Description

Technical Field

[0001] This utility model relates to the field of machining parts, and specifically to tooling for drilling and machining valve components. Background Technology

[0002] In general machining, for valve assemblies (see...) Figure 15-16 The main structure is a valve stem, with plastic washers and guide components installed inside. The valve assembly must be riveted after ensuring the assembly dimension H. In this case, it is generally impossible to machine riveting holes on the parts themselves. The guide component only has holes on one side. Therefore, after assembly, the valve stem and guide component must be drilled through using the existing holes in the guide component as a guide before riveting.

[0003] Therefore, in order to ensure the quality of parts processing, it is necessary to design a drill jig for the auxiliary drilling of valve components to perform supplementary processing on the valve components. Summary of the Invention

[0004] The purpose of this utility model is to provide a drilling jig for valve assembly drilling that is precise in positioning and easy to use. The jig includes a base, a spacer pin, a pressure block, a clamping screw, a rotating plate, a support pin, and a pressure pin rod. In the drilling jig, the spacer pin is installed in the base, and the valve assembly is clamped by a clamping structure consisting of the pressure block, clamping screw, rotating plate, and support pin. After drilling, the pin is installed into the valve assembly for riveting. The base has a limiting groove to restrict the rotational freedom of the parts after installation; the base also has a tool relief groove to avoid the drill bit shank during machining after valve assembly. The connection between the spacer pin and the base is an interference fit. After the spacer pin is installed in the base, the end face of the spacer pin is ground flat, and the height between the spacer pin and the base indirectly ensures the clamping dimensions of the valve assembly assembly. The clamping structure consists of the pressure block, clamping screw, rotating plate, and support pin. The pressure block and clamping screw, the clamping screw and rotating plate, and the support pin and base are all connected by threads. The pressure block has an internal slotted groove, allowing it to move up and down without rotating after the support screw is screwed in, thus preventing scratches on the end face of the parts. The clamping screw has a stepped smooth rod in the middle of its threaded shaft for easy screwing into the pressure block. The rotary plate is designed with double-sided U-shaped grooves for easy assembly and disassembly. The support pin is designed as a stepped shaft for easy connection with the U-shaped groove of the rotary plate, providing support. A small hole is provided at the end of the pressure pin rod; after drilling, the pin can be inserted into the hole, and the pressure pin rod, through the hole, inserts the pin into the valve assembly. Both ends are then riveted and secured.

[0005] The beneficial effects of this utility model are:

[0006] The drill jig provided by this utility model for drilling valve components is a precise and easy-to-use drill jig for drilling valve components. It uses the guide component in the valve component as the positioning reference and the clamping device clamps the valve component to completely restrict its degree of freedom. The original hole position of the guide component is used as the drilling reference after the valve component is assembled to drill the valve component. Moreover, it can allow the operator to quickly disassemble and assemble the drill jig while ensuring the quality of drilling the valve component, so that the valve component can be clamped and removed.

[0031] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art.

