Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder painting technology, specifically a tooling for hydraulic cylinder painting. Background Technology

[0002] In hydraulic supports, the cylinders used to support the hydraulic supports need to be painted during the production process. Since the cylinders are large in size and weight, most existing cylinders require a crane to lift the entire cylinder during manual painting, so that the cylinder is suspended in the air before painting. Therefore, a tooling for painting cylinders is needed.

[0003] Chinese Utility Model Patent Publication No. CN214917282U discloses a tooling for painting hydraulic cylinders. During painting, a fixing pin is inserted into a hinge hole, and two limiting seats are inserted into limiting grooves on the adjacent sides of two limiting rods. The fixing pin and the two limiting rods support and fix the hydraulic cylinder, enabling painting while preventing shaking and improving safety. However, this tooling also has drawbacks: paint tends to stick to the base frame during painting, hindering subsequent use and making it difficult to paint multiple hydraulic cylinders simultaneously, resulting in low production efficiency and limiting its widespread adoption. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a tooling for painting hydraulic cylinders, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a tooling for oil cylinder painting, including a base frame, a sealing plate and an oil cylinder assembly. A square tube frame 1 is fixedly installed at the four corners of the base frame. A square tube frame 2 is welded to the end of the square tube frame 1 away from the base frame. A positioning assembly is fixedly installed on the base frame. A through groove is opened on the base frame. A pin is inserted through the oil cylinder assembly.

[0006] The positioning component includes a gasket, with positioning holes one at each of the four corners of the gasket, and through holes and positioning holes two through the gasket. The pin passes through the cylinder assembly and positioning hole one.

[0007] Preferably, a caster is provided at one end of the square tube frame away from the base frame, and the caster is a high-temperature resistant all-iron caster.

[0008] Through the above technical solution, square tube frame one and square tube frame two are welded to form a three-dimensional support frame, which provides rigid vertical support for the base frame. All-iron casters are installed at the end of square tube frame one, allowing the tooling to move flexibly on the workshop floor. Moreover, the all-iron structure is not afraid of high temperatures when entering the spraying line.

[0009] Preferably, the cylinder assembly includes a cylinder body, and an output frame is provided at one end of the cylinder body near the base frame. The size of the output frame is the same as the size of the through hole and the through slot.

[0010] Through the above technical solution, by cooperating with the through hole and through slot, the output frame can come into contact with the through hole and through slot when the hydraulic cylinder assembly is placed, which can play a preliminary positioning role. Then, with the addition of the pin, the hydraulic cylinder assembly can be fixed to the base frame.

[0011] Preferably, a lifting nut is fixedly installed at the end of the square tube frame 2 away from the base frame. There are two identical sets of lifting nuts, and two identical lifting nuts are provided in each set. The lifting nuts in each set are symmetrically distributed about the center line of the base frame. A square tube frame 3 is welded between the two square tube frames 2.

[0012] Through the above technical solution and the design of the lifting nut, when it is necessary to lift the entire tooling, the entire tooling can be lifted and transferred through the lifting nut, which can improve its versatility.

[0013] Preferably, the cylinder body is provided with a spraying end near the base frame, and the spraying end passes through the through hole and extends into the interior of the base frame.

[0014] Through the above technical solution, by cooperating with the spraying end and the through hole, when the spraying end contacts the through hole, the spraying end is located inside the base frame, which can protect the spraying end during spraying and prevent the machine head from being painted.

[0015] Preferably, the side of the base frame closest to the square tube skeleton is coated with a Teflon coating, and the positioning component is located between the base frame and the cylinder assembly.

[0016] The above technical solution can prevent paint splashes during the painting process from adhering to the base frame, enabling reuse. Furthermore, the positioning component is set between the base frame and the hydraulic cylinder assembly, serving as both a positioning reference surface for the hydraulic cylinder assembly and preventing coating wear caused by direct contact between the hydraulic cylinder assembly and the base frame, thus extending the service life of the tooling.

[0017] Preferably, the through groove, positioning component, hydraulic cylinder component and pin are in one-to-one correspondence, and the through groove, positioning component, hydraulic cylinder component and pin are provided in two identical sets, with each set having three identical through grooves, positioning components, hydraulic cylinder components and pins.

[0018] Through the above technical solution, the two sets of through slots, positioning components, hydraulic cylinder components and pins are symmetrically distributed. Each set contains three units and can clamp six hydraulic cylinder components at the same time for painting operations, which increases the single painting efficiency of the tooling to 6 times that of traditional single-station tooling, thereby improving its work efficiency.

[0019] Compared with the prior art, the present invention provides a tooling for painting hydraulic cylinders, which has the following advantages:

[0020] 1. This hydraulic cylinder painting fixture, through the cooperation of the spraying end and the through hole, can protect the spraying end from being sprayed during the subsequent spraying process by being located inside the base frame when the spraying end is in contact with the through hole. The Teflon coating design can prevent paint splashes from adhering to the base frame during the spraying process, allowing for reuse. Furthermore, the positioning component is set between the base frame and the hydraulic cylinder assembly, serving as both a positioning reference surface for the hydraulic cylinder assembly and preventing coating wear caused by direct contact between the hydraulic cylinder assembly and the base frame, thus extending the service life of the fixture.

