Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a locking fixture for processing a pump head of a cleaning machine. Background Art

[0002] After the pump head of the cleaner is cast, each hole needs to be fine-machined one by one on a drilling platform. Since the pump head is provided with multiple groups of holes with different directions, a special flat-mouth drill platform is required when drilling. After the corresponding holes are drilled in the pump head, the direction of the pump head needs to be rotated again and adjusted. Each time the direction of the pump head is adjusted, it needs to be re-clamped. This clamping method is too cumbersome, and frequent disassembly and assembly may easily lead to inaccurate positioning after clamping the pump head. Summary of the Invention

[0003] In order to overcome the shortcomings of the background technology, the technical solution adopted by the utility model is: a locking clamp for processing the pump head of a cleaning machine, comprising a base plate, a first mounting seat, a second mounting seat and a pneumatic clamp, and the upper and lower sides of the base plate are respectively fixedly connected with one or more first mounting seats and a second mounting seat, and pneumatic clamps for clamping the pump head are provided on both sides of the first mounting seat / second mounting seat, and the pneumatic clamps are respectively combined with the first mounting seat and the second mounting seat to form a first workstation for processing the pump head connecting hole, and a second workstation for processing the pump head adjustment hole, the pneumatic clamp comprises a cylinder, a rotating seat, an adapter plate and a pressure rod, and the cylinder is fixedly connected with a rotating seat on one side of the output end, and the two ends of the adapter plate are respectively rotatably connected with the rotating seat and the pressure rod, and the pressure rod uses the adapter plate as a fulcrum, one end of the pressure rod is rotatably connected to the output end of the cylinder, and the other end extends above the first mounting seat / second mounting seat.

[0004] By adopting the above technical solution, the drill bits are arranged on both sides of the base plate, and the directions of the pump heads fixed at the first and second stations are different, so that the holes in the four directions of the pump head can be processed, and the conditions for mass production are met, thereby improving production efficiency.

[0005] The present invention is further configured such that the first mounting seat and the second mounting seat have the same structural rotation, the first mounting seat / the second mounting seat are provided with a positioning hole for fixing the pump head, and one end of the pressure rod is provided directly above the positioning hole.

[0006] Furthermore, the first mounting seat / the second mounting seat is provided with an accommodating groove for accommodating the pump head side tube.

[0007] By adopting the above technical solution, the first mounting seat is rotated 90 degrees relative to the second mounting seat and mounted on the bottom plate, so that the parts constituting the first station and the second station are of the same type, which is convenient for installation.

[0008] The utility model is further configured such that the rotating seat and the pressure rod are respectively provided with a first steering hole and a second steering hole, the adapter plate is provided on both sides of the rotating seat and the pressure rod, and the two ends of the adapter plate are rotatably connected to the first steering hole and the second steering hole through a rotating shaft.

[0009] Furthermore, a threaded hole is provided on one side of the cylinder at the output end, and the rotating seat is threadedly connected to the cylinder through the threaded hole.

[0010] Furthermore, one end of the pressure rod is provided with a slot and a third steering hole provided on the slot, and the output end of the cylinder is provided with a mounting portion adapted to the slot, and the mounting portion is rotatably connected to the third steering hole via a rotating shaft.

[0011] By adopting the above technical solution, when the output end of the cylinder contracts, the output end of the cylinder controls the pressure rod to rotate in the direction away from the pressure rod with the first steering hole as the axis, and drives the adapter plate to rotate in the direction of the cylinder with the first steering hole as the axis through the pressure rod, so that the pressure rod moves completely to the top of the cylinder without interfering with the Z-axis direction of the mounting base, so as to facilitate the disassembly or installation of the cleaning machine pump head.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The drill bits are located on both sides of the base plate. The orientations of the pump heads fixed at the first and second stations are different, so the pump heads only need to be re-clamped once to complete the processing of holes in four directions, meeting the conditions for mass production.

[0014] 2. When the output end of the cylinder contracts, the pressure rod and the adapter plate rotate synchronously and move to the top of the cylinder, so that the pressure rod does not interfere with the Z-axis direction of the first mounting seat / second mounting seat, so as to facilitate the disassembly or installation of the cleaning machine pump head.

[0015] The embodiments of the present invention will be further described below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
