Description

Technical Field

[0001] The invention relates to the technical field of general equipment manufacturing, in particular to a water pump housing machining fixture. Background Art

[0002] A water pump is a machine used to transport liquids or increase the pressure of liquids. The water pump can transfer the mechanical energy of the prime mover or other external energy to the liquid, thereby increasing the energy of the liquid. It is mainly used to transport liquids. The water pump casing is an important component of the water pump, which can protect the internal components of the water pump. It is generally cast with cast iron material.

[0003] After the water pump shell is cast, it is also necessary to drill holes at the corresponding positions of the shell to facilitate the adaptation of the internal parts of the water pump. Therefore, a clamp is needed to fix the water pump shell to facilitate the processing of the shell. The existing clamps generally clamp the shell from the outside, so the local position of the shell will be blocked, which is not convenient for all-round processing of the shell. Therefore, further improvements can be made. Summary of the invention

[0010] Furthermore, the connecting rod is slidably connected inside the slide groove, and the threaded rod is threadedly connected in the threaded groove.

[0018] Compared with the prior art, the present invention provides a water pump housing processing fixture, which has the following beneficial effects:

[0019] 1. The water pump housing processing fixture rotates inside the threaded groove through the threaded rod, and then drives the support rod to move downward along the inner wall of the slide groove through the connecting rod, so it will drive the positioning component to move downward as a whole. At this time, the rotating wheel will roll along the inclined surface of the truncated table, and then the front rotating plate and the rear rotating plate will be forked apart, so it will drive the side pressure assembly to abut against the inner wall of the housing, and then the housing will be fixed and limited from the inside of the housing, thereby achieving the effect of fixing and limiting the housing from the inside.

[0020] 2. The water pump housing processing fixture, through the turntable contacting and abutting the inner wall of the housing, will drive the slide plate to slide into the limit groove, so it will squeeze the inclined surface of the wedge block, so that the wedge block slides downward along the inner wall of the groove plate, and then the extrusion seat will be driven to move downward through the support rod, so the extrusion seat will be pressed downward on the bottom wall of the housing, further fixing and limiting the housing, thereby facilitating all-round processing of the outer side of the housing.

[0035] See also Figure 5-6The cam 772 is pressed against the top of the depression 742 of the depression 743 and the depression 744 is in the downward direction of the depression 743. The cam 772 is pressed against the depression 743 of the depression 743 when the depression 744 is in the downward direction of the depression 743.

[0036] How it works: See Figure 1-6 First, place the water pump housing on the cylinder 5, at which time the positioning component 7 is located inside the housing, and then start the motor 62 to drive the threaded rod 63 to rotate. The threaded rod 63 rotates in the threaded groove 663, which will cause the connecting rod 662 to drive the support rod 66 to move downward along the inner wall of the slide groove 65, so that the front rotating plate 71 and the rear rotating plate 72 will be driven to move downward synchronously, and then the wheels 73 at the bottom ends of the front rotating plate 71 and the rear rotating plate 72 will roll along the inclined surfaces on both sides of the round table 64, so that the front rotating plate 71 and the rear rotating plate 72 will be forked, and then the side pressure assembly 76 will be driven to abut against the inner wall of the housing, so that the housing will be fixed and limited from the inside of the housing;

[0037] At the same time, when the side pressure assembly 76 is close to the inner wall of the shell, the turntable 765 will abut against the inner wall of the shell, and the slide plate 763 will be squeezed and slide into the limiting groove 762, so it will squeeze the inclined surface of the wedge block 771, so that the wedge block 771 slides downward along the inner wall of the groove plate 77, and then drives the extrusion seat 773 to move downward through the support rod 772, so the extrusion seat 773 will be squeezed downward on the bottom wall of the shell, further fixing and limiting the shell.

[0038] To sum up, the water pump housing processing fixture rotates inside the threaded groove 663 through the threaded rod 63, and then drives the support rod 66 to move downward along the inner wall of the slide groove 65 through the connecting rod 662, so it will drive the positioning component 7 to move downward as a whole. At this time, the rotating wheel 73 will roll along the inclined surface of the table 64, and then the front rotating plate 71 and the rear rotating plate 72 will be forked apart, so it will drive the side pressure assembly 76 to abut against the inner wall of the housing, and then the housing will be fixed and limited from the inside of the housing, thereby achieving the effect of fixing and limiting the housing from the inside.

[0039] By contacting the turntable 765 with the inner wall of the shell, the slide plate 763 will be driven to slide into the limiting groove 762, so it will squeeze the inclined surface of the wedge block 771, so that the wedge block 771 slides downward along the inner wall of the groove plate 77, and then the extrusion seat 773 will be driven to move downward through the support rod 772, so the extrusion seat 773 will be pressed downward on the bottom wall of the shell, further fixing and limiting the shell, thereby facilitating all-round processing of the outer side of the shell.
