Description

Technical Field

[0001] The utility model belongs to the technical field of valve block processing, and in particular relates to a valve block clamping mechanism. Background Art

[0002] The valve block plays a vital role in the hydraulic system. It is mainly used to control the pressure, flow rate and flow direction of the fluid in the hydraulic system so that it can meet the requirements of different actions of various actuators. The valve block is a carrier for other hydraulic components and a channel body for oil circuit connection. It is a key component of the integrated hydraulic system. It generally adopts a rectangular shape and is made of aluminum or malleable cast iron. It is distributed with installation holes, oil holes, connection screw holes, positioning pin holes, common oil holes, connection holes, etc. related to the hydraulic valve. In order to ensure that the channels are correctly connected without interference, process holes are sometimes required. Therefore, when processing the valve block, six surfaces need to be processed.

[0003] At present, when processing valve blocks, a fixture with only a single clamp is usually used to clamp the valve block, and the direction of the valve block in the fixture is manually adjusted to ensure that each surface can be processed. The operation is cumbersome and the efficiency is low. Utility Model Content

[0004] Based on this, in order to solve the above technical problems, a valve block clamping mechanism is provided.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A valve block clamping mechanism, characterized by comprising:

[0007] A vertical track, on which an upper fixed block, an upper movable block, a lower movable block and a lower fixed block are arranged in sequence from top to bottom, the upper fixed block and the lower fixed block are both fixed on the track, the upper movable block and the lower movable block are both slidably arranged on the track, a vertical clamping opening for clamping a vertical valve block is formed between the upper fixed block and the upper movable block, a horizontal clamping opening for clamping a horizontal valve block is formed between the lower movable block and the lower fixed block, and a wedge-shaped opening is formed between the upper movable block and the lower movable block;

[0008] A wedge block is used for pressing into the wedge-shaped opening so that the vertical clamping opening and the horizontal clamping opening can respectively clamp the valve blocks they clamp.

[0009] The clamping mechanism of the utility model has two clamping openings, which can clamp two valve blocks in a vertical direction and a horizontal direction at the same time. After the three surfaces of the two valve blocks exposed outside the clamping openings are processed, the other three surfaces of the two valve blocks can be further processed by simply swapping the positions of the two valve blocks, and the valve blocks can be clamped by simply pressing in the wedge-shaped blocks. Compared with the prior art, the utility model is simple to operate and has high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments:

[0011] Figure 1 It is a structural schematic diagram of the utility model;

[0012] Figure 2 It is a cross-sectional view of the connection structure between the upper fixing block and the track of the present invention. DETAILED DESCRIPTION

[0013] The following will illustrate the implementation methods of the utility model in conjunction with the drawings in the specification. It should be noted that the implementation methods involved in this specification are not exhaustive and do not represent the only implementation methods of the utility model. The following corresponding embodiments are only for the purpose of clearly illustrating the utility model content of the utility model patent, and are not intended to limit its implementation methods. For ordinary technicians in this field, different forms of changes and modifications can be made on the basis of the description of this embodiment. All obvious changes or modifications that belong to the technical concept and utility model content of the utility model are also within the scope of protection of the utility model.

[0014] like Figure 1 As shown, the embodiment of the utility model provides a valve block clamping mechanism, including a vertical track 121 , an upper fixed block 122 , an upper movable block 123 , a lower movable block 124 , a lower fixed block 125 and a wedge block 126 .

[0015] The track 121 is fixed to the support column 3 by bolts, and an upper fixed block 122, an upper movable block 123, a lower movable block 124 and a lower fixed block 125 are arranged thereon in sequence from top to bottom. A vertical clamping opening for clamping the vertical valve block 2 is formed between the upper fixed block 122 and the upper movable block 123, a horizontal clamping opening for clamping the horizontal valve block 2 is formed between the lower movable block 124 and the lower fixed block 125, and a wedge-shaped opening is formed between the upper movable block 123 and the lower movable block 124, wherein the diameter of the vertical clamping opening is larger than the diameter of the horizontal clamping opening. Taking the vertical clamping opening as an example, the diameter refers to the distance between the upper fixed block 122 and the upper movable block 123.

