Description
Technical Field
[0001] This utility model relates to a deep hole machining device, and more particularly to a deep hole machining device for an injector body. Background Technology
[0002] With social and economic development, current machining technology is quite mature. The focus of competition has shifted to improving efficiency and saving costs through optimized production processes. Most precision machine tools require corresponding positioning and clamping fixtures based on different product designs to meet processing requirements. For the same machine tool, different fixture designs determine processing efficiency and production quality. For example, when machining deep oil holes on injector bodies on a gun drill, due to the different inlet and outlet angles, each hole needs to be adjusted to a horizontal position using fixtures before machining. Gun drills operate on four axes simultaneously, and considering the machining errors of the fixtures themselves, each machining operation requires adjusting the fixture and machine tool to ensure each axis meets angle and dimensional requirements before each operation. This necessitates continuous fine-tuning to accurately locate the position, resulting in lengthy and unstable adjustments that waste machine work. Therefore, finding a simple and quick way to adjust fixture clamping to improve production efficiency and product quality is a pressing issue that needs to be addressed. Utility Model Content
[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a deep hole machining device for fuel injector bodies.
[0004] To solve the above technical problems, the technical solution adopted by this utility model is: a deep hole machining device for an injector body, including a machine tool and a base plate set on the table of the machine tool. The base plate is equipped with a clamping component that can be dynamically adjusted and is located on the corresponding side of the machine tool in the latitudinal direction. The machine tool is sequentially connected to a fixed seat and a front top plate facing the clamping component. A guide rod with its other end dynamically connected to a support block is connected to the front top plate. An adjusting block is dynamically adjusted and connected directly above the support block. The adjusting block supports the injector body. A second cylinder for longitudinal clamping is set directly above the injector body.
[0005] Furthermore, the clamping assembly includes a small base plate, and an adjusting hole is provided on the connecting surface of the small base plate to facilitate the passage of the positioning bolt. A shim is inserted between the bolt head of the positioning bolt and the top surface of the outer ring of the adjusting hole.
[0006] Furthermore, the clamping assembly also includes a first cylinder and a top plate disposed at the output end of the first cylinder, wherein the first cylinder drives the top plate to clamp the injector body in the latitudinal direction.
[0007] Furthermore, the side of the washer that contacts the bolt head of the positioning bolt forms a lifting slope, and the washer also has an open opening that matches the diameter of the positioning bolt.
[0008] Furthermore, the end face of the front top plate facing the clamping component forms a positioning slope, and the front top plate also has a fixing hole for an interference fit guide rod.
[0009] Furthermore, the support block forms a support body and side walls extending upward on both sides of the support body.
[0010] Furthermore, the support body has a guide hole for accommodating the guide rod, and a locking hole that is in the same plane as the guide hole and perpendicular to the extension line of the guide hole.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0025] like Figure 1-8 As shown in the figure, this embodiment of the deep hole machining device for the injector body includes a machine tool 11 and a base plate 1 set on the table of the machine tool 11. The base plate 1 exists in the form of a worktable and a connecting table. The base plate 1 is equipped with a clamping component 2 that can be dynamically adjusted and is located on the corresponding side of the machine tool 11 in the latitudinal direction. That is, the action of the clamping component 2 is completed in the latitudinal direction. The machine tool 11 is sequentially connected to a fixed seat 12 facing the clamping component 2 and a front top plate 13. The front top plate 13 is connected to a guide rod 16 that is dynamically connected to a support block 17 at the other end. An adjusting block 24 is dynamically adjusted and connected directly above the support block 17. The adjusting block 24 supports the injector body 29. A second cylinder 27 for longitudinal clamping is set directly above the injector body 29. That is, the action of the second cylinder 27 is completed in the longitudinal direction. In summary, this embodiment has the ability to position and clamp the injector body 29 in both directions.
[0026] like Figure 2 As shown, the clamping assembly 2 includes a small base plate 1. An adjustment hole 6 is provided on the connecting surface of the small base plate 1 to facilitate the passage of the positioning bolt 7. The opening direction of the adjustment hole 6 is as follows: Figure 2As shown, the positioning bolt 7 has adjustment space within the adjusting waist hole 6, which facilitates precise adjustment of the left and right positions of the clamping component 2 during initial positioning. A shim 8 is inserted between the bolt head of the positioning bolt 7 and the top surface of the outer ring of the adjusting waist hole 6. The shim 8 is used to lift the bolt head of the positioning bolt 7. Lifting the bolt head of the positioning bolt 7 means that the shim 8 changes the depth to which the positioning bolt 7 can penetrate downwards through its thickness, thereby changing the degree of connection between the small base plate 1 and the base plate 1, and thus lifting the clamping component 2, playing a role in fine-tuning the center of the clamping component 2.
