Description

Technical Field

[0001] This utility model belongs to the technical field of automotive seat installation equipment, specifically relating to a tray clamping structure. Background Technology

[0002] The use of sliding rails at the bottom of car seats has become a common practice. During the assembly of car seats, the sliding rails need to be fixed before the installation of other components. Currently, the common method for fixing the sliding rails is to directly press them onto the rails using a rotary clamping cylinder. However, because the dimensions of the sliding rails are unstable, they need to be readjusted after each batch change to achieve proper clamping. This readjustment requires production to be stopped, thus reducing production efficiency. Utility Model Content

[0003] This utility model aims to provide a pallet clamping structure that can adapt to clamping different slide rail sizes, reduce debugging time, and thus improve production efficiency.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a pallet clamping structure, including a pallet bottom plate, on which two sets of positioning clamping components corresponding to the slide rail are arranged at intervals on the left and right, and each set of positioning clamping components includes two components arranged at intervals in front and behind, and a driving component is provided in the middle of each set of positioning clamping components for driving the clamping block in the corresponding side positioning clamping component to achieve clamping action, and a conversion component for realizing work conversion is provided between the driving component and each clamping block.

[0005] As a preferred embodiment of the above scheme, each positioning and clamping assembly includes a positioning seat disposed on the bottom plate of the tray. The middle part of the clamping block is hinged to the positioning seat. The middle part of the positioning seat extends forward and backward and is provided with a sliding hole for the clamping rod to pass through. The bottom of the clamping block is hinged to the clamping rod. The other end of the clamping rod passes through the sliding hole and is disposed on the rotating assembly. When the driving assembly is working, it can drive the clamping rod to move back and forth through the rotating assembly. The positioning seat is provided with a positioning pin, which is located between the hinge position of the clamping block and the positioning seat and the corresponding side driving assembly.

[0006] Further preferably, the clamping block is provided with a buffer pad for contacting and protecting the slide rail, the front and rear inner sides of the sliding hole are provided with sliding sleeves for ensuring smooth movement of the clamping rod, and the positioning seat is provided with a limiting block at the position corresponding to the front and rear inner sides of the sliding hole.

[0007] Further preferably, the driving assembly includes a rotating gear and a driving cylinder disposed on the bottom plate of the tray. The telescopic end of the driving cylinder is provided with a movable block that can move left and right. The movable block is provided with a movable rack that extends left and right and meshes with the rotating gear. A vertical rotating shaft is provided in the middle of the rotating gear. The bottom of the rotating shaft is rotatably disposed on a rotating base. The rotating base is U-shaped. A rotating support block for supporting the upper end of the rotating shaft is provided at the upper end of the rotating base.

[0008] In a further preferred embodiment, a movable support block is provided on the side of the rotating base away from the movable block, and the other end of the movable rack is fixed on the movable support block. Two movable guide rods are provided at a distance between the movable block and the movable support block, and each movable guide rod passes through a movable hole provided on two vertical sections of the rotating base. A return spring is provided on the section of the movable guide rod located between the movable block and the rotating base.

[0009] More preferably, the conversion assembly includes a conversion gear, and the front and rear sides of the conversion gear are both provided with conversion racks extending forward and backward. The other end of the conversion rack is connected to the positioning and clamping assembly through a connecting block.

[0010] Further preferably, each positioning and clamping assembly is equipped with an auxiliary positioning and clamping assembly on either the left or right side. The auxiliary positioning and clamping assembly has the same structure as the positioning and clamping assembly. When the driving assembly is working, the clamping block in the auxiliary positioning and clamping assembly can also be clamped by the conversion assembly.

[0011] The beneficial effects of this utility model are as follows: the positioning clamping component clamps the slide rail by setting the drive component and the conversion component. At the same time, the conversion mechanism adopts a gear and rack structure, which can slowly clamp the slide rail during clamping. During long-term use, it can adapt to slide rails with size differences, thereby reducing debugging time and improving production efficiency. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0017] like Figure 1-3 As shown, a pallet clamping structure mainly consists of positioning and clamping components, a drive component, and a pallet base plate 1. Two sets of positioning and clamping components, corresponding to slide rails 2, are spaced apart on the left and right sides of the pallet base plate 1. Each set of positioning and clamping components includes two components spaced apart front and rear, ensuring that each slide rail is clamped from both sides by two positioning and clamping components during clamping. A drive component is located in the middle of each set of positioning and clamping components to drive the clamping blocks 3 in the corresponding side positioning and clamping components to achieve clamping action. That is, the positioning and clamping components on both sides can be clamped by the same drive component, reducing the number of drive components. A conversion component is provided between the drive component and each clamping block to achieve work switching.

