Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal precision processing, in particular to a multi-directional sheet metal precision processing positioning device. Background Technique

[0002] Sheet metal precision processing is a manufacturing process used to process metal sheets into required shapes and sizes. This technology is widely applied in various industries, including automobile manufacturing, electronic devices, aerospace, etc. The process of sheet metal precision processing includes steps such as cutting, bending, stamping, welding, etc. to meet the requirements of customers and design requirements. During the precision processing of sheet metal, a positioning device is usually required to clamp and fix it to prevent its position from shifting during the processing.

[0003] Patent No. CN219542953U discloses a sheet metal processing positioning tooling, including a workbench. Fixed frames are installed on both sides of the bottom end of the workbench. Clamping mechanisms are arranged at the mutually remote ends of the two fixed frames. Placing frames are installed on the left and right sides of the top end of the workbench, and strip-shaped grooves are penetratingly opened on the front and rear sides of the top end of the workbench. The clamping mechanism includes a first movable block, a second movable block, a movable plate, a first slider, a second slider and a guide rail. The utility model is provided with a clamping mechanism. The output end of a servo motor drives a threaded rod to rotate, so that the first movable block and the second movable block, as well as the first slider and the second slider, approach each other, and then the movable plate moves horizontally, so that the placing frames on both sides approach each other to horizontally clamp the sheet metal to be processed. Secondly, the cooperation of a cylinder and a pressing plate is used. The output end of the cylinder drives the pressing plate to move downward for longitudinal clamping.

[0004] However, the above-mentioned sheet metal processing positioning tooling still has the following deficiencies:

[0005] Although the above device can horizontally clamp the sheet metal to be processed through the clamping mechanism, and the output end of the cylinder drives the pressing plate to move downward to longitudinally clamp the sheet metal to be processed, the sheet metal often needs to be processed on more than one side. Therefore, the sheet metal in the above device needs to be manually flipped and adjusted, and then re-limited through the clamping mechanism and the cylinder, which is rather inconvenient and reduces the processing efficiency. In view of this, we propose a multi-directional sheet metal precision processing positioning device. Content of the Utility Model

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a multi-directional sheet metal precision processing positioning device to solve the technical problems that the sheet metal in the above device needs to be manually flipped and adjusted, and then re-limited through the clamping mechanism and the cylinder, which is rather inconvenient and reduces the processing efficiency.

[0007] To achieve the object of the present utility model, the technical solution adopted by the present utility model is: to design a multi-directional precision positioning device for sheet metal processing, including a base, wherein an adjusting mechanism is provided in the middle of the base, and a group of clamping mechanisms are symmetrically provided on the surface of the adjusting mechanism, and a sheet metal part is clamped inside the group of clamping mechanisms;

[0008] The clamping mechanism includes a positioning frame fixed on the surface of the adjusting mechanism. A driving motor is provided inside the positioning frame. The movable end of the driving motor is connected to a T-shaped rod. The end of the T-shaped rod away from the driving motor is connected to a limiting frame. A group of hydraulic cylinders I are symmetrically provided inside the limiting frame. The movable ends of the group of hydraulic cylinders I are symmetrically connected to a group of clamping frames. A bracket is attached to the outside of the clamping frame, and a hydraulic cylinder II is connected to the bottom of the bracket.

[0009] Preferably, the T-shaped rod is fixedly connected to the limiting frame, and the clamping frame forms a telescopic structure with the limiting frame through the hydraulic cylinder I.

[0010] Preferably, the clamping frame is clamped inside the bracket, and the bracket forms a lifting structure with the limiting frame through the hydraulic cylinder II.

[0011] Preferably, the adjusting mechanism includes a positive and negative screw rod arranged inside the base. The end of the positive and negative screw rod is connected to a small motor. A fixed frame is attached to the outside of the small motor. A group of support plates are symmetrically sleeved on the surface of the positive and negative screw rod.

[0012] Preferably, the bottom of the support plate is clamped inside the base, and the support plate is in threaded connection with the positive and negative screw rod.

[0013] Preferably, the T-shaped rod is movably clamped inside the support plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, the sheet metal part is placed on the surface of the bracket. A group of hydraulic cylinders I effectively drive a group of clamping frames to approach the sheet metal part, so as to perform horizontal centering limit on the sheet metal part. Then, the hydraulic cylinder II effectively drives the bracket to move upward, so that the top of the sheet metal part fits with the top inside the clamping frame, realizing vertical limit on the sheet metal part, improving the limit stability. A group of driving motors effectively drive a group of T-shaped rods and the limiting frame to rotate synchronously, so as to realize the rotation of the sheet metal part clamped inside the limiting frame, facilitating the flipping adjustment of different surfaces of the sheet metal part and improving the processing efficiency.

