Description

Technical Field

[0001] The utility model relates to the technical field of valve processing, in particular to a side-top tooling oriented by a slider. Background Art

[0002] When producing some valve body parts, after the valve body is roughly cast, it often involves machining processes such as milling grooves or drilling. The T-shaped valve body is a common type of valve. Such a valve body usually includes a straight pipe and a side pipe. The two ends of the straight pipe are respectively a water inlet end and a control end, and the side pipe provided with a water outlet port is vertically connected to the middle position of the straight pipe and the water outlet port is controllably communicated with the water inlet port. When fixing the valve body before processing, it is usually clamped and fixed from its water inlet end and control end. On this basis, in order to prevent the valve body from rotating and shifting during the processing, it is also necessary to limit the orientation at its water outlet end.

[0003] Currently, when the commonly used processing device orients the water outlet end of the valve, as Figure 4 shown, it usually adopts the method of clamping the rough surface of the water outlet end from both sides. Because the outer surface of the valve usually needs to undergo subsequent processing procedures such as cutting, grinding, and polishing, the size of its outer rough surface is often not as standard and regular as the inner through hole. During mass production, the dimensional differences of the rough surfaces of different parts will cause orientation angle errors at the water outlet end when fixing the valve body. The positions and sizes of milling grooves or drilling on the valve body are very unstable, resulting in many finished products not meeting the drawing requirements, increasing the inspection requirements and inspection difficulty of the finished products, and affecting the production quality and efficiency. Chinese Patent Publication No. CN116372612A, with the publication date of July 4, 2023, and the name of "A Valve Positioning Tooling and a Valve Processing Method" discloses a valve positioning tooling, which includes a housing. A frame is installed inside the housing, a lifting mechanism is installed inside the frame, and a clamping mechanism is provided at the top of the lifting mechanism. The valve body can be clamped and fixed by using the lifting mechanism and the clamping mechanism together. However, the orientation method of this device for the water outlet end of the valve body is to clamp it on the outer rough surface of the valve, and the orientation accuracy is easily affected by the shape differences and dimensional errors of the rough surface. Summary of the Utility Model

[0004] The utility model overcomes the problems that the orientation accuracy of the water outlet end of the valve body is easily affected by the shape and size of the outer rough surface when fixing valve body parts by the existing fixture device, and provides a side-top tooling oriented by a slider. By using a clamping and positioning component to clamp and fix the water inlet end and control end of the valve body, and using a sliding orientation component to limit and fix the water outlet end of the valve body from the inside, the clamping and fixing and efficient orientation of valve body parts can be realized, the processing efficiency and processing accuracy can be improved, and the influence of the position of the water outlet end of the valve body and the dimensional differences of the rough surface on the orientation accuracy can be avoided.

[0005] In order to achieve the above purpose, the utility model adopts the following scheme:

[0011] Preferably, there are a pair of guide rods. Through holes corresponding to the pair of guide rods are respectively arranged on the slider. The guide rods pass through the through holes so that the slider is slidably connected to the pair of guide rods.

[0012] Preferably, the fixed clamping part includes:

[0013] A positioning plate, which is vertically fixed on the base plate;

[0014] A positioning column, one end of which is fixedly connected to the inner side of the positioning plate and the other end tops against the water inlet end of the T-shaped valve body.

[0015] Preferably, the positioning column and the positioning plate are detachably connected by bolts. The end of the positioning column extends into the water inlet hole at the water inlet end of the T-shaped valve body.

[0016] Preferably, the telescopic clamping part includes a cylinder fixing plate vertically fixed on the base plate. A cylinder is fixed on the cylinder fixing plate. A connecting block is arranged at the movable end of the cylinder and tops against the control end of the T-shaped valve body.

For example, they can be fixedly connected and set, or detachably connected and set, or integrally connected and set.

The orientation or positional relationship indicated by the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0030] As Figures 1-3 shown, the side top tooling oriented by a slider provided by the present invention includes:

[0031] A bottom plate 1; the bottom plate 1 can be set as a square plate, and is fixed on the equipment workbench by pressing with accessories during use, serving as a platform for installing other clamping components and providing a space for valve body processing operations.

[0032] A clamping and positioning assembly, which includes a fixed clamping part and a telescopic clamping part oppositely arranged on the bottom plate 1, used to respectively press against the horizontally coaxial water inlet end 21 and control end 22 of the T-shaped valve body, so as to realize the clamping of the T-shaped valve body; the fixed clamping part and the telescopic clamping part are oppositely arranged, generally fixed at both ends of the bottom plate 1 respectively. The fixed clamping part includes a part connected and fixed to the bottom plate 1 and a part in contact with the T-shaped valve body for positioning. Among them, the part connected to the bottom plate 1 can use structures such as columns or plates extending upward, and the part in contact with the water inlet end 21 of the T-shaped valve body has a certain height from the bottom plate 1 to provide sufficient space for placing the valve body parts; the telescopic clamping part includes a part connected and fixed to the bottom plate 1 and a part in contact with the control end 22 of the T-shaped valve body for pressing. Among them, the part connected to the bottom plate 1 can use structures such as columns or plates extending upward, and the part in contact with the T-shaped valve body can use telescopic parts such as hydraulic rods and threaded rods that can be telescoped or rotated and advanced and maintain their lengths to realize the tightening and fixing of the T-shaped valve body.