[0018] Each positioning and clamping assembly includes a positioning seat 4 mounted on the bottom plate 1 of the pallet. The middle part of the clamping block 3 is hinged to the positioning seat 4. A sliding hole for the clamping rod 5 to pass through is provided in the middle of the positioning seat 4. The bottom of the clamping block 3 is hinged to the clamping rod 5. The other end of the clamping rod 5 passes through the sliding hole and is mounted on the rotating assembly. When the drive assembly is working, the clamping rod can be moved back and forth through the rotating assembly, thereby achieving the clamping of the slide rail.

[0019] To facilitate positioning during slide rail clamping, a positioning pin 6 is provided on the positioning seat 4. The positioning pin 6 is located between the hinge position of the clamping block 3 and the positioning seat 4 and the corresponding side drive assembly. To prevent hard contact during clamping, a buffer pad 7 is provided on the clamping block 3 to contact the slide rail and protect it. To facilitate the sliding of the clamping rod, sliding sleeves are provided on the front and rear inner sides of the sliding hole to ensure smooth movement of the clamping rod. To prevent excessive movement of the clamping rod, a limiting stop 8 is provided on the positioning seat 4 at the front and rear inner positions corresponding to the sliding hole.

[0020] The drive assembly includes a rotating gear 9 and a drive cylinder 10 mounted on the base plate of the tray. A movable block 11, capable of left and right movement, is located at the telescopic end of the drive cylinder 10. A movable rack 12, extending left and right and meshing with the rotating gear, is mounted on the movable block 11. A vertical rotating shaft 13 is located in the middle of the rotating gear 9, and the bottom of the rotating shaft 13 is rotatably mounted on a rotating base 14. Preferably, the rotating base 14 is U-shaped, and a rotating support block 15 for supporting the upper end of the rotating shaft 13 is located at the upper end of the rotating base 14. Bearings are provided between the rotating shaft and the rotating support block, and between the rotating shaft and the rotating base. The drive cylinder drives the movable rack to move, and the meshing of the movable rack with the rotating gear achieves the rotation of the rotating gear.

[0021] To facilitate support at the other end of the moving gear, a moving support block 16 is provided on the side of the rotating base 14 opposite to the moving block 11, and the other end of the moving rack 12 is fixed to the moving support block 16. Two moving guide rods 17 are provided at intervals between the moving block 11 and the moving support block 16, and each moving guide rod 17 passes through the moving holes provided in the two vertical sections of the rotating base. Preferably, moving sleeves are provided on both the left and right sides of the moving holes to ensure smooth movement of the moving guide rods. A return spring 18 is provided on the moving guide rod 17 between the moving block 11 and the rotating base 14 to facilitate return to its original position.

[0022] The conversion assembly includes a conversion gear, with conversion racks 19 extending forward and backward meshing on both the front and rear sides of the conversion gear. The other end of the conversion rack 19 is connected to the positioning and clamping assembly via a connecting block 20, i.e., the connecting block is connected to the clamping rod. In this embodiment, the rotating gear and the conversion gear are the same gear. Of course, the rotating gear and the conversion gear can also be set separately. When set separately, both the rotating gear and the conversion gear are provided with a transmission key between themselves and the rotating shaft. To facilitate the support of one end of the conversion rack, rack support blocks 21 are provided on both the left and right sides of the rotating support block. The rack support blocks are provided with slots for the conversion rack to move forward and backward.

[0023] Ideally, each positioning and clamping assembly should be equipped with an auxiliary positioning and clamping assembly on either side, and the auxiliary positioning and clamping assembly should have the same structure as the positioning and clamping assembly. When the drive assembly is working, the clamping blocks in the auxiliary positioning and clamping assembly can also be clamped through the conversion assembly. By setting up auxiliary clamping assemblies, the entire clamping structure can be adapted to clamp slide rails of different specifications.