[0032] Please see Figure 1-14The figure shows a schematic diagram of a drill jig structure for drilling and machining a valve assembly provided by this utility model. It includes a base 1, a spacer pin 2, a pressure block 3, a clamping screw 4, a rotating plate 5, a support pin 6, and a pressure pin rod 7. The base 1 is provided with a hole 101 that passes through its top and bottom surfaces and is connected to the spacer pin 2 with an interference fit. A pair of holes 101 are symmetrically arranged on the top symmetrical line. A hole 102 that passes through its top and bottom surfaces is provided on the diagonal line of the top surface of the base 1 and is connected to the support pin 6. The base 1 is also provided with a hole 103 that passes through its top and bottom surfaces to place the valve assembly 8. The pressure block 3 is placed on top of the spacer pin 2. The clamping screw 4 passes through the center hole 501 of the rotating plate 5 and is connected to the pressure block 3. The rotating plate 5 has U-shaped grooves 502 at both ends that are sleeved on the support pin 6. The pressure pin rod 7 is provided with a hole 701. The base 1 is also provided with a limiting groove 104, which restricts the rotational freedom after the part is installed. The limiting groove 104 is located at the top of the third hole 103. The top surface of the base 1 is provided with a tool-relief groove 105. After the valve assembly 8 is assembled, it is machined to avoid the drill bit clamping shank. The bottom of the tool-relief groove 105 is rounded. There are two tool-relief grooves 105, which are perpendicular to the symmetrical line of the first hole 101. The spacer pin 2 includes an end 201 and a body 202. The body 202 is connected to the first hole 101, and the top of the end 201 is in contact with the pressure block 3. The pressure block 3 includes a hollow groove 301 and a pressure block threaded portion 302. The clamping screw 4 includes a clamping screw head 401, a first threaded portion 402, a first stepped smooth portion 403, and a second threaded portion 404. The second threaded portion 404 mates with the pressure block threaded portion 302 and passes through the hollow groove 301. The first stepped smooth portion 403 can pass through the pressure block threaded portion 302. The first threaded portion 402 mates with the center hole 501. The support pin 6 includes a second stepped smooth portion 601, a third threaded portion 602, and a milled flat portion 603. The second stepped smooth portion 601 mates with the U-shaped groove 502, and the third threaded portion 602 mates with the second hole 102. The support pin 6 is designed as a stepped shaft to facilitate connection with the U-shaped groove 502 of the rotating plate 5, thus providing support.

[0033] The base hole 102 is connected to the support pin thread 602, and the base hole 101 is interference-fitted with the spacer pin body 202. The valve assembly 8 is installed in the base hole 103. The guide flattening part B cooperates with the base limiting groove 104 to restrict the degree of rotation. The base relief groove 105 can avoid the drill bit chuck during drilling. The spacer pin 2 is interference-fitted with the base 1. After the spacer pin 2 is installed in the base 1, the end face of the spacer pin 201 is ground to indirectly ensure the valve assembly clamping size by using the height H between the spacer pin 2 and the base 1. After the clamping screw thread 404 is screwed into the pressure block thread 302, the clamping screw step smooth part 403 can enter the pressure block empty groove 301. After the clamping screw 4 is screwed in, the pressure block 3 can only move up and down and will not rotate to avoid scratching the end face of the valve assembly parts. The pressure block 3 and the clamping screw 4 can then be connected. The valve assembly 8 is assembled as a whole. During use, only tightening the clamping screw 4 is needed to clamp the valve assembly 8. The threaded part 402 of the clamping screw connects to the center hole 501 of the rotary plate. The head 401 of the clamping screw is knurled to increase friction during threaded connection. The double U-shaped grooves 502 on both sides of the rotary plate cooperate with the stepped smooth rod part 601 of the support nail to facilitate the assembly and disassembly of the valve assembly. The milled flat part 603 of the support nail facilitates tightening with a wrench during threaded connection. After the valve assembly 8 is assembled, the valve assembly is drilled with the original hole position of the guide component as a reference. Since there is a certain distance between the base 1 and the drilling position of the valve assembly 8, in order to ensure that the pin 801 can be inserted into the hole position after the riveting hole position of the valve assembly 8 is processed, a pressure pin rod 7 is designed. The rivet 801 can be connected to the small hole 701 at the end of the pressure pin rod by applying grease. The rivet 801 is pushed into the riveting hole position of the valve assembly 8 by the pressure pin rod 7.

[0034] Using the guide component in the valve assembly 8 as the positioning reference, the valve assembly is pressed and its degrees of freedom are completely restricted by the clamping device consisting of the pressure block 3, the clamping screw 4, the rotating plate 5, and the support nail 6. The original hole position of the guide component is used as the drilling reference for the valve assembly 8 after the valve assembly 8 is assembled. It can also allow the operator to quickly disassemble and assemble the drill jig while ensuring the quality of the drilling of the valve assembly 8, so that the valve assembly can be clamped and removed.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, are all covered within the scope of the claims of this utility model.
