Description

Technical Field

[0001] This utility model relates to sheet metal parts, and more specifically, to a positioning and locking device for body sheet metal parts. Background Technology

[0002] Sheet metal parts are components made by comprehensively cold-working thin metal sheets using sheet metal processing techniques. Their core characteristics include consistent thickness across the entire part, and advantages such as light weight, high strength, strong electrical conductivity, low cost, and good mass production performance. As a fundamental component in industrial manufacturing, sheet metal parts are widely used in the automotive, electronics, communications, medical, and architectural decoration industries, and are an indispensable part of modern industry.

[0003] The technical features of the Chinese patent announcement CN216730259U, which discloses a positioning and switching structure for welded sheet metal parts of a car body, are as follows: it includes a support platform, a support arm, and a positioning component; a bracket is mounted on the support platform; a first cylinder is provided at one end of the support arm, and a mounting seat detachably connected to the positioning component is provided at the other end; a connecting rod that is hinged to the bracket is also provided between the two ends of the support arm.

[0004] In the above technical solution, the positioning component is flipped and stored by rotating the support arm driven by a cylinder.

When the sheet metal parts have significant size differences, the fixture layout needs to be redesigned, resulting in long production line adjustment times.

[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0023] like Figures 1 to 3 As shown, a positioning and locking device for a body sheet metal part includes a fixed platform 1. The fixed platform 1 has four sliding grooves 2, which are symmetrically distributed along the center of the fixed platform 1. Each of the four sliding grooves 2 is provided with a telescopic sleeve plate 3. A set of sliding connecting components is provided on one side of the telescopic sleeve plate 3 on the same side. A sliding drive component is provided on the sliding connecting component. Each telescopic sleeve plate 3 is provided with a telescopic block 4. A set of lifting drive components is provided on each telescopic block 4 on the same side. The telescopic blocks 4 on the same side are fixedly connected by a locking shaft 5. A positioning and locking component is provided on each locking shaft 5. A positioning rod 6 is provided on the top of each positioning and locking component.

[0024] The fixed platform 1 provides support for the whole. During use, it is adjusted according to the overall width of the body sheet metal parts. The sliding drive assembly drives two sets of sliding connection assemblies. The two sets of sliding connection assemblies can drive the telescopic sleeve 3 to move accordingly in the sliding groove 2. Furthermore, the lifting drive assembly can adapt to the height of other equipment, so that various equipment can place the sheet metal parts on the positioning and locking assembly. The positioning and locking assembly can position and clamp the sheet metal parts accordingly through the positioning rod 6.

[0025] Four sliding grooves 2 are symmetrically distributed along the center of the fixed platform 1 to form a stable support structure, which can evenly distribute the stress generated by the sheet metal parts during processing and avoid deformation or displacement caused by unilateral force. The sliding drive assembly controls the horizontal movement of the telescopic sleeve 3 in the sliding groove 2 to achieve rapid adjustment of the positioning position. It can adapt to sheet metal parts of different sizes or shapes without changing the fixture, thus improving the versatility of the equipment. The shrink block can extend and retract in the vertical direction. In conjunction with the lifting drive assembly, it can achieve the height positioning of the sheet metal parts.

[0026] The sliding connection assembly includes two sliding links 7, one end of which is rotatably connected to a sliding joint 8, and the other end is rotatably connected to a sliding drive assembly. Each sliding joint 8 is provided with a sliding base 9, which is respectively located on one side of the telescopic sleeve 3. The sliding drive assembly includes a drive cylinder 10, which is located on one side of the fixed base. The piston rod of the drive cylinder 10 is provided with a drive joint 11, which is rotatably connected to the two sliding links 7.

[0027] The piston rod of the drive cylinder 10 extends or retracts outward, pushing the drive joint 11 to move along the cylinder axis. The drive joint 11 simultaneously pulls the ends of the two sliding connecting rods 7, forming a thrust towards the telescopic sleeve 3. The other end of the sliding connecting rod 7 converts the thrust into a horizontal component through the sliding base 9, pushing the telescopic sleeve 3 to slide along the sliding groove 2 of the fixed platform 1. The two connecting rods are symmetrically arranged on both sides of the drive joint 11, forming a "V" or parallelogram structure to ensure that the telescopic sleeve 3 is subjected to uniform force and avoid jamming or tilting caused by unilateral load. The telescopic sleeve 3 can only move in the horizontal direction within the sliding groove 2. The guiding effect of the sliding groove 2 further ensures the motion accuracy.

[0028] The lifting drive assembly includes a lifting cylinder 12, which is connected to two telescopic sleeve plates 3 on the same side via a lifting seat 13. A lifting connecting plate 14 is provided on the piston rod of the lifting cylinder 12, and two telescopic blocks 4 are connected to the lifting connecting plate 14.

[0029] The piston rod of the lifting cylinder 12 extends upward, pushing the lifting connecting plate 14 to rise vertically. The lifting connecting plate 14 simultaneously drives the two telescopic blocks 4 to move upward. The positioning and locking components on the top of the telescopic blocks 4 move upward accordingly, adjusting to the target height, thereby achieving the height positioning of the sheet metal parts.

[0030] The positioning and locking assembly includes two positioning base plates 15, which are located at both ends of the locking shaft 5. A positioning connecting plate 16 is provided on one side of each of the two positioning base plates 15. Positioning grooves 17 are provided on each of the two positioning connecting plates 16, and positioning slides 18 are slidably connected to each positioning groove 17. Material support plates 19 are bolted to the two positioning slides 18. A locking drive assembly is provided on the material support plate 19, and a positioning rod 6 is located on the top of the material support plate 19. The locking drive assembly includes a locking worm gear 20, with a locking motor 21 connected to one side of the locking worm gear 20. The locking motor 21 is bolted to the material support plate 19 via a locking seat 22. A locking turbine 23 meshes with the locking worm gear 20 and is located on the positioning base plate 15.

[0031] The positioning slide 18 slides within the positioning groove 17 and is fixed to the material tray 19 with bolts, enabling it to move the material tray 19. The locking motor 21 serves as the power source and can drive the locking worm gear 20 to rotate via its output shaft. The locking worm gear 20 meshes with the locking turbine 23, causing the material tray 19 to flip. Simultaneously, it can drive the positioning slide 18 to move within the positioning groove 17. The locking turbine 23 and the locking worm gear 20 cooperate to have a self-locking function, allowing the positioning rod 6 to flip into the precision hole of the sheet metal part for corresponding positioning.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
