Description

Technical Field

[0001] This utility model relates to the field of metal processing technology; more specifically, it relates to a fixture for processing fuel injection valves of internal combustion engines. Background Technology

[0002] The field of metal processing technology is a technical system that uses various processes and methods to perform forming, cutting, joining, surface treatment and other processing. By changing the shape, size, properties and surface state of metal materials, it can meet the functional, precision and quality requirements of parts or finished products in different industrial fields. A jig for processing fuel injection valves of internal combustion engines is often used in the field of metal processing technology. It is also used as a device to help patients with impaired hand function or those who need to recover their hand function to carry out rehabilitation training, improve hand flexibility and accelerate the recovery of hand function.

[0003] In response, Chinese patent application number CN213196615U discloses a flipping structure for machining, relating to the field of flipping structure technology. It addresses the problem that in existing raw material processing, workers typically flip the materials manually, which can easily lead to worker injuries due to errors. The stable base has a hydraulic support cylinder mounted on its upper end, a hydraulic push rod mounted on its upper end, a mounting base mounted above the hydraulic push rod, a placement seat mounted above the mounting base, fixed support seats mounted on both sides of the hydraulic support cylinder, a servo motor mounted above the fixed support seats, a rotating shaft mounted on one end of the servo motor, a flange connecting plate mounted on one end of the rotating shaft, a fixed connecting device mounted on one side of the flange connecting plate, a cylinder welding seat mounted on one side of the fixed connecting device, an electric cylinder mounted on one side of the cylinder welding seat, and a clamping seat mounted on one side of the pneumatic push rod.

[0004] 1. When using the above equipment, it is inconvenient to rotate metal parts, and it may be necessary to frequently stop the machine to adjust the position of the parts during the processing, which reduces the flexibility of the equipment to a certain extent.

[0005] 2. When using the above-mentioned equipment, most existing fuel injection valves have diverse sizes, and it may be necessary to replace them with other fixing fixtures for auxiliary fixation during processing. This operation is cumbersome and reduces processing efficiency. Therefore, we propose a fixture for processing fuel injection valves of internal combustion engines to solve the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fixture for machining the fuel injection valve of an internal combustion engine, so as to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a fixture for machining the fuel injection valve of an internal combustion engine, including a base.

[0008] Both sides of the upper end of the base are fixed with electric telescopic columns, and an adjustment column is slidably inserted inside the electric telescopic column. A motor is installed on one side of the upper end of the adjustment column, and a rotating block is fixed at the output end of the motor. An electric telescopic rod is installed at one end of the rotating block, and a clamping plate is fixed at one end of the electric telescopic rod.

[0009] Preferably, the rotating block slides inside the upper end of the adjusting column, and the use of the rotating block makes the electric telescopic rod more stable during use.

[0010] Preferably, the clamping plate has grooves on both the upper and lower ends near the middle of one end, and a cylinder is fixed inside the groove. An adjusting block is slidably fitted on the surface of the cylinder. Through the cooperation of the groove and the cylinder, when one end of the adjusting block is in contact with the surface of the fuel injection valve body, it fits more tightly to the surface of the fuel injection valve body.

[0011] Preferably, anti-slip pads are fixed on both sides of one end of the adjusting block. The use of anti-slip pads can increase the friction between the equipment and the fuel injection valve body, and prevent the fuel injection valve body from falling or shifting when clamped.

[0012] Preferably, the clamping plate has slidably inserted limiting posts at both the upper and lower ends, and there are multiple sets of limiting posts. One end of each limiting post is fixed with a spring. By using multiple sets of springs and limiting posts in combination, the position of the fuel injection valve body can be fixed.

[0013] Preferably, one end of the spring is fixed inside the clamping plate. By using the clamping plate and the spring together, the position of the spring can be restricted, preventing the spring from dislodging from the clamping plate when the limiting post moves.

[0014] Preferably, a placement platform is fixed at the upper middle position of the base, and a rubber pad is fixed at the upper end of the placement platform, so that the fuel injection valve body can be placed through the placement platform and the rubber pad.

[0015] Preferably, the two sets of clamping plates are attached to the side of each other with the injection valve body attached, and the operation process of the whole set of equipment can be completed through the injection valve body.

[0016] The technical effects and advantages of this utility model are as follows: This utility model moves the adjusting column by starting the electric telescopic column, and then moves the clamping plate inward or outward by starting the electric telescopic rod, thereby clamping the fuel injection valve body of different sizes. Then, the motor is started to make the rotating block drive the electric telescopic rod to rotate, and the fuel injection valve body rotates synchronously. This avoids the need to frequently stop the machine to adjust the position of the parts during the processing, and improves the flexibility of the equipment to a certain extent.