[0027] Based on this, the clamping assembly 2 also includes a first cylinder 4 and a top plate 5 disposed at the output end of the first cylinder 4. The first cylinder 4 is implemented by driving the top plate 5 to press the injector body 29 in the latitudinal direction. In combination with the above structure, the shim 8 is used for fine adjustment according to the specific ejection direction of the top plate 5, so that the top plate 5 can be aligned with the center of the injector body 29.
[0028] like Figure 3-4 As shown, the side of the gasket 8 that contacts the bolt head of the positioning bolt 7 forms a lifting slope 9. The gasket 8 also has an open opening 10 that matches the diameter of the positioning bolt 7. Thus, after the gasket 8 lifts the positioning bolt 7 through its lifting slope 9, it has an inclination as formed by the lifting slope 9, which changes the clamping assembly 2, especially the inclination of the top plate 5, to ensure the consistency of the center alignment between the top plate 5 and the injector body 29.
[0029] like Figure 5 As shown, the end face of the front top plate 13 facing the clamping assembly 2 forms a positioning slope 14. The positioning slope 14 is used to keep the deep hole to be processed in a horizontal position, such as... Figure 6 As shown, the front top plate 13 also has a fixing hole 15 for an interference fit guide rod 16. In this embodiment, there are two fixing holes 15, so there are also two guide rods 16.
[0030] like Figure 7 As shown, the support block 17 forms a support body 18 and side walls 20 extending upward on both sides of the support body 18. The support body 18 has guide holes 21 for accommodating guide rods 16. In this embodiment, there are two guide rods 16, so there are also two guide holes 21. The support body 18 also has locking holes 30 that are on the same plane as the guide holes 21 and perpendicular to the extension lines of the guide holes 21. When the guide rod 16 passes through the guide hole 21 to reach the designated positioning and clamping position, a bolt is inserted into the locking hole 30 so that the end of the bolt abuts against the guide rod 16 and restricts its displacement, thereby locking the guide rod 16. In addition, the top surface of the support body 18 between the two side walls 20 is the bottom surface 19.
[0031] like Figure 7As shown, a number of fine adjustment holes 22 are provided on one side wall 20, and the fine adjustment holes 22 are arranged in a line along the side wall 20. Fastening holes 23 are provided on the other side wall 20.
[0032] The adjusting block 24 is fitted between the two side walls 20. The outer side of the adjusting block 24 forms a wedge-shaped slope 25 that matches the fine-tuning hole 22. The adjusting block 24 can change its vertical position within the support block 17 under external force. Specifically, an external positioning bolt extends through the fine-tuning hole 22 and abuts against the wedge-shaped slope 25 of the adjusting block 24. By changing the depth of the positioning bolt, it abuts against the upper side of the wedge-shaped slope 25. The deeper the positioning bolt goes, the closer the end of the positioning bolt is to the inflection point between the upper and lower sides of the wedge-shaped slope 25. During this process, the adjusting block 24 moves vertically upward, thereby changing the vertical position of the injector body 29 supported in the adjusting block 24.
[0033] The second cylinder 27 is connected to the adjusting block 24 via the cylinder fixing plate 26. Specifically, it is connected to the fastening hole 23 by bolts passing through the cylinder fixing plate 26. The output end of the second cylinder 27 is provided with a pressure head 28 facing the injector body 29. The pressure head 28 is driven by the second cylinder 27 to press the injector body 29 radially.
[0034] This application discloses a deep hole machining device for fuel injector bodies. This device can be used with a gun drill. The entire device is easy to adjust. After the initial machining, leveling, and locking, it is cured and does not need to be disassembled. In subsequent machining, the entire device can be directly installed on the machine tool for machining without the need to readjust the tooling position, saving the installation and adjustment time for each machining. It adopts an automatic cylinder positioning and tightening method, which improves the efficiency of machine adjustment and greatly reduces the scrap of machine adjustment. At the same time, for fuel injector bodies with different diameters and oil hole angles, only the shim 8, the front top plate 13 and / or the angle need to be adjusted, and the adjustment block 24 needs to be replaced to adjust the positioning diameter. The rest of the parts can be reused, which has great practicality.
[0035] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