[0021] 2. This hydraulic cylinder painting fixture allows the output frame to contact the through holes and through slots when the hydraulic cylinder assembly is placed, which serves as a preliminary positioning function. Subsequently, with the help of the pin, the hydraulic cylinder assembly can be fixed to the base frame. The two sets of through slots, positioning components, hydraulic cylinder assemblies and pins are symmetrically distributed, and each set contains three units. Six hydraulic cylinder assemblies can be clamped at the same time for painting operations, which increases the single painting efficiency of the fixture to 6 times that of traditional single-station fixtures, thereby improving its work efficiency.

[0033] Specifically, a caster 4 is provided at the end of the square tube frame 3 away from the base frame 1. The caster 4 is an all-iron high-temperature resistant caster. The advantage is that the square tube frame 3 and the square tube frame 2 5 are welded to form a three-dimensional support frame, which provides rigid vertical support for the base frame 1. The all-iron caster 4 is installed at the end of the square tube frame 3, which allows the tooling to move flexibly on the workshop floor. Moreover, the all-iron structure is not afraid of high temperatures when entering the spraying line.

[0034] Specifically, the hydraulic cylinder assembly 9 includes a hydraulic cylinder body 901. An output frame 903 is provided at one end of the hydraulic cylinder body 901 near the base frame 1. The size of the output frame 903 is the same as that of the through hole 803 and the through groove 7. The advantage is that, through the cooperation between the output frame 903 and the through hole 803 and the through groove 7, when the hydraulic cylinder assembly 9 is placed, the output frame 903 can contact the through hole 803 and the through groove 7, which can play a preliminary positioning role.

[0035] Specifically, a lifting nut 6 is fixedly installed at the end of the square tube frame 2 5 away from the base frame 1. There are two identical sets of lifting nuts 6, and two identical sets of lifting nuts 6 are provided. Each set of lifting nuts 6 is symmetrically distributed about the center line of the base frame 1. A square tube frame 3 11 is welded between the two square tube frames 2 5. The advantage is that, through the design of the lifting nut 6, when it is necessary to lift the whole tooling, the whole tooling can be lifted and transferred through the lifting nut 6, which can improve its versatility.

[0036] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0037] Specifically, a spraying end 902 is provided at one end of the cylinder body 901 near the base frame 1. The spraying end 902 passes through the through hole 803 and extends into the interior of the base frame 1. The advantage is that, through the cooperation between the spraying end 902 and the through hole 803, when the spraying end 902 contacts the through hole 803, the spraying end 902 is located inside the base frame 1, and then during spraying, it can protect the spraying end 902 and prevent the machine head from being painted.

[0038] Specifically, the side of the base frame 1 closest to the square tube frame 3 is coated with a Teflon coating. The positioning component 8 is located between the base frame 1 and the hydraulic cylinder assembly 9. The advantage is that it can prevent paint splashes during the painting process from adhering to the base frame 1, and can be reused. Furthermore, the positioning component 8 is located between the base frame 1 and the hydraulic cylinder assembly 9, serving as both a positioning reference surface for the hydraulic cylinder assembly 9 and preventing the coating from being worn due to direct contact between the hydraulic cylinder assembly 9 and the base frame 1, thus extending the service life of the tooling.

[0039] Specifically, the through slot 7, positioning component 8, hydraulic cylinder component 9, and pin 10 are in one-to-one correspondence. There are two identical sets of through slot 7, positioning component 8, hydraulic cylinder component 9, and pin 10. Each set has three identical through slot 7, positioning component 8, hydraulic cylinder component 9, and pin 10. The advantage is that the two sets of through slot 7, positioning component 8, hydraulic cylinder component 9, and pin 10 are symmetrically distributed. Each set contains three units, and six hydraulic cylinder components 9 can be clamped at the same time for painting operations. This increases the single painting efficiency of the tooling to 6 times that of traditional single-station tooling, thereby improving its work efficiency.

[0040] Working Principle: During use, square tube frame 1 (3) and square tube frame 2 (5) are welded to form a three-dimensional support frame, providing vertical rigid support for the base frame 1. All-iron casters 4 are installed at the ends of square tube frame 1 (3), allowing the tooling to move flexibly on the workshop floor. The all-iron structure is resistant to high temperatures when entering the spraying line. Through the cooperation of the output frame 903 with the through hole 803 and through groove 7, when placing the hydraulic cylinder assembly 9, the output frame 903 can contact the through hole 803 and through groove 7, providing initial positioning. The design of the lifting nut 6 allows the entire tooling to be lifted and transferred when needed, improving its versatility. Through the cooperation of the spraying end 902 with the through hole 803, when the spraying end 902 and the through hole... When contact is made with 803, the spraying end 902 is located inside the base frame 1. During spraying, the spraying end 902 is protected, preventing paint from splashing onto the base frame 1 and allowing for reuse. The positioning component 8 is located between the base frame 1 and the cylinder assembly 9, serving as a positioning reference surface for the cylinder assembly 9 and preventing coating wear caused by direct contact between the cylinder assembly 9 and the base frame 1, thus extending the tooling's service life. The two sets of through slots 7, positioning components 8, cylinder assemblies 9, and pins 10 are symmetrically distributed, with each set containing three units. Six cylinder assemblies 9 can be clamped simultaneously for painting operations, increasing the single-cycle painting efficiency of the tooling to six times that of traditional single-station tooling, thereby improving its work efficiency.