[0016] The track 121 has scales, a vertical T-shaped groove 121 a is formed in the middle of the front side, and a first horizontal positioning tooth is formed on the surface of the front side.

[0017] The connection structures between the upper fixing block 122, the lower fixing block 125 and the track 121 are the same, and the upper fixing block 122 is used as an example for explanation below:

[0018] like Figure 2As shown, the back side of the upper fixed block 122 is connected to the slider 122a via a bolt 122b, one end of the bolt 122b passes through the front side of the upper fixed block 122 to the back side and is connected to the slider 122a, the slider 122a is slidably arranged in the T-slot 121a, a nut 122c is arranged at the other end of the bolt 122b, the upper fixed block 122 is locked on the track 121 by the nut 122c, and the precise position of the upper fixed block 122 on the track 121 can be adjusted up and down according to the scale by loosening the nut 122c, so as to adapt to valve blocks of different specifications.

[0019] The back side of the upper fixing block 122 has a second positioning tooth meshing with the first positioning tooth on the rail 121 to prevent the position of the upper fixing block 122 from shifting when the valve block is processed.

[0020] Of course, the position adjustment function of the upper fixing block 122 and the lower fixing block 125 may be omitted, and the upper fixing block 122 and the lower fixing block 125 may be directly fixed on the track. In this embodiment, the track 121 may not be provided with a tooth surface.

[0021] Similarly, the backs of the upper movable block 123 and the lower movable block 124 are respectively connected with a slider via bolts, and the slider is slidably arranged in the T-shaped groove 121a, and the backs of the upper movable block 123 and the lower movable block 124 also have second positioning teeth.

[0022] The wedge block 126 is used to press into the wedge opening so that the vertical clamping opening and the horizontal clamping opening can clamp the valve blocks they clamp respectively.

[0023] Unlike the upper fixed block 122 and the lower fixed block 125, the upper movable block 123 and the lower movable block 124 are not initially locked on the track 121 by nuts, and the second positioning teeth on the back are not engaged with the first positioning teeth, so that the upper movable block 123 and the lower movable block 124 can slide up and down on the track 121. After the wedge block 126 is pressed into the wedge-shaped mouth, the upper fixed block 122 and the lower fixed block 125 are locked on the track 121 by nuts. At this time, the second positioning teeth on the back of the upper fixed block 122 and the lower fixed block 125 are engaged with the first positioning teeth.

[0024] Before processing, the horizontal valve block and the vertical valve block are sequentially installed in the two clamping openings of the clamping mechanism 120. After the installation is completed, the wedge block 126 is pressed into the wedge-shaped opening so that the two clamping openings clamp the valve blocks respectively.

[0025] Among them, the valve block has a front side, a rear side, a left side, a right side, a top surface and a bottom surface. The valve block in the upper vertical clamping opening exposes the front side, left side and right side surfaces, and the valve block in the lower horizontal clamping opening exposes the rear side, top surface and bottom surface.

[0026] During processing, the valve block processing mechanism processes the three exposed surfaces of the upper valve block and the three exposed surfaces of the lower valve block. After completion, the positions of the upper and lower valve blocks in the clamping mechanism 120 are swapped, so that the valve block in the upper vertical clamping opening exposes the front side surface, the left side surface and the right side surface, and the valve block in the lower horizontal clamping opening exposes the rear side surface, the top surface and the bottom surface, and the valve block processing mechanism processes them again, thereby completing the processing of the six surfaces of each valve block.

[0027] From the above, it can be seen that the clamping mechanism provided in the embodiment of the utility model has two clamps, which can clamp two valve blocks in the vertical and horizontal directions at the same time. After the three surfaces of the two valve blocks exposed outside the clamps are processed, it is only necessary to swap the positions of the two valve blocks to further process the other three surfaces of the two valve blocks, and the valve blocks can be clamped by only pressing in the wedge block. Compared with the prior art, it is easy to operate and efficient.

[0028] In addition, the precise positions of the upper and lower fixed blocks on the track can be adjusted up and down according to the scale, making the adjustment convenient and accurate.

[0029] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
