DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0027] As shown in Figure 1 and Figure 2 , the clamp of the water valve cover in the embodiment comprises a fixed frame 1, the left and right of the fixed frame 1 are fixed with hole plates, and the fixed frame 1 can be installed on the drilling table through the hole plates, the front of the fixed frame 1 is fixed with two groups of side plates 4, the top of the side plate 4 is fixed with two counter plates 5 which are oppositely distributed, the top of the counter plate 5 is fixed with elastic pieces 6, the top third of the two elastic pieces 6 is outwardly inclined, and the two elastic pieces 6 are at a certain distance, so as to form a placement interval, the side plate 4 is further fixed with a positioning block 7 opposite to the placement interval, and the bottom is installed with a push-up cylinder 8, the piston rod of the push-up cylinder 8 is fixed with a push-up plate 9, and the end opposite to the positioning block 7 of the push-up plate 9 is fixed with a push-up block 10 which slides with the side plate 4.

[0028] In the above structure, the valve cover is pressed into the placement interval, in this process, the bottom of the valve cover will be attached to the outwardly inclined part of the elastic piece, so that the elastic piece can play a guiding role, and under the action of the guidance, the elastic piece will be extruded, and then cooperating with the toughness of the elastic piece, the valve cover can be quickly clamped and positioned, and two groups of clamps are installed on the fixed frame, when one group of clamps is drilling, the other group can be operated for feeding or discharging, so that the drilling machine can complete the feeding and discharging without stopping, thereby improving the efficiency;

[0029] When the valve cover is quickly positioned by the elastic piece, the push-up cylinder will push the push-up plate at this time, so as to drive the push-up block to be close to the valve cover, thereby playing a clamping role, and cooperating with the elastic piece can play a limiting and clamping role on the front, back, left and right of the valve cover, thereby improving the positioning firmness.

[0030] As shown in Figure 4The fixed frame 1 is further provided with two opposite side plates 16, the left side plate 16 is opposite to the left side of the left side pushing plate 9, and the right side plate 16 is opposite to the right side of the right side pushing plate 9, the top of the side plate 16 is rotatably connected with a hinge block 17, and the right side convex end is hingedly connected with a side pushing cylinder 19, the inner side of the hinge block 17 is fixedly connected with an upper pressing frame 18, and the right end of the upper pressing frame 18 is hingedly connected with the piston rod of the side pushing cylinder 19.

[0031] In combination with the above embodiment, when the valve cover is fixed, the side pushing cylinder pushes the upper pressing frame, and through the cooperation of the hinge block, the upper pressing frame can push the valve cover to be close to the top to play a role of downward pressing limiting, thereby improving the stability of positioning.

[0032] Further, the side opposite to the placement interval of the upper pressing frame is fixedly connected with two pressing columns. When the upper pressing frame is pressed downward, the top of the valve cover is pressed by the two pressing columns, and then the bottom surface of the upper pressing frame is close to the top of the valve cover, thereby improving the firmness of pressing.

[0033] As Figure 3 and 5 The fixed frame 1 is further provided with two opposite vertical plates 11, the top of the vertical plate 11 is rotatably connected with an upper top plate 13, and the bottom is hingedly connected with an upper top cylinder 12, the piston rod of the upper top cylinder 12 is hingedly connected with the left end of the upper top plate 13, and the upper top plate 13 is provided with a pressing plate 14.

[0034] In the above, the upper top plate is pushed up by the upper top cylinder, so that the bottom surface of the pressing plate is pressed downward until it is close to the valve cover shell, thereby limiting the upper side of the valve cover.

[0035] Further, the upper top plate 13 has two groups of positioning holes in an inclined state, each group of positioning holes has four positioning holes, and the pressing plate 14 is provided with locking holes matched with a single group of positioning holes. Therefore, the installation position of the pressing plate can be adjusted according to requirements.

[0036] Meanwhile, the bottom surface of the pressing plate 14 is fixedly connected with two rubber heads 15. The rubber heads are close to the outer side of the valve cover to limit the position, and can also reduce the contact with the outer side, thereby preventing damage to the outer side of the valve cover.

[0037] The bottom of the fixed frame 1 is provided with an upper pushing cylinder 2, the piston rod of the upper pushing cylinder 2 is fixedly connected with an upper pushing plate 3, the bottom of the upper pushing plate 3 is fixedly connected with two guide rods 20 penetrating through the fixed frame 1, the top of the upper pushing plate 3 is fixedly connected with two frame plates 21, the inner side of the frame plate 21 is provided with a linear module 22, the moving end of the linear module 22 is fixedly connected with a moving plate 23, one side of the moving plate 23 is fixedly connected with a sliding rod 24 slidingly connected with the top of the frame plate 21, and the head end of the opposite side of the two sliding rods 24 is fixedly connected with an upper plate 25.

[0038] In the initial state, the push-up cylinder is in the jacking state, and until the valve cover passes through the positioning, the linear module drives the slide rod to extend through the moving plate, so that the upper plate can be moved to the upper side of the other side of the valve cover, and then the push-up cylinder drives the push-up plate to retreat, so that the upper plate can be attached to the valve cover to limit the position, and in combination with the above, the left and right sides of the top of the valve cover can be limited to improve the stability.

[0039] In use, first, the two valve covers are inserted into the placement area respectively, so as to position the spring sheet, and then the jacking cylinder drives the jacking plate to attach the jacking block to the valve cover, under the cooperation of the positioning block, the valve cover can be clamped and positioned, so as to limit the front, back, left and right directions of the valve cover, then the side pushing cylinder drives the upper pressing frame to move down under the cooperation of the hinge block, the upper pressing frame drives the pressing column to press the valve cover, the linear module and the jacking cylinder operate simultaneously, the jacking cylinder drives the upper jacking plate, so that the pressing plate drives the rubber head to attach to the surface of the valve cover, and at the same time, the linear module drives the slide rod to push out through the moving plate, until the upper plate is located above the valve cover, at this time, the push-up cylinder drives the push-up plate to retreat, so that the upper plate is attached to the surface of the valve cover, so that the upper position of the valve cover can be limited, and the valve cover is prevented from being tilted left and right during the machining process to affect the drilling.

[0040] In summary, through automation, the clamping and positioning of the valve cover can be completed, the machining efficiency and quality are improved, and the valve cover can be fixed through two stations, so that the feeding and discharging can be completed without stopping.

[0041] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
