A clamp support press structure in the form of a non-counter-pressure

Abstract

This utility model discloses a non-pressing type clamp support clamping structure, including a base plate (1). The clamping structure is divided into a pressure block (2) and a support block (3) located on both sides of the base plate (1). The pressure block (2) is attached to the upper surface of the base plate (1), and the support block (3) is attached to the lower surface of the base plate (1). The contact point between the pressure block (2) and the base plate (1) and the contact point between the support block (3) and the base plate (1) are not on the same vertical line. In this way, the support point of the pressure block (2) and the support point of the support block (3) are in different positions.

Description

Technical Field

[0001] This utility model belongs to the field of body processing technology. Specifically, this utility model relates to a non-pressing type clamp support clamping structure. Background Technology

[0002] Automotive body structure: In the assembly process of automotive parts, a challenge in manufacturing the misalignment between the inner A-pillar sill edge of the door opening and the outer side panel is the assembly of the door opening inner panel and the outer side panel. This is mainly because the assembly of the door opening inner panel sill edge and the outer side panel involves various irregular overlapping surfaces, while the outer panel is an integral drawn and formed appearance surface, and a narrow closed cavity is formed between the inner and outer panels. The appearance surface lacks relevant reference feature holes, feature surfaces, etc., which can be used for design positioning, support, and clamping. Due to the special structure of the A-pillar of the side panel assembly, it is also impossible to pass through the appearance surface, the side panel reinforcement, or through the narrow closed cavity to precisely control the inner side panel.

[0003] A patent application with patent number 202310003345.1, published on May 9, 2023, discloses a tooling structure for an outer side panel of an automobile, including a left-end clamping mechanism, a right-end clamping mechanism, and a rear-end clamping mechanism. The left-end clamping mechanism and the right-end clamping mechanism have the same structure and are symmetrically arranged. A rear-end clamping mechanism is provided at one end of each of the left-end clamping mechanism and the right-end clamping mechanism. This utility model utilizes the configuration of the left-end clamping mechanism, the right-end clamping mechanism, and the rear-end clamping mechanism... The mechanism includes a left-end clamping mechanism and a right-end clamping mechanism, where the first moving component pushes the first clamping component to move to both ends of the vehicle side panel and contact them. The first clamping components in the left-end clamping mechanism and the right-end clamping mechanism clamp the vehicle side panel, thereby clamping and fixing both ends of the vehicle side panel. The rear-end clamping mechanism clamps the upper edge of the vehicle side panel, thereby clamping and fixing one side of the vehicle side panel, thus improving the clamping firmness.

[0004] During assembly, the front assembly of the left / right side inner panel is typically larger than 1500mm and close to 2000mm. This component is assembled on the outer side panel and the side reinforcement. Due to the excessive length of the component, and the fact that the outer side panel and the side reinforcement cannot provide a penetrable or perforated position in the middle for precise control of the component's assembly position, the fixture design usually uses the front and rear ends of the component as the reference surface for supporting and clamping the component. This is combined with the component's positioning reference holes and the fixture's positioning pins to achieve the assembly, positioning, and clamping of the component. Due to the special shape of the side A-pillar (the edge of the door opening is not parallel to the edge of the windshield opening), the common support and clamping method cannot ensure that the edges of the left / right side A-pillars are flush. This leads to a series of welding strength and weld quality issues. Utility Model Content

[0005] The present invention aims to provide a non-pressurized clamping structure for stable clamping and improved welding effect.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a non-pressing type clamp support clamping structure, including a base plate, the clamping structure is divided into a pressing block and a support block located on both sides of the base plate, the pressing block is attached to the upper surface of the base plate, the support block is attached to the lower surface of the base plate, and the contact point between the pressing block and the base plate and the contact point between the support block and the base plate are not on the same vertical line.

[0007] The clamping structure also includes an L-shaped base, the top of which is provided with a connector that is connected to the clamping block.

[0008] The L-shaped base is equipped with a square cylinder, the connecting member is a connecting arm located at the output end of the square cylinder, the pressure block is located at the end of the connecting arm, and the connecting arm is located above the top of the L-shaped base.

[0009] The connecting arm is provided with a limiting block, which is a vertical T-shaped block and is located above the L-shaped base.

[0010] The connecting arm has a top plate at one end, and the pressure block is located at one end of the top plate.

[0011] A circular cylinder is provided on the side of the top plate away from the connecting arm. A connecting block is provided at the output end of the circular cylinder, and a support block is provided on the connecting block.

[0012] The pressure block is U-shaped, and the support block is claw-shaped.

[0013] The side of the pressure block closest to the substrate is a horizontal plane.

