Technical Field

When processing automobile parts, automobile fixtures are one of the frequently used processing tools;

[0003] Chinese Patent Grant Application No.: CN201920599141.8 provides an easy-to-operate automobile fixture. This solution can facilitate the flipping of welded parts during the welding process, reduce the trouble of re-clamping. The plane where the lower end of the fixed frame is located is higher than the plane where the top end of the first motor box is located, so that the fixed frame is not easy to touch the first motor box when rotating under the action of the second motor box. Two pairs of universal wheels are connected to the lower end of the counterweight seat, and the universal wheels are equipped with brake pads, which is convenient for moving this device. Rubber pads are connected to the opposite side walls of a pair of movable clamping plates, and anti-slip protrusions are connected to the rubber pads, so that the welded parts are not easy to be scratched by the movable clamping plates and generate scratches, affecting the appearance.

[0004] Existing automobile fixtures have certain drawbacks when in use. First of all, the structure of automobile fixtures is single, and traditional automobile fixtures are inconvenient to adjust. Therefore, most existing automobile fixtures are of adjustable positioning structures. However, when the automobile fixture processes products that generate a certain amount of vibration force during positioning, the external force is transmitted to the automobile fixture, resulting in a decrease in the stability of the structural connection after long-term use, and a decrease in the use stability and service life of the automobile fixture. For this reason, we propose an automatic clamping system for an automobile fixture. Content of the Utility Model

By setting clamping blocks and spring members, the acting force received by the fixture can be effectively conducted, buffered and inhibited, so that the automatic clamping system of the automobile fixture is more stable during positioning, will not fall off due to vibration force, and increases the service life of the structure of the automatic clamping system of the automobile fixture, which is used to solve the problem of loosening of the structure caused by the long-term action of vibration force on the fixture; by setting, the buffer member cooperates with the spring member to make the device have multiple buffer components, and the inhibition structure of the buffer member effectively prevents the clamping block from rebounding; setting a moving frame to drive the positioning mechanism to adjust the horizontal position, so that the clamping structure can perform clamping processing work at different positions; setting a rotating member to enable the second screw to rotate conveniently and have a threaded effect with the guide block, which is convenient for the guide block to move and drive the positioning mechanism to adjust and position.

Detailed implementation manners

[0035] The following further elaborates on the present utility model in detail with reference to the accompanying drawings.

[0036] Among them, the same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0037] Referring to Figure 1-5 as shown, a kind of automatic clamping system for an automotive fixture in a preferred embodiment of the present utility model includes a body mechanism 1, an adjusting mechanism 2 is installed at the outer end of the body mechanism 1, and a positioning mechanism 3 is installed at the lower end of the adjusting mechanism 2;

[0038] The positioning mechanism 3 includes a fixture body 301, which is symmetrically distributed. An infrared sensor 302 is movably connected to the inner side of the fixture body 301. Clamping blocks 303 are slidably connected to the outer ends of the fixture body 301. A buffer block 304 is installed at the rear end of the clamping block 303. Symmetrically distributed buffer rods 305 are hinged to the outer end of the buffer block 304. The other end of the buffer rod 305 far from the buffer block 304 is hinged to a slider 306. A spring member 307 is installed at the outer end of the slider 306.

[0039] Refer to Figure 2-3 As shown, a buffer member 308 is slidably connected to the inner side of the spring member 307. The buffer member 308 is located at the bottom end of the buffer block 304.

[0040] Refer to Figure 3 As shown, a buffer groove 309 is formed at the outer end of the spring member 307. The buffer groove 309 is located at the inner end of the fixture body 301.

[0041] By installing the clamping block 303 and the spring member 307, the clamping block 303 can position at both ends of the product. When the fixture clamps the product and vibration force is generated during processing, the acting force drives the buffer block 304 and the buffer rod 305 to generate displacement. At this time, the vibration force conducted by the buffer rod 305 is buffered by the spring member 307. The buffer member 308 cooperates with the spring member 307 to enable the device to have multiple buffer components, and the suppression structure of the buffer member 308 effectively prevents the clamping block 303 from rebounding, enabling the acting force received by the fixture to be effectively conducted, buffered and suppressed, making the positioning of the automatic clamping system of the automotive fixture more stable, preventing it from falling off due to vibration force, and increasing the service life of the structure of the automatic clamping system of the automotive fixture.

