Description

Technical Field

[0001] This utility model relates to the field of welding fixture processing for body sheet metal parts, and more particularly to a positioning mechanism moving device. Background Technology

[0002] As people's living standards continue to improve, automobiles have become increasingly popular as a daily means of transportation. Existing automobiles come in a variety of styles and are mainly divided into fuel-powered and new energy-powered vehicles based on their drive system. Although their structural styles and drive systems vary, the main structural types of automobiles are not significantly different, primarily consisting of the body, drive system, suspension, drive wheels, and interior components.

[0003] As the main structure of a car, the car body is the primary load-bearing component for assembling other parts; therefore, the structural strength of the car body is of paramount importance.

[0004] The car body is mainly composed of various sheet metal parts. The existing sheet metal materials include carbon steel, alloy steel, etc. The metal sheets are stamped into the required structural parts by a stamping machine. Then, the corresponding structural parts are assembled and processed by welding, riveting, screwing and other methods to form the sheet metal parts of different parts of the car body. Finally, these sheet metal parts are combined together to form the car body.

[0005] To improve the processing efficiency of body sheet metal parts, body sheet metal parts of the same type are fixed on a special body sheet metal assembly fixture during assembly. The assembled body sheet metal parts are clamped and fixed by clamping and positioning mechanisms such as quick-press clamps and positioning pins, and then connected by welding guns or riveting guns.

[0006] In existing body panel assembly fixtures, quick-press clamps and locating pins are mostly fixed to the fixture's worktable via brackets. These brackets are bolted to the worktable. Some complex body panel parts require clamping and fixing around their entire body before welding or riveting. During clamping, the body panel part is typically clamped vertically first. The clamping and positioning mechanism used to fix its height is fixed in its position on the worktable. Then, a bracket is installed on the worktable around the body panel assembly to connect to a side positioning mechanism. This side positioning mechanism is mounted on the bracket and used to position and fix the body panel around its perimeter. When disassembling the body panel part after processing, the bracket connected to the side positioning mechanism needs to be removed, and then the clamping and positioning mechanism fixing the vertical position of the body panel part needs to be released for easy removal. This process of disassembling and assembling the side positioning device is cumbersome, time-consuming, and inflexible, impacting product processing efficiency. Utility Model Content

A protective plate is fixedly connected to the top of the two symmetrical support seats. The protective plate is mounted above the top of the slider and below the bottom of the connecting plate.

[0011] Furthermore, the bottom of the connecting plate is provided with a front-to-back open spacer groove corresponding to the protective plate.

[0012] Furthermore, the end limiter consists of a limit block and a fixed base; the fixed base is fixed to the base plate by bolts, and the limit block is fixedly connected to the inside of the fixed base, corresponding to the front and back of the end plate of the connecting plate; both the front and back ends of the connecting plate are provided with buffer blocks corresponding to the front and back of the limit blocks of the corresponding end limiter.