[0033] Sliding orientation component, which includes a slide rail disposed on the base plate 1 between the fixed clamping portion and the telescopic clamping portion and parallel to the axes of the water inlet end 21 and the control end 22 of the clamped T-shaped valve body, a slider 3 disposed on the slide rail, and an orientation pin 4 disposed on the slider 3. The orientation pin 4 is used to abut in the water outlet hole of the water outlet end 23 of the T-shaped valve body. When the T-shaped valve body is positioned and fixed by the clamping and positioning component, its water inlet end 21 and control end 22 are not easily detached or shaken under pressure. However, if the orientation of its water outlet end 23 is not restricted, there may be an initial deviation between the extending direction of the water outlet end 23 of the valve body and the vertical direction, or rotational deviation may occur due to uneven stress during the processing. Therefore, the sliding orientation component is used to orient the water outlet end 23 of the valve body. The orientation pin 4 extends into the water outlet hole of the water outlet end 23 of the valve body and fits tightly with it. The orientation pin 4 connected to the slider 3 can slide back and forth along the axes of the water inlet end 21 and the control end 22 of the T-shaped valve body through the slide rail, and move and cooperate according to the horizontal distance between the water outlet end 23 and the water inlet end 21 of the valve body. Moreover, the orientation pin 4 can only slide along the direction of the slide rail, without generating side slip and shaking in a biased direction. As Figure 4 shown, in the prior art, the common method of fixing the water outlet end 23 with nuts from both blank surfaces requires repeatedly adjusting the nuts on both sides to orient the water outlet end 23 to a suitable angle. The operation is troublesome and it is difficult to guarantee the adjustment accuracy. However, when using the orientation pin 4 for orientation, only need to sleeve the water outlet end 23 of the valve body on the orientation pin 4. The operation is simple and efficient. And because the precision of the through hole in the valve body is generally high and stable, the orientation accuracy of the orientation pin 4 for the water outlet end 23 can be maintained at a relatively high level.

[0034] When using this device to fix and process the T-shaped valve body, first retract the telescopic member of the telescopic clamping portion to the shortened state, orient the water inlet end 21 and the control end 22 of the T-shaped valve towards the fixed clamping portion and the telescopic clamping portion of the clamping and positioning component respectively, align and sleeve the water outlet end 23 of the T-shaped valve on the orientation pin 4. Utilize the orientable sliding characteristic of the sliding orientation component to move the T-shaped valve closer and abut it against the fixed clamping portion, and then extend the telescopic member of the telescopic clamping portion until it abuts tightly against the valve control end 22 to achieve clamping and fixing of the T-shaped valve. At this time, the positioning and orientation of the T-shaped valve are completed. After milling slots or drilling holes and other processing operations, loosen the telescopic clamping portion and translate the T-shaped valve away from the fixed clamping portion and then take it out upward, and then the next T-shaped valve body can be replaced for processing.

[0035] This device orients the valve body from the inside of the water outlet end 23. The orientation pin 4 cooperates with the water outlet hole of the water outlet end 23 to orient the valve body with high precision, avoiding the precision error of orienting using the rough surface of the valve body and ensuring the quality stability of valve body processing. By sliding the slider 3 in the slide rail to adjust the position of the orientation pin 4, when processing different valve bodies, even if the distance between the water outlet end 23 and the water inlet end 21 and the control end 22 varies due to different models, the orientation pin 4 can be quickly moved directly below the water outlet end 23 for cooperation. And when facing a valve body with a shorter water outlet end 23, only an extended orientation pin 4 needs to be inserted into the water outlet hole for accurate orientation. It is not only fast and accurate in orientation, but also applicable to the fixed processing of a variety of different T-shaped valve bodies. Through the cooperation of the slide rail and the slider 3, the T-shaped valve body can be conveniently and accurately placed on the device and can be quickly removed, with convenient operation, avoiding the adjustment operation of locking the water outlet end 23 with nuts and improving the processing efficiency of valve body parts.

[0036] In another technical solution, as Figure 3 shown, the slide rail includes a pair of guide rod fixing plates 5 and guide rods 6 arranged between the pair of guide rod fixing plates 5. The guide rods 6 are arranged along a direction parallel to the axes of the water inlet end 21 and the control end 22 of the clamped T-shaped valve body. The two guide rod fixing plates 5 are respectively arranged at positions close to the fixed clamping part and the telescopic clamping part. The extending direction of the guide rods 6 is the axial direction of the water inlet end 21 and the control end 22 of the T-shaped valve body and the rod body is horizontal. The bottom of the slider 3 can be set to fit on the bottom plate 1 or a square rod can be used so that the slider 3 can slide along the guide rods 6 without relative rotation. The guide rail fixing plate 5 can also limit the extreme sliding distance of the slider 3.