[0042] Refer to Figure 1 As shown, the body mechanism 1 includes a mounting frame 101. A conduction rod 102 is installed at the inner end of the mounting frame 101. The conduction rods 102 are symmetrically distributed. A transmission end of the conduction rod 102 is fixedly connected to a guide frame 103.

[0043] Refer to Figure 1 and 5 As shown, a chute 104 is formed at the outer end of the guide frame 103. A symmetrically distributed support 105 is fixedly connected to the front end of the guide frame 103. A driving member 201 is installed at the left end of the support 105.

[0044] By installing the guide frame 103, the guide frame 103 can slide under the telescopic acting force of the conduction rod 102, thereby driving the positioning mechanism 3 to be able to adjust its position, enabling the positioning mechanism 3 to position at different positions.

[0045] Refer to Figure 1 and 5As shown, a first screw rod 202 is fixedly connected to the transmission end of the driving member 201. A moving frame 203 is sleeved on the outer end of the first screw rod 202. The moving frame 203 has an L-shaped structure. A cylinder 204 is installed at the top end of the moving frame 203. A connecting frame 205 is fixedly connected to the transmission end of the cylinder 204. A positioning frame 206 is installed at the bottom end of the connecting frame 205.

[0046] Referring to Figure 4 and 5 As shown, a rotating member 207 is installed at the upper end of the positioning frame 206. A second gear 208 is meshed and connected to the outer end of the rotating member 207. A second screw rod 209 is installed at the inner end of the second gear 208. Bearing frames 210 are installed at both ends of the second screw rod 209.

[0047] Referring to Figure 4 As shown, symmetrically distributed guide blocks 211 are sleeved on the outer end of the second screw rod 209. A notch 212 is opened at the outer end of the guide block 211.

[0048] By installing the moving frame 203 to perform a threading action along with the rotating first screw rod 202, the positioning mechanism 3 can be driven to adjust its horizontal position. Cooperating with the cylinder 204, the positioning mechanism 3 below can be lifted and lowered, enabling the clamping structure to perform clamping processing work at different positions as needed. The rotating member 207 consists of a motor and a first gear and can drive the second gear 208 and the second screw rod 209 to rotate simultaneously, allowing the second screw rod 209 to rotate conveniently and perform a threading action with the guide block 211, facilitating the movement of the guide block 211 to drive the positioning mechanism 3 to adjust and position its position.

[0049] Specific implementation process: Adjust the position according to the clamping requirement. The guide frame 103 can slide under the telescopic force of the transmission rod 102, thereby driving the positioning mechanism 3 to adjust its position. The moving frame 203 performs a threading action along with the rotating first screw rod 202, thereby driving the positioning mechanism 3 to adjust its horizontal position. Cooperating with the cylinder 204, the positioning mechanism 3 below can be lifted and lowered, enabling the clamping structure to perform clamping processing work at different positions as needed.

[0050] At this time, the infrared sensor 302 senses the clamped workpiece, and the rotating member 207 is activated. The rotating member 207 consists of a motor and a first gear and can drive the second gear 208 and the second screw rod 209 to rotate simultaneously, enabling the second screw rod 209 to rotate conveniently and engage with the guide block 211 through threads, facilitating the movement of the guide block 211 to drive the positioning mechanism 3 to adjust and position its position. The clamping blocks 303 can position at both ends of the product. When the fixture clamps the product and generates vibration force during processing, the acting force drives the buffer block 304 and the buffer rod 305 to displace. At this time, the vibration force conducted by the buffer rod 305 is buffered by the spring member 307, and the buffer member 308 cooperates with the spring member 307 to make the device have multiple buffer components. Moreover, the suppression structure of the buffer member 308 effectively prevents the clamping blocks 303 from rebounding, enabling the acting force received by the fixture to be effectively conducted, buffered, and suppressed, making the positioning of the automatic clamping system of the automotive fixture more stable, preventing it from falling off due to vibration force, and increasing the service life of the structure of the automatic clamping system of the automotive fixture.