[0026] Example 1

[0027] Please refer to the instruction manual attached. Figure 1 and 2 As shown, the instruction manual is attached. Figure 1 and 2 The diagram shows a positioning mechanism moving device of this utility model, used for supporting the positioning mechanism of a body sheet metal part, facilitating the positional movement and adjustment of the positioning mechanism. The positioning mechanism moving device includes a base plate 1. (See attached specification). Figure 1 and 2 As shown, in this embodiment, the base plate 1 has a rectangular structure, with a vertically connected fixing hole 12 at each of its four corners. The fixing holes are preferably countersunk holes, through which T-bolts can be fixedly connected to the workbench of the body sheet metal assembly fixture. In actual use, the top surface of the base plate 1 can be horizontal or inclined, facilitating the installation of positioning mechanisms such as quick-press clamps with different clamping requirements. A connecting plate 2 is provided on the top surface of the base plate 1, and the connecting plate 2 is parallel to the top surface of the base plate 1. In this embodiment, the connecting plate 2 has a rectangular structure for convenience. The bracket for mounting the positioning mechanism is provided on the connecting plate 2, which has several connecting holes 24 for easy installation of the positioning mechanism. These connecting holes 24 are typically arranged in a rectangular array on the top of the connecting plate 2 to facilitate the connection of different brackets. The connecting holes 24 are threaded holes, allowing the brackets to be fixedly connected to the corresponding connecting holes 24 with bolts. The connecting plate 2 and the base plate 1 are connected by a guide mechanism 4 for back-and-forth movement. To ensure the stability of the connecting plate 2's back-and-forth movement on the base plate 1, please refer to the appendix of the instruction manual. Figures 1 to 3 As shown, the guide mechanism 4 has two sets, symmetrically arranged at the bottom of the connecting plate 2 near the left and right sides; see the appendix of the specification. Figure 3 and 5As shown, the guiding mechanism 4 consists of a slide rail 41 and a slider 42. The slide rail 41 is a linear guide rail, which is longitudinally fixed to the top of the base plate 1 by bolts. The slider 42 slides in conjunction with the slide rail 41. The connecting plate 2 is fixedly connected to the top of the slider 42 by bolts. To prevent dust or welding slag from falling on the slide rail 41 and affecting the smoothness of the slider 42's back-and-forth movement on the slide rail 41, a protective plate 43 is provided above the top of the slider 42. The length and width of the protective plate 43 are slightly larger than the length and width of the slide rail 41. For convenient installation of the anti-slip plate 43, please refer to the appendix of the instruction manual. Figure 5 As shown, a support base 44 is provided at each of the front and rear ends of the slide rail 41. The support base 44 is fixedly installed on the base plate 1 by bolts. The two support bases 44 at the front and rear ends of the slide rail 41 are symmetrical. The top height of the support base 44 is higher than the top height of the slider 42 on the slide rail 41. A protective plate 43 is fixedly connected to the top of the two symmetrical support bases 44. The anti-slip plate 43 is fixedly connected to the support base 44 by screws, which is convenient for disassembly and assembly. The protective plate 43 is mounted above the top of the slider 42 and below the bottom of the connecting plate 2, without interfering with each other. It should be noted that, for the convenience of connecting plate 2 and slider 42, please refer to the appendix of the instruction manual. Figure 5 As shown, the width of the slider 42 is greater than the width of the protective plate 43. The connecting plate 2 is threadedly connected to the part of the slider 42 that protrudes from the outside of the protective plate 43 by bolts. To avoid friction between the bottom of the connecting plate 2 and the top of the protective plate 43, which would interfere with the forward and backward movement of the connecting plate 2, please refer to the appendix of the instruction manual. Figure 3 and 4 As shown, the bottom of the connecting plate 2, corresponding to the protective plate 43, is provided with a front-to-back communicating clearance groove 22, and the clearance groove 22 and the protective plate 43 are fitted with a clearance fit; in order to drive the connecting plate 2 to move back and forth on the base plate 1, a cylinder 3 for driving the connecting plate 2 to move back and forth is fixed at the center of the rear end of the base plate 1, and the piston rod end of the cylinder 3 is connected to the center of the back side of the connecting plate 2, and the cylinder 3 drives the connecting plate 2 to move back and forth on the base plate 1 through its piston rod; for easier piston rod driving of the connecting plate 2, please refer to the appendix of the instruction manual. Figure 1 , 2As shown in Figure 4, a hinge seat 21 is fixedly connected to the rear center of the connecting plate 2. The hinge seat 21 and the connecting plate 2 are fixedly connected by bolts, making disassembly and assembly convenient. A hinge joint 31 is fixedly connected to the piston rod end of the cylinder 3. The hinge joint 31 and the piston rod end are threaded together, facilitating disassembly and assembly. The hinge joint 31 and the hinge seat 21 are movably connected by a pin, ensuring that the cylinder 3 can drive the connecting plate 2 to move smoothly back and forth linearly on the slide rail 41 even when the center of the piston rod end of the cylinder 3 and the center of the end of the connecting plate 2 are not at the same horizontal position. To limit the forward and backward movement distance of the connecting plate 2, at least two sets of symmetrical end limiters are provided on the base plate 1. The two sets of end limiters are respectively close to the front and rear ends of the base plate 1. The connecting plate 2 is located between the two sets of end limiters. In this embodiment, there are four sets of end limiters, arranged symmetrically in pairs, and the four sets of end limiters correspond to the four corners of the front and rear ends of the connecting plate 2. See Appendix of the specification. Figure 6 As shown, the end limiter consists of a limit block 11 and a fixing base 111; refer to the appendix of the instruction manual. Figure 1 and 2 As shown, the fixed base 111 has an L-shaped structure, and its horizontal part is fixed to the base plate 1 by bolts. The limiting block 11 is fixedly connected to the inner side of the vertical part of the fixed base 111, and the limiting block 11 on the fixed base 111 corresponds to the front and back of the end face of the connecting plate 2. In order to avoid the connecting plate 2 from being damaged by impact with the limiting block 11, buffer blocks 23 are provided at both the front and back ends of the connecting plate 2, which correspond to the front and back of the limiting block 11 of the corresponding end limiters. It should be noted that the buffer blocks 23 and the limiting blocks 11 are both made of rubber and have a certain buffering effect. In order to improve the safety of the connecting plate 2 moving back and forth, and to avoid the connecting plate 2 being subjected to the force of movement due to the cylinder 3 not stopping when it comes into contact with the limiting block 11, please refer to the appendix of the instruction manual. Figure 1 and 2 As shown, the base plate 1 is provided with limit switches 5. There are two sets of limit switches 5, which are symmetrically arranged on the base plate 1 near the front and rear ends. The connecting plate 2 is located between the two sets of limit switches 5. In this embodiment, the front-to-back distance between the two sets of limit switches 5 is not greater than the distance between the two corresponding limit blocks 11. The limit switches 5 and the cylinder 3 are both electrically connected to the position PLC controller. When the end face of the connecting plate 2 touches any set of limit switches 5, the cylinder 3 is controlled to stop, thereby controlling the connecting plate 2 to stop moving, thus improving the safety of the front-to-back movement of the connecting plate 2.

