 6 will also rotate, and the rotation of the second screw rod 603 causes the horizontal displacement screw shell 602 to gradually approach the sliding track 402, so that the contact clamp table 601 is driven to move, and the speed of the contact clamp table 601 approaching the sliding track 402 is greater than the speed of the bearing clamp table 501 approaching the sliding track 402, so that the same side of the bearing clamp table 501 and the contact clamp table 601 can form a curve during adjustment, facilitating clamping and fixing of cylindrical hardware or cylindrical parts.

[0042] Embodiment two: referring to Figure 2 and Figure 3 , the top end of the workbench 1 is provided with a notch, the top end of the notch is provided with a lifting support 2, the bottom end of the lifting support 2 is provided with inclined surfaces on both sides, the bottom end of the inclined surfaces is provided with a sliding track, the bottom end of the lifting support 2 is slidably provided with a moving top table 202 on both sides, the side of the moving top table 202 close to each other is rotatably provided with an adjusting screw rod 203, the adjusting screw rods 203 are fixedly connected with a drive gear 204, the outside of the drive gear 204 is meshingly provided with a drive toothed plate 205, the bottom end of the drive toothed plate 205 is fixedly connected with an electric telescopic rod 207 through a connecting table 206, the electric telescopic rod 207 is fixedly arranged at the bottom end of the workbench 1, one side of the workbench 1 is fixedly provided with a control panel 101, and the control panel 101 is electrically connected with the electric telescopic rod 207.

[0043] When clamping the hardware, the height of the lifting support 2 can be adjusted according to the size of the hardware. If the hardware is small in size, the lifting support 2 is raised, and vice versa. When the lifting support 2 is lowered, the electric telescopic rod 207 is controlled to be shortened through the control panel 101, so that the connecting table 206 can drive the driving tooth plate 205 to move, and the driving gear 204 can be driven to rotate. The rotation of the driving gear 204 drives the two adjusting screws 203 to rotate, so that the moving top table 202 can move away from each other, so that the lifting support 2 can be lowered and slowly enter the gap, and the support piece carrying table 201 can be lowered synchronously. The position of the support piece carrying table 201 is the center point between the clamp assemblies 5, so that the clamp assemblies 5 on both sides can clamp the hardware on the top of the support piece carrying table 201. According to the shape of the hardware, the support piece carrying table 201 of different shapes can be replaced to lift the hardware.

[0044] It should be noted that the top end of the lifting support 2 is detachably provided with the support piece carrying table 201, the end surface of the moving top table 202 in contact with the lifting support 2 is provided with a sliding groove, the moving top table 202 penetrates and is slidably arranged at the top end of the workbench 1, and the outer sides of the adjusting screws 203 are rotatably provided with the fixed hanging plates 208, which are fixedly arranged at the bottom end of the workbench 1.

[0045] According to the shape of the hardware, the support piece carrying table 201 of different shapes can be replaced to lift the hardware, so as to achieve more stable clamping effect.

[0046] Working principle: when clamping the square part of the hardware, the clamp is adjusted to the state shown in the figure, and the contact piece clamping shell 502 and the contact piece clamping table 601 on both sides are arranged on the same vertical axis, so as to clamp and fix the square part.

[0047] When the cylindrical part or the cylindrical hardware needs to be clamped, the first screw rod 405 in the expansion assembly 4 is rotated, so that the moving link 406 can move close to the fixed seat 404, at this time the angle between the two expansion connecting arms 407 will increase, and the two sliding seats 408 will be pushed away from each other, and the connecting arms 409 will also be driven by the sliding seats 408 to move away from each other, and at the same time, an angle will be formed between the expansion connecting arms 407 and the sliding seats 408. Since the sliding seats 408 and the connecting arms 409 are rotationally connected, the connecting arms 409 will always remain horizontal, and the two sets of clamp assemblies 5 will be driven away from each other. The load clamp table 501 and the contact clamp shell 502 in the clamp assembly 5 will move close to the sliding rail 402 due to the change in the state of the sliding seat 408 and the connecting arm 409, and the angle between the first connecting arm 504 and the second connecting arm 505 in the clamp assembly 5 will gradually decrease, and the force spring 503 will be compressed, thereby adapting to the change in the state of the load clamp table 501 and the contact clamp shell 502, and making the connection between the load clamp table 501 and the receiving web 506 more stable.

[0048] It should be noted that the change in the state of the connecting arm 409 will move at the top end of the receiving web 506, so that the receiving web 506 can be moved together when the connecting arm 409 moves up and down.

[0049] The first screw rod 405 will also rotate the second screw rod 603 in the auxiliary clamp structure 6 at the same time, and the rotation of the second screw rod 603 will make the horizontal moving screw shell 602 gradually close to the sliding rail 402, so that the contact clamp table 601 will be moved. The speed of the contact clamp table 601 close to the sliding rail 402 is greater than the speed of the load clamp table 501 close to the sliding rail 402, so that the same side of the load clamp table 501 and the contact clamp table 601 can form a curve when adjusting, which is convenient for clamping and fixing the cylindrical hardware or the cylindrical part, and the clamp assembly 5 on the other side can also be adjusted by the same operation method.

[0050] After the adjustment is completed, the height of the lifting table 2 is adjusted according to the size of the hardware, if the size of the hardware is small, the lifting table 2 is raised, otherwise, the lifting table 2 is lowered, when the lifting table 2 is lowered, the electric telescopic rod 207 is controlled to be shortened through the control panel 101, so that the connecting table 206 can drive the driving gear plate 205 to move, and the driving gear 204 can be driven to rotate, the rotation of the driving gear 204 drives the two adjusting screws 203 to rotate, so that the moving top table 202 can move away from each other, so that the lifting table 2 can be lowered and slowly enter the gap, and the supporting table 201 can be lowered synchronously, the position of the supporting table 201 is the center point between the clamp assemblies 5, so that the clamp assemblies 5 on both sides can clamp the hardware on the top of the supporting table 201, according to the shape of the hardware, different shapes of the supporting table 201 can be replaced to lift the hardware, so as to achieve more stable clamping effect and improve the welding processing quality;

[0051] When the clamping work is carried out, the adjusting nut 3 is rotated, the driving screw 301 can be moved, and the moving connecting table 302 is moved together, so that the two moving connecting tables 302 are close to each other, so as to drive the expansion assembly 4, the clamp assembly 5 and the auxiliary clamp structure 6 to move together, and the hardware is clamped and fixed through the contact clamp shell 502 and the contact clamp table 601, so that the hardware with different shape parts does not need to replace other clamps, the positioning error and assembly error are reduced, and the processing quality is improved.

[0052] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
