Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a positioning workbench for precision sheet metal machining. Background Art

[0002] Sheet metal refers to metal products processed from thin sheet metal into various shapes. These shapes may include flat plates, bends, stamping, and forming, etc. Sheet metal products are widely used in various industries and fields. Common sheet metal materials include cold-rolled steel sheets, galvanized sheets, aluminum sheets, stainless steel sheets, etc. Sheet metal products have the characteristics of light weight, high strength, corrosion resistance, flat surface, and low manufacturing cost, so they are widely used in the manufacture of various products and components. After some sheet metal parts are processed, they may also have other processing procedures. At this time, a positioning workbench for sheet metal processing is needed to fix the sheet metal parts to facilitate secondary processing.

[0003] Currently, most workbenches are for fixing flat sheet metal parts. When it is necessary to fix sheet metal parts with arc surfaces, the force on the arc surface may be uneven, causing deformation on its surface, resulting in depressions on the surface of the sheet metal parts and affecting the quality. Moreover, generally, the operator processes around the sheet metal parts, which is likely to consume the physical strength of the staff. Therefore, those skilled in the art provide a positioning workbench for precision sheet metal machining to solve the problems raised in the above background art. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a positioning workbench for precision sheet metal machining is proposed. During the operation of the device, with the help of multiple fixed columns and oil cylinders, it is helpful to meet the clamping requirements of various sheet metal parts, and at the same time avoid excessive pressure on a certain part of the curved sheet metal parts, resulting in deformation. In addition, through the design of the stop block and the slider, the moving path of the fixture can be effectively shielded, preventing debris generated during the processing from entering the internal part of the bottom plate support, thus ensuring the normal operation of the device. The configuration of the bottom plate and the gear ring helps to drive the entire clamping mechanism to rotate, facilitating the operator to process the sheet metal parts, reducing the physical strength consumption caused by processing around the sheet metal parts, and improving work efficiency. At the same time, the bottom plate and the gear ring wrap the second gear inside, effectively preventing it from being blocked by other foreign objects.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A positioning workbench for precision sheet metal machining, including a bottom plate, a support table, a support plate, and a gear ring. A first gear is rotatably arranged inside the upper end of the bottom plate, two racks are slidably arranged inside the upper end of the bottom plate, the two racks are meshed with the first gear, and fixtures are fixedly arranged at the ends of the two racks away from the first gear.

[0007] Through the above technical solution, when the device is in use, the second motor drives the first gear to rotate. The first gear drives the two racks to move in opposite directions. The two racks drive the two jigs to move in opposite directions until the article is fixed. When clamping a curved article, the fixing column that first contacts the article will fit the surface of the article. The remaining fixing columns that do not contact the article will continue to move forward under the push of the hydraulic oil in the oil cylinder until the article is fixed. In addition, when the jig moves forward, the stop block will squeeze the slider to one side until the jig passes through. After the jig passes through, the slider will return to its original position, which is beneficial to preventing the debris generated during processing from entering the inside and affecting its normal operation.

[0008] Further, the bottom plate is rotatably arranged on the upper end of the support platform, and the two jigs are slidably arranged on the upper end of the support plate.

[0009] Through the above technical solution, the bottom plate is beneficial to installing the support platform, the first gear and the rack. Through the two jigs, it is beneficial to fixing the sheet metal part.

[0010] Further, at the center of the lower end of the support platform, a second bracket is fixedly arranged. Inside the upper end of the second bracket, a second motor is fixedly arranged.

[0011] Through the above technical solution, the second bracket is beneficial to installing the second motor. Through the second motor, it is beneficial to driving the first gear to rotate.

[0012] Further, at one side of the lower end of the support platform, a first bracket is fixedly arranged. Inside the first bracket, a first motor is fixedly arranged. At the output end of the first motor, a second gear is fixedly arranged.

[0013] Through the above technical solution, the first bracket is beneficial to installing the first motor. Through the first motor, it is beneficial to driving the second gear to rotate. Through the second gear, it is beneficial to driving the gear ring to rotate.

[0014] Further, a gear ring is fixedly arranged around the lower end of the bottom plate, and the second gear meshes with the gear ring.

[0015] Through the above technical solution, the toothed ring is beneficial to drive the bottom plate to rotate and also beneficial to enclose the second gear therein to protect its normal operation.

[0016] Furthermore, soft heads are fixedly arranged on the relative sides of the plurality of fixing columns, and both sides of the plurality of baffles are closely attached.

[0017] Through the above technical solution, the soft heads are beneficial to prevent scratches on the surface of relatively smooth sheet metal parts during clamping, and the baffles are beneficial to prevent debris from entering the inside of the gear.

[0018] Furthermore, the toothed ring fits with the support table.

[0019] Through the above technical solution, it is beneficial to prevent foreign objects from jamming the second gear.