[0014] The technical effect of this utility model is that by changing the position of the support point, the component is subjected to pressure and the supporting force and rotational torque of the support point, making the lap joint surface of the inner side panel adjustable. This allows the lap edge to be adjusted to a flush state, which is beneficial for controlling welding strength and weld quality. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0021] Please see Figure 1-3 A non-pressing clamp support clamping structure includes a base plate 1. The clamping structure is divided into a pressing block 2 and a support block 3 located on both sides of the base plate 1. The pressing block 2 is attached to the upper surface of the base plate 1, and the support block 3 is attached to the lower surface of the base plate 1. The contact point between the pressing block 2 and the base plate 1 and the contact point between the support block 3 and the base plate 1 are not on the same vertical line. A circular cylinder 9 is provided on the side of the top plate 8 away from the connecting arm 6. A connecting block 10 is provided at the output end of the circular cylinder 9. The support block 3 is set on the connecting block 10. The pressing block 2 is U-shaped, and the support block 3 is claw-shaped.

[0022] The support points of pressure block 2 and support block 3 are located at different positions. By changing the position of the support points, the components are subjected to pressure, support force, and rotational torque, making the lap joint surface of the inner side panel adjustable. This allows the lap edge to be adjusted to a flush state, which is beneficial for welding strength and weld quality control. This improves the flushness of the lap joint between the inner side panel and the side reinforcement plate and outer side panel, increases the weld strength of the lap edge, and reduces weld defects such as half-points, burrs, and spatter. It also reduces the cost of grinding, rework, and auxiliary materials and tools due to unevenness, misalignment, half-points, and burrs on the welded edge. Furthermore, the overall structure is simple, the manufacturing cost is low, and it is convenient to modify / install / debug, with strong applicability and easy to popularize. The lifting and lowering of support block 3 is controlled independently by a circular cylinder 9. When the base plate 1 is placed between support block 3 and pressure block 2, the pressure block is controlled by a square cylinder 5. The support block 2 and the support block 3 descend as a whole, allowing the pressure block 2 to press against the upper surface of the substrate 1. The circular cylinder 9 controls the support block 3 to rise, clamping the substrate 1 from both the top and bottom. Since the support points of the substrate 1 are different and misaligned, the components are subjected to pressure, support force, and rotational torque of the support points, making the lap joint surface of the inner side panel adjustable. This allows the lap edge to be adjusted to a flush state, which is beneficial for welding strength and weld quality control. The U-shaped pressure block 2 can raise the top plate 8 connected to the pressure block 2, so that the top plate 8 will not contact the substrate 1 when the pressure block 2 is pressed down, avoiding the top plate 8 affecting the clamping of the substrate 1. The claw-shaped support block 3 has a certain slope, so the support points of the substrate 1 and the support block 3 can move along the slope surface of the support block 3 as the support block 3 rises and falls, making it easy to adjust the angle of the substrate 1 and make the lap edge flush.

[0023] The clamping structure also includes an L-shaped base 4, the top of which is provided with a connector for the pressure block 2; the L-shaped base 4 is installed on a base such as a platform to support the overall structure, and the connector is used to install the pressure block 2 on the L-shaped base 4.

[0024] The L-shaped base 4 is equipped with a square cylinder 5, and the connecting component is a connecting arm 6 located at the output end of the square cylinder 5. The pressure block 2 is located at the end of the connecting arm 6, and the connecting arm 6 is located above the top of the L-shaped base 4. The square cylinder 5 drives the entire connecting arm 6 and the pressure block 2 located on the connecting arm 6, thereby driving the pressure block 2 to press on the substrate 1, pressing the substrate 1 and fixing the substrate 1 in conjunction with the support block 3.

[0025] The connecting arm 6 is provided with a limiting block 7, which is a vertical T-shaped block and is located above the L-shaped base 4. The limiting block 7 is used to limit the descent of the connecting arm 6 to avoid excessive descent and breakage of the substrate 1.

[0026] The end of the connecting arm 6 is provided with a top plate 8, and the pressure block 2 is set at one end of the top plate 8; the top plate 8 is used to increase the area of ​​the structure that can be installed, making it convenient to add equipment and auxiliary workpieces.

[0027] The side of the pressure block 2 closest to the substrate 1 is horizontal; this makes the downward pressure more stable.

[0028] The technical effect of this utility model is that by changing the position of the support point, the parts are subjected to pressure and the supporting force and rotational torque of the support point, so that the lap joint surface of the inner side panel stop is adjustable, thereby adjusting the stop edge to a flush state, which is beneficial to the control of welding strength and weld quality.

[0029] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