[0028] During operation, the base plate 1 is bolted to the workbench of the body sheet metal assembly fixture. A bracket is bolted to the preset position of the connecting plate 2 on the base plate. The bracket is equipped with a positioning mechanism for clamping or positioning the body sheet metal parts. In use, the body sheet metal parts are placed on the support mechanism of the body sheet metal assembly fixture. Then, the connecting plate 2 is moved towards the body sheet metal parts by the cylinder 3. The movement stops when the positioning mechanism on the connecting plate 2 reaches the designated position. The positioning mechanism on the connecting plate 2 then further positions and clamps the body sheet metal parts. Preferably, the positioning mechanism is positioned and fixed on the side of the body sheet metal parts. When disassembling the body sheet metal parts after processing, the positioning mechanism is first released. Then, the connecting plate 2 is moved away from the body sheet metal parts by the cylinder 3. After the positioning mechanism on the connecting plate 2 separates from the body sheet metal parts, the body sheet metal parts can be easily removed from the support mechanism of the body sheet metal assembly fixture without needing to remove the positioning mechanism from the workbench of the body sheet metal assembly fixture. This facilitates the installation and disassembly of the body sheet metal parts and makes operation convenient and simple.

[0029] This positioning mechanism has a simple structure. The connecting plate 2 can be driven by the cylinder 3 to move linearly. Its position can be flexibly adjusted on the workbench of the body sheet metal assembly fixture. The bracket seat connecting the positioning mechanism is fixedly installed on the connecting plate 2. The position of its top positioning mechanism can be flexibly adjusted by moving the connecting plate 2, which facilitates the clamping, fixing and disassembling of body sheet metal parts. It is flexible in operation, simple to use, and highly versatile, thus improving the processing efficiency of body sheet metal parts.

[0030] It should be emphasized that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
