Description

Technical Field

[0001] The utility model relates to a high-pressure water cleaning fixture suitable for cleaning a hydraulic valve body, belonging to the technical field of casting valve body cleaning. Background Art

[0002] Cleanliness of the cast valve body is a key characteristic in the manufacture of cast multi-way valves and also one of the most difficult aspects of machining. Cast valve bodies are complex in shape, with numerous blind, deep, oblique, and cross holes. Many types and quantities of holes are present, and machining often results in residual iron filings in the holes and undercuts. Furthermore, the casting surface is susceptible to sand, scale, and rust, all of which must be cleaned.

[0003] Cast multi-way valves are control components for engineering machinery. One of their key components is the cast valve body, a complex structure that cannot be thoroughly cleaned using conventional cleaning methods such as ultrasonic cleaning, low-pressure water jet cleaning, low-pressure spray cleaning, immersion cleaning, and rinsing. Cleanliness is a key factor in hydraulic system failure. Researching cleaning technologies for cast valve bodies to improve their cleanliness, enhance the performance and service life of cast multi-way valves, and improve their market competitiveness is a strong driving force.

[0004] The existing patent discloses a cleaning fixture kit (CN202022075529.3). This technology has the following shortcomings:

[0005] 1. The product cleaning fixture described in the patent is provided with a number of profiling bosses for carrying products. The profiling bosses have a complex structure and are difficult to manufacture.

[0006] 2. The product cleaning fixture mentioned in the patent limits the product by means of a contoured boss in conjunction with a positioning column. The contoured boss supports the product through a tapered top, and the clamping structure is complex. Summary of the Invention

[0007] In view of the deficiencies in the prior art, the utility model provides a high-pressure water cleaning fixture suitable for cleaning hydraulic valve bodies, which solves the high cost and low efficiency problem of matching special cleaning fixtures for cast valve bodies of different specifications.

[0008] The utility model is implemented according to the following technical solutions:

[0009] A high-pressure water cleaning fixture suitable for cleaning a hydraulic valve body, comprising:

[0010] a fixture base plate, the top surface of which is capable of placing at least one cast valve body;

[0011] a plurality of positioning blocks, arranged around the periphery of the at least one cast valve body and fixed to the fixture bottom plate, for limiting the lateral movement of the at least one cast valve body on the fixture bottom plate;

[0012] A plurality of quick pressing components are arranged on the periphery of the at least one casting valve body and then fixed on the fixture bottom plate, and are used to press the at least one casting valve body onto the fixture bottom plate.

[0014] In some embodiments, the side structure of the right-angle positioning block facing the casting valve body is configured as a stepped platform adapted to the angle structure of the bottom of the casting valve body, so that the casting valve body can be seated in the right-angle positioning block.

[0015] In some embodiments, when the fixture base plate is placed on a cast valve body assembly consisting of multiple side-by-side cast valve bodies, the multiple positioning blocks are composed of four right-angle positioning blocks and multiple T-shaped positioning blocks; wherein, the four right-angle positioning blocks are respectively arranged at the four angles of the cast valve body assembly to limit the movement of the cast valve body assembly in the lateral direction; two symmetrically arranged T-shaped positioning blocks are provided in the gap between two adjacent cast valve bodies in the cast valve body assembly to limit the movement of the two cast valve bodies in the lateral direction at the same time.

[0016] In some embodiments, the side structures of the right-angle positioning block and the T-shaped positioning block facing the cast valve body are both configured as stepped platforms adapted to the angle structure at the bottom of the cast valve body, so that the cast valve body can be seated in the right-angle positioning block and the T-shaped positioning block.

[0017] In some embodiments, the fixture bottom plate is provided with a hollow structure in the area below the cast valve body, so as to avoid the bottom surface structure of the cast valve body.

[0018] In some embodiments, the rapid compression component includes:

[0019] a pressure clamp base, the bottom of which is fixed to the clamp bottom plate and the top of which is higher than the cast valve body;

[0020] A quick clamp is fixed on the top of the clamp base and is used to provide vertical downward pressure on the cast valve body.

Its instantaneous impact force is used to continuously act on the surface of the workpiece to be cleaned in a fixed and positioned manner, ultimately achieving the purpose of precision cleaning. At the same time, it can remove some small burrs and burrs produced after machining.
