Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to an adjustable jig for a hardware lock assembly workbench. Background Art

[0002] In the process of assembling hardware locks, jigs are needed to clamp and fix the hardware locks. The existing patent is an adjustable jig for precisely positioning hardware products, and the patent publication number is CN219005831U. It includes a workbench, positioning crossbeams symmetrically arranged on the upper side of the workbench, and a clamping crossbeam arranged on the opposite side of the positioning crossbeam. A through extension groove is axially opened at the opposite end of the positioning crossbeam. There are two groups of clamping crossbeams symmetrically arranged in the front and back in the extension groove. At the opposite end of the positioning crossbeam, end pieces are symmetrically connected up and down. Between the end pieces, a first gear and a second gear are arranged. The first gear is installed at the upper end of the second gear through a bearing structure. This adjustable jig adopts a positioning crossbeam equipped with a clamping crossbeam, and the two are used in combination, which can adjust the overall length of the jig in the face of different clamping operations of hardware fittings and change the size of the clamping force-bearing surface with the hardware fittings.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects: In the actual process of clamping and fixing hardware locks with this jig, due to the high precision of some parts in the hardware locks, when using the above jig for clamping, personnel need to rely on experience to control the clamping force. When the clamping force is too large, it is easy to damage the surface or internal structure of the parts of the hardware lock, thus affecting the service life of the hardware lock after assembly. That is, the technical solution proposed by the above patent technology has the defect that personnel cannot precisely control the clamping force of the parts of the hardware lock.
