Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a workbench processing unit, in particular to a workbench with angle adjustment.

State of the art

High precision and angular adjustable workbenches are currently known. One is described in Chinese Patent Application WO02009033421 CN.

In the field of processing equipment, desktop equipment is often used to provide a platform for processing processes. Heavy-duty workpieces are often required in some areas of processing, then heavy-weight processing equipment is used. Then the workbench often has to withstand enormous load.

And in the machining process, adjustable desktop angles are required to meet the requirements for interoperability with other machining equipment, depending on the processing process. However, some of the existing angle adjustment methods are difficult to meet support requirements during overload during the adjustment process. In addition, drive units are often complex, covering relatively large space, which adds additional requirements to the installation of the production line and the utilization of the factories, the creation of the production line and increased labor costs.

The essence of the invention

It is an object of the present invention to provide a workbench with angular adjustment for machining that can overcome the above disadvantages.

Angle adjustable workbench for mechanical processing comprising stand, shaft, slides, having stand, workpiece members hinged to the top of said stand via pivot shaft, and angle adjusting support slider members which may slide in the gutter mounted on the bottom . Between said elements of said angle adjusting support slider there is located a main body in the middle and two slopes arranged according to vertical symmetry, said two slopes respectively being fitted with a symmetrically inclined plane tube for internal sliding of the left support slider and the right support slider respectively. In both of these inclines, the top and bottom of the inclined plane tube are provided with mounting blocks. The guide bars parallel to said inclined tube are fixedly mounted in said mounting blocks. Said mounting blocks pass through said left support slider and right support slider, and said left support slider and right support slider are pivotally connected to the support legs at the left and right ends of said desktop members. Said rack is provided with a left propeller support portion and a right propeller support portion between said two recesses extending to the lower slider members of said angle adjustment support, the front drive screw and the rear drive screw being disposed between said left screw support portion and the right propeller portion. The said front drive screw and the rear drive screw operate in conjunction with the helical thread of the helical thread interaction portion between the left screw support portion and the right screw bearing portion extending downstream of said main body and rear portion of said angle adjusting slider elements in the middle. parts of the helical thread interaction group include the parts of the left screw thread interaction and the parts of the right screw thread interaction. The propeller wheels between said left-hand screw thread engagement parts and the right-hand screw thread engagement parts are provided at each of said front-drive screws and rear-drive screws. One of the distances (L2) between said propeller drive wheels or the left screw auger interaction parts or the right auger thread interaction parts is substantially equal to the distance between one of the left screw auger interaction parts and the right auger thread interaction parts to said front drive auger and rear drive propeller spacing (L1). Each drive wheel of the front propeller and the rear propeller of the propeller are connected by the gear belt energy. The said gear belt is driven by a worm gear mounted in said riser and also in the middle of two propeller drive wheels. The left elastic contact switch is mounted on the left side of said left screw propeller and the right elastic contact switch is mounted on the right side of the right screw bearing member, and said left elastic contact switch and the right elastic contact switch are parallel. The signal lights are electrically connected to said left elastic contact switch and the right elastic contact switch mounted on said desktop components. When said left elastic contact switch or right elastic contact switch contacts said two slopes, said signal lights illuminate to indicate that the inclination angle of said desktop elements has reached a limiting position.

The present invention is structurally symmetrical with two sets of inclined lifting blocks that can always support the workbench with two right and left foot adjusting the workbench. The mechanical stability of the workbench is increased during angle adjustment so that it can still maintain stable worktop support at any time. Through the installation of two screws in the front and rear positions, by synchronously controlling and moving the control units, can match the large support energy distribution in the longitudinal direction of the desktop, achieving propulsion and support force distribution at the edges and corners of the desktop to improve mechanical stability. Due to the mounting of the drive wheel in the center of each propeller, as well as the propeller drive protrusion separated by the support frame, the bilateral symmetry can match the result of the distribution of drive force on the left and right and balanced energy output on both sides. the middle space, maintaining the energy coupling space with the source of the propulsion, under the condition of non-interference with the movement of the slider. This also permits the use of a middle space between right-hand thread movement of the left-hand threads, boundary position and left-hand movements of right hand threads, so that the overall drive layout is balanced and the mechanical design is compact. This arrangement may also be implemented by supporting two screws through an arrangement in one part of the rod between the two inclines.

Synchronous belt assembly combines two front and rear propellers and drives the drive wheel in the center of the arch synchronously, meeting the requirements of front and rear propeller synchronous operation, while simultaneously balancing power, mid-point power points, and proper synchronous belt the wrapping angle formed by the full utilization of the center cavity of the angle adjusting slide.

The entire device is stable and reliable, and the mechanical design is compact with a reasonable layout. It can hold the desktop firmly and make the angle adjustment of the desktop stable.
