Description

Technical Field

[0001] This utility model relates to the field of automotive parts inspection tools, and in particular to a clamping device with adjustable height. Background Technology

[0002] In automotive parts inspection brackets, quick-release clamps are typically used to clamp and secure the workpiece to be inspected. When using the same inspection bracket to inspect both individual parts and assemblies, the thickness of the material increases due to welding of the assemblies. Therefore, it is usually necessary to manually adjust the pressing position of the pressure head by manually tightening the two limit nuts screwed onto the pressure head connecting rod.

[0003] However, due to the large number of quick-clamps on the inspection bracket, manually adjusting the pressure head of each quick-clamp would significantly reduce inspection efficiency. Furthermore, configuring two sets of quick-clamps on the inspection bracket—one for clamping individual parts and the other for clamping assemblies—would greatly increase the manufacturing cost of the inspection bracket. Moreover, the limited installation space on the inspection bracket makes it difficult to configure two sets of quick-clamps.

[0004] Therefore, it is necessary to design a clamping device with adjustable height to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable height clamping device for quickly adjusting the clamping action of the clamping structure according to the thickness requirements of the workpiece during the clamping of parts. Compared with the nut adjustment method, it is more convenient and has higher switching efficiency.

[0006] To achieve the above objectives, this utility model employs the following technical solution: This utility model provides an adjustable height clamping device, including a mounting bracket and an adjusting component mounted on the mounting bracket. The adjusting component includes a support body with a through hole in the vertical direction. A pressure rod is slidably mounted in the through hole, and a pressure block is provided at the bottom of the pressure rod. A sliding groove is provided on the support body, and the groove body is connected to the through hole. The two ends of the sliding groove are set as horizontal placement sections with different heights. An adjusting rod is also mounted on the pressure rod, and the rod body can slide in the sliding groove and be positioned within the two placement sections.

[0007] Specifically, the bottom of the pressure block is provided with an elastic layer, the top surface of the placement section of the sliding groove is provided with a recess, and the adjusting rod can be locked in the recess.

[0008] Specifically, the middle part of the sliding groove, located in the non-placement section, is set in an inverted "U" shape, and the groove opening of the placement section of the sliding groove is inclined upward in the direction away from the middle position.

[0009] Specifically, multiple sets of sliding grooves are provided in the vertical direction of the support body, and the multiple sets of sliding grooves are connected to each other through connecting grooves, and the adjusting rod can move in each sliding groove through the connecting grooves.

[0010] Specifically, each set of sliding grooves has a position mark for indicating the height adjustment.

[0011] Specifically, the mounting bracket includes a pad and a connecting component, the connecting component being used to connect the pad and the adjusting component, and the connecting component and the adjusting component being movably connected.

[0012] Specifically, the connecting assembly includes a hinge seat fixedly mounted on the pad block. A connecting block and an adjusting block are respectively hinged to both sides of the hinge seat. The connecting block and the adjusting block are hinged together by a connecting plate. A driving handle is mounted on the connecting plate. The connecting block is used to connect and install the adjusting component. The driving handle is used to change the pressing and releasing state of the adjusting component by changing the position of the connecting plate.

[0013] Specifically, the connecting block and the adjusting component are connected by an adjusting screw. An adjusting nut is mounted on the adjusting screw to lock the connecting block and the adjusting component. A protective component is provided at the contact position between the adjusting nut and the connecting block and the adjusting component.

[0014] Specifically, the hinge seat is provided with a spring acting on the adjusting block and a limiting member, the spring and the limiting member being used to constrain the position range of the adjusting member.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This invention features a sliding groove on the adjusting component and a sliding rod on the pressure rod that can slide within the groove. This allows the height of the pressure block at the bottom of the pressure rod to be adjusted by sliding the adjusting rod. The sliding groove's placement section positions the adjusting rod, ensuring a stable pressing position. By designing at least two placement sections, the pressure block can provide at least two quickly switchable pressing positions, which can be achieved directly by adjusting the position of the adjusting rod. This eliminates the need for threaded adjustment and multiple pressing mechanisms, facilitating switching and improving work efficiency. Attached Figure Description