[0016] 2. In the present utility model, the small motor effectively drives the positive and negative screw rod to rotate, thereby driving a group of support plates sleeved on the surface of the positive and negative screw rod to move away from or close to each other, and further adjusting the distance between the group of support plates, facilitating the limitation of sheet metal parts with different lengths inside a group of clamping mechanisms and improving the applicability.

[0024] A multi-directional precision machining positioning device for sheet metal, see Figures 1 to 3 , including a base 1, an adjusting mechanism 2 is provided in the middle of the base 1, a group of clamping mechanisms 3 are symmetrically provided on the surface of the adjusting mechanism 2, and a sheet metal part 4 is clamped inside a group of clamping mechanisms 3;

[0025] The clamping mechanism 3 includes a positioning frame 301 which is fixed on the surface of the adjusting mechanism 2. A driving motor 302 is arranged inside the positioning frame 301. The movable end of the driving motor 302 is connected with a T-shaped rod 303. One end of the T-shaped rod 303 away from the driving motor 302 is connected with a limiting frame 304. A group of hydraulic cylinders 305 are symmetrically arranged inside the limiting frame 304. The movable ends of the group of hydraulic cylinders 305 are symmetrically connected with a group of clamping frames 306. Among them, the T-shaped rod 303 is fixedly connected with the limiting frame 304. The clamping frame 306 and the limiting frame 304 form a telescopic structure through the hydraulic cylinder 305. The outer side of the clamping frame 306 is attached to a bracket 307. A hydraulic cylinder 308 is connected to the bottom of the bracket 307. Further, the clamping frame 306 is clamped inside the bracket 307. The bracket 307 and the limiting frame 304 form a lifting structure through the hydraulic cylinder 308. In the present utility model, the sheet metal part 4 is placed on the surface of the bracket 307. A group of hydraulic cylinders 305 effectively drive a group of clamping frames 306 to approach the sheet metal part 4, so as to perform horizontal centering limitation on the sheet metal part 4. Then, the hydraulic cylinder 308 effectively drives the bracket 307 to move upward, so that the top of the sheet metal part 4 fits with the top inside the clamping frame 306, realizing vertical limitation on the sheet metal part 4, improving the limitation stability. A group of driving motors 302 effectively drive a group of T-shaped rods 303 and the limiting frame 304 to rotate synchronously, so as to realize the rotation of the sheet metal part 4 clamped inside the limiting frame 304, facilitating the flipping adjustment of different surfaces of the sheet metal part 4 and improving the processing efficiency.

[0026] It should be noted that the adjusting mechanism 2 includes a positive and negative lead screw 201 which is arranged inside the base 1. The end of the positive and negative lead screw 201 is connected with a small motor 202. A fixed frame 203 is attached to the outside of the small motor 202. A group of support plates 204 are symmetrically sleeved on the surface of the positive and negative lead screw 201. Among them, the bottom of the support plate 204 is clamped inside the base 1. The support plate 204 is in threaded connection with the positive and negative lead screw 201. Further, the T-shaped rod 303 is movably clamped inside the support plate 204. In the present utility model, the small motor 202 effectively drives the positive and negative lead screw 201 to rotate, thereby driving a group of support plates 204 sleeved on the surface of the positive and negative lead screw 201 to move away from or close to each other, and further adjusting the distance between the group of support plates 204, facilitating the limitation of sheet metal parts 4 with different lengths inside a group of clamping mechanisms 3 and improving the applicability.

[0027] Working principle: A small motor 202 drives a positive and negative lead screw 201 to rotate, thereby driving a group of support plates 204 sleeved on the surface of the positive and negative lead screw 201 to move away from or close to each other, and further adjusting the distance between the group of support plates 204. Sheet metal parts 4 of different lengths can be limited inside a group of clamping mechanisms 3. After the sheet metal parts 4 are placed on the surface of the bracket 307, a group of hydraulic cylinders 305 drive a group of clamping frames 306 to approach the sheet metal parts 4, so as to perform horizontal centering limit on the sheet metal parts 4. Then, the hydraulic cylinder 308 drives the bracket 307 to move upward, so that the top of the sheet metal parts 4 fits with the inner top of the clamping frame 306, realizing the vertical limit on the sheet metal parts 4. Subsequently, a group of drive motors 302 drive a group of T-shaped rods 303 and the limit frame 304 to rotate synchronously, and the rotation of the sheet metal parts 4 clamped inside the limit frame 304 can be realized, which is convenient for flipping and adjusting different surfaces of the sheet metal parts 4 and improving the processing efficiency.