[0037] There are a pair of the guide rods 6. Through holes corresponding to the pair of guide rods 6 are provided on the slider 3. The guide rods 6 pass through the through holes so that the slider 3 is slidably connected to the pair of guide rods 6. The paired guide rods 6 are horizontally arranged in parallel. By cooperating with the pair of through holes and the guide rods 6, while ensuring the normal sliding of the slider 3, the restriction on the rotation and shaking of the slider 3 is enhanced, making the connection structure more stable.

[0038] In another technical solution, as Figure 2 shown, the fixed clamping part includes:

[0039] A positioning plate 7, which is vertically fixed on the bottom plate 1;

[0040] A positioning column 8, one end of which is fixedly connected to the inner side of the positioning plate 7 and the other end abuts against the water inlet end 21 of the T-shaped valve body.

[0041] The positioning posts 8 on the positioning plate 7 extend horizontally and have a certain height distance from the bottom plate 1. The structure of the positioning posts 8 is designed such that part of them extends into the water inlet of the T-shaped valve body for positioning and fixing, or the positioning posts 8 are designed in a perforated shape, and part of the water inlet of the T-shaped valve body extends into the holes for fixing. When using the positioning posts 8 to position and fix the T-shaped valve body, there is sufficient longitudinal space for the water outlet end 23 of the T-shaped valve body to extend downward.

[0042] The positioning posts 8 and the positioning plate 7 are detachably connected by bolts, and the ends of the positioning posts 8 extend into the water inlet holes of the water inlet end 21 of the T-shaped valve body. The positioning posts 8 are detachably connected to the inner side of the positioning plate 7. For different models of T-shaped valve bodies, multiple positioning posts 8 with different size specifications can be designed, and different positioning posts 8 can be selected and installed according to different models of T-shaped valve bodies to achieve an adaptive positioning effect.

[0043] In another technical solution, as Figure 2 shown, the telescopic clamping part includes a cylinder fixing plate 9 vertically fixed on the bottom plate 1. A cylinder 10 is fixed on the cylinder fixing plate 9, and a connecting block 11 is arranged at the movable end of the cylinder 10 and abuts against the control end 22 of the T-shaped valve body. Preferably, the cylinder 10 is fixed on the outer side of the cylinder fixing plate 9 with the movable end facing inwards, and through holes are provided on the cylinder fixing plate 9. After the movable end of the cylinder 10 passes through the through holes, the connecting block 11 abuts against the control end 22 of the T-shaped valve body.

[0044] An elastic pressing block 12 is arranged at the position where the connecting block 11 contacts the T-shaped valve body. Conventional clamps use rigid connecting parts to directly contact the valve body parts, while adding the elastic pressing block 12 can make the force on the end of the T-shaped valve body more uniform, provide a buffering effect and make the clamping state of the T-shaped valve body more stable and reliable. The elastic pressing block 12 can be selected as a nylon pressing block or other elastic material blocks according to actual needs.

[0045] A reinforcing rod 13 is connected between the fixed clamping part and the telescopic clamping part. The reinforcing rod 13 is horizontally arranged on the sides of the fixed clamping part and the telescopic clamping part to connect and reinforce them, ensuring the structural stability and firmness of the device and the safety of the processing operation.

[0046] In another technical solution, as Figure 3 shown, the detachable structure is adopted for connecting the orientation pin 4 and the slider 3. By choosing to use a detachable orientation pin 4, its size specifications can be changed to be applicable to T-shaped valve bodies with different calibers, facilitating the use of the device in the processing of valve bodies of different batches and models. The detachable structure can adopt methods such as snap connection or threaded connection. When the type of the processed valve body changes, only the size of the orientation pin 4 needs to be replaced for matching, and there is no need to additionally configure a whole set of clamping devices, saving production costs and being simple and efficient to handle.

[0047] The detachable structure is a threaded connection structure. A vertical threaded hole is provided on the slider 3, and a stud for cooperating with the threaded hole is provided at the lower end of the alignment pin 4. The water outlet hole of the T-shaped valve is generally a circular groove hole, and the alignment pin 4 is a circular cylinder. When installing the alignment pin 4 onto the slider 3, the screwing degree of the stud will not affect the cooperation between the alignment pin 4 and the water outlet end 23 of the valve.

[0048] The number of devices and the processing scale described here are used to simplify the description of the present utility model. Applications, modifications, and variations of the present utility model will be apparent to those skilled in the art.

[0049] Although the embodiments of the present utility model have been disclosed as above, it is not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present utility model. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present utility model is not limited to the specific details and the illustrated examples described herein.