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] This utility model provides an adjustable-height clamping device for quickly adjusting the clamping action of the clamping structure according to the thickness requirements of the workpiece during component clamping. Compared with the nut adjustment method, it is more convenient and has higher switching efficiency. To realize the structural function of the device, it is set here to include a mounting bracket and an adjusting component 3 set on the mounting bracket, which can be referred to as... Figure 1 as well as Figure 2As shown, the adjusting component 3 includes a support body 301, on which a through hole is provided in the vertical direction. A pressure rod 4 is slidably installed in the through hole, and a pressure block 7 is provided at the bottom of the pressure rod 4. The manufactured parts are pressed by the pressure block 7. In order to facilitate quick adjustment of the pressing position of the pressure block 7 for easy manual adjustment, a sliding groove 302 is provided on the support body 301. The groove of the sliding groove 302 is connected to the through hole, and the two ends of the sliding groove 302 are set as horizontal placement sections with different height positions. At the same time, an adjusting rod 5 is also installed on the pressure rod 4. Finally, the adjusting rod 5 is configured to slide within the sliding groove 302 and be positioned within the two placement sections. With this configuration, the height of the pressure rod 4 can be quickly changed by manually adjusting the position of the adjusting rod 5, thereby altering the pressing position of the bottom pressure block 7. For scenarios requiring rapid positioning of sheet metal, this provides two pressing positions for selection. The actual pressing position can be matched to the required pressing position of the workpiece. This design eliminates the need for repeated tightening of bolts, significantly improving the efficiency and speed of manual assembly. To prevent rigid structural errors from hindering accurate pressing action, an elastic layer is provided at the bottom of the pressure block 7 to compensate for rigidity or structural errors. Alternatively, a recess is provided on the top surface of the placement section of the sliding groove 302, allowing the adjusting rod 5 to be engaged within the recess to prevent slippage and loosening of the pressing position.

[0022] This utility model provides an adjustable height clamping device, specifically a sliding groove 302 structure. Specifically, the middle part of the sliding groove 302, located in the non-placement section, is set as an inverted "U" shape. The concave position of this "U" shape can also serve as the apex for positioning the adjusting rod 5. That is, by providing additional positioning points, more options for the pressing height position can be provided. In order to ensure that the adjusting rod 5 can be stably positioned in the placement sections on both sides and to prevent the pressing position from loosening, the groove opening of the placement section of the sliding groove 302 can be configured to be inclined upward in the direction away from the middle position. The upward inclination angle is used to achieve the locking of the adjusting rod 5.

[0023] This utility model provides an adjustable-height clamping device. To offer more options for clamping height, multiple sets of sliding grooves 302 can be provided in the vertical direction of the support body 301, such as... Figure 2As shown, multiple sets of sliding grooves 302 are interconnected via connecting grooves. The adjusting rod 5 can move within each sliding groove 302 through the connecting grooves. With this configuration, the adjusting rod 5 can be quickly switched to different placement section positions to quickly adjust to different heights. The positioning point can be quickly switched according to the requirements of different composite panels to be pressed. To avoid confusion among workers regarding the matching degree of pressing heights of different placement sections, a position mark 6 for indicating the adjustment height can be provided at the placement section position of each set of sliding grooves 302, indicating which composite panel the current pressing height is suitable for.

[0024] This utility model provides an adjustable height clamping device, specifically a mounting bracket structure. The mounting bracket includes a pad 1 and a connecting component 2. The connecting component 2 connects the pad 1 and the adjusting component 3. The connecting component 2 and the adjusting component 3 are movably connected. This movable connection allows for convenient overall adjustment of the position of the adjusting component 3, including rotation and height adjustment, etc. The specific method is not limited here.

[0025] This utility model provides an adjustable height clamping device. To facilitate lifting the adjusting member 3, in addition to moving the adjusting rod 5, the entire adjusting member 3 can be lifted to release the pressure on the plate. This avoids the inconvenience of removing the plate even after the adjusting rod 5 has reached its highest position. To achieve the complete lifting of the adjusting member 3, a connecting assembly 2 can be provided, including a hinge seat 201 fixedly mounted on the pad 1. Figure 1 As shown, a connecting block 202 and an adjusting block 203 are respectively hinged on both sides of the hinge base 201. The connecting block 202 and the adjusting block 203 are hinged together by a connecting plate 204. A drive handle 205 is installed on the connecting plate 204. The connecting block 202 is used to connect and install the adjusting component 3. With this assembly method, the position of the connecting plate 204 can be changed by manually changing the position of the drive handle 205, thereby changing the pressing and releasing state of the adjusting component 3. In order to improve the positional stability, a spring and a limiting component (not shown in the figure) acting on the adjusting block 203 can be provided on the hinge base 201. The spring and the limiting component are used to constrain the position range of the adjusting component 3 and prevent the adjusting component 3 from moving unstablely under the pressing state.

[0026] This utility model provides an adjustable height clamping device. To facilitate the assembly and adjustment between the adjusting member 3 and the connecting block 202, the connecting block 202 and the adjusting member 3 can be connected by an adjusting screw 208. Figure 1 and Figure 3As shown, an adjusting nut 207 is mounted on the adjusting screw 208 to lock the connecting block 202 and the adjusting component 3. A protective component 206 is provided at the contact position between the adjusting nut 207 and the connecting block 202 and the adjusting component 3. By using the adjusting screw 208 for connection, a height adjusting shim can be easily inserted between the adjusting component 3 and the connecting block 202 to facilitate adjustment of the working height of the adjusting component 3.