[0017] Two sets of clamping plates are brought closer to the fuel injection valve body, simultaneously driving multiple sets of adjusting blocks to fit against the surface of the fuel injection valve body. The angle of the adjusting blocks is automatically adjusted according to the shape of the fuel injection valve body, so that the surface of the anti-slip pad fits against the surface of the fuel injection valve body. Then, the spring's own elasticity drives the limiting post to support the fuel injection valve body, thereby fixing the position of the fuel injection valve body. The above operation avoids the need to change other fixing fixtures for auxiliary fixation during processing. At the same time, the above operation is relatively simple, thereby improving the processing efficiency of the equipment. Therefore, we propose a fixture for processing fuel injection valves of internal combustion engines to solve the above problems. Attached Figure Description

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The metal processing involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] like Figures 1 to 4As shown, this embodiment proposes a jig for processing the fuel injection valve of an internal combustion engine, including a base 1. Electric telescopic columns 2 are fixed on both sides of the upper end of the base 1, and an adjusting column 3 is slidably inserted inside the electric telescopic column 2. A motor 4 is installed on one side of the upper end of the adjusting column 3, and a rotating block 5 is fixed at the output end of the motor 4. An electric telescopic rod 6 is installed at one end of the rotating block 5, and a clamping plate 7 is fixed at one end of the electric telescopic rod 6. The rotating block 5 is slidably engaged inside the upper end of the adjusting column 3.

[0026] In this embodiment, the electric telescopic column 2 can be activated to move the adjusting column 3, thereby changing the height of the clamping plate 7 and the fuel injection valve body 14. The electric telescopic rod 6 can be activated to move the clamping plate 7 inward or outward, thereby clamping fuel injection valve bodies 14 of different sizes. Through the above operations, the ease of use of the equipment can be improved and the user's operation steps can be reduced, thus improving the effectiveness of the equipment to a certain extent. The motor 4 can be activated to make the rotating block 5 drive the electric telescopic rod 6, the clamping plate 7 and the fuel injection valve body 14 to rotate, thereby enabling the processing of other parts of the fuel injection valve body 14 and improving the practicality of the equipment.

[0027] Example 2

[0028] like Figure 3 and Figure 4 As shown, based on the same concept as the above embodiment, this embodiment also proposes: a groove is provided at both the upper and lower ends of one end of the clamping plate 7, and a cylinder is fixed inside the groove. An adjusting block 8 is slidably fitted on the surface of the cylinder. Anti-slip pads 9 are fixed on both sides of one end of the adjusting block 8. Limiting posts 10 are slidably inserted at both the upper and lower ends of the clamping plate 7, and multiple sets of limiting posts 10 are provided. A spring 11 is fixed at one end of the limiting post 10, and one end of the spring 11 is fixed inside the clamping plate 7. A placement platform 12 is fixed at the middle position of the upper end of the base 1, and a rubber pad 13 is fixed at the upper end of the placement platform 12. The fuel injection valve body 14 is attached to the side of the two sets of clamping plates 7 that are close to each other.

[0029] In this embodiment, by using the groove and cylinder together, when the adjusting block 8 is close to the surface of the fuel injection valve body 14, the direction of the adjusting block 8 can be adjusted according to the shape of the fuel injection valve body 14. At the same time, one end of the anti-slip pad 9 is made to fit with the surface of the fuel injection valve body 14, thereby fixing the position of the fuel injection valve body 14. By using the limiting post 10 and the spring 11 together, when the limiting post 10 is in contact with the position of the fuel injection valve body 14, the position of the fuel injection valve body 14 can be supported by the elastic force of the spring 11. This prevents the fuel injection valve body 14 from falling or shifting when it moves, thereby improving the stability of the equipment to a certain extent.

[0030] Working principle: When using the equipment, first place the fuel injection valve body 14 on the upper surface of the rubber pad 13. Then, start the electric telescopic rod 6 to move the clamping plate 7 closer to the position of the fuel injection valve body 14. When the position of the adjusting block 8 is close to the position of the fuel injection valve body 14, the adjusting block 8 can automatically rotate according to the shape of the fuel injection valve body 14, so that the surface of the anti-slip pad 9 is in contact with the surface of the fuel injection valve body 14. At the same time, through the cooperation of the limiting column 10 and the spring 11, the position of the fuel injection valve body 14 can be fixed. Then, start the electric telescopic column 2 to move the adjusting column 3 to a suitable height. Then, start the motor 4 to make the rotating block 5 drive the clamping plate 7 to rotate, thereby rotating the fuel injection valve body 14. This allows for the processing of other positions of the fuel injection valve body 14. The above is the complete working principle of this utility model.

[0031] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
