Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and more specifically, to a signal gear positioning and pressing tool. Background Technology

[0002] When installing the camshaft gear, signal disc, and camshaft of a diesel or gasoline engine, the camshaft gear and signal disc need to be assembled onto the camshaft. There are tolerance controls between the camshaft gear, signal disc, and camshaft to ensure the accuracy of the engine timing signal.

[0003] The camshaft gear, signal disc, and camshaft are installed manually. However, the quality of manual assembly is low, and it cannot effectively ensure that the positional accuracy and dimensional tolerances meet the requirements. This makes it impossible to guarantee the accuracy of the engine timing signal, which in turn affects the engine's ignition, power, and other performance characteristics. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the above-mentioned shortcomings of the prior art by providing a signal gear positioning and pressing tool that effectively controls the positional accuracy and dimensional tolerance of the assembly and improves the assembly quality.

[0005] The technical solution of this utility model is as follows: a signal gear positioning and pressing tool includes a mounting base, on which a camshaft gear base is provided, and a first cavity is provided on one side of the mounting base. A second cavity is provided on the camshaft gear base, and the second cavity is connected to the first cavity. A camshaft base is slidably provided in the second cavity. A return spring is provided in the first cavity. A camshaft gear positioning pin is detachably provided on the end face of the camshaft gear base.

[0006] As a further improvement, the other side of the mounting base is provided with a mounting groove, and the mounting groove is connected to the first cavity. The mounting base around the mounting groove is provided with mounting holes.

[0007] Furthermore, the first cavity is detachably provided with guide sleeves, and the reset spring is mounted on two guide sleeves.

[0008] Furthermore, the camshaft base is provided with a third cavity, which is connected to the second cavity, and the return spring is inserted into the third cavity.

[0009] Furthermore, a groove is provided on one side of the second cavity, and a bolt is threaded onto the camshaft base, with one end of the bolt slidably inserted into the groove.

[0010] Furthermore, a first limiting block is provided on the inner wall of the second cavity, and a second limiting block is provided on the outer wall of the camshaft base, wherein the width of the first limiting block is adapted to the width of the second limiting block.

[0011] Beneficial effects

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] 1. This utility model discloses a signal gear positioning and pressing tool, which achieves the positioning of the camshaft positioning pin and the camshaft gear through the camshaft positioning pin and the camshaft gear positioning pin. When a force is applied to the mounting base from left to right, the camshaft gear base moves to the right and the camshaft base slides to the left inside the camshaft gear base, thereby achieving the effect of pressing the camshaft gear into the camshaft. This effectively ensures the assembly quality between the camshaft gear, the signal disk, and the camshaft, and effectively controls its positional accuracy and dimensional tolerance.

[0014] 2. This utility model provides a signal wheel positioning and pressing fixture. This pressing tool can be manually pressed by workers or connected to devices such as cylinders and electric cylinders to achieve automated pressing, effectively expanding its application range.

Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0019] See Figure 1-2A signal gear positioning and pressing tool includes a mounting base 1, a camshaft gear base 2 mounted on the mounting base 1, and a first cavity 4 on one side of the mounting base 1. A second cavity 5 is mounted on the camshaft gear base 2, communicating with the first cavity 4. A camshaft base 3 is slidably mounted within the second cavity 5. A return spring 7 is located within the first cavity 4. When the bottom of the third cavity 6 within the camshaft base 3 is connected to one end of the return spring 7, the camshaft base 3 experiences a rightward elastic force. After the camshaft gear is pressed onto the camshaft using this pressing tool, the pressure applied to the mounting base 1 is removed, and the camshaft base 3 returns to its original position under the action of the return spring 7. A camshaft gear positioning pin 8 and a camshaft positioning pin 9 are detachably mounted on the end face of the camshaft gear base 5. The camshaft gear positioning pin 8 is inserted into the positioning hole of the camshaft gear, and the camshaft positioning pin 9 is inserted into the positioning hole of the camshaft, thereby achieving the positioning of the camshaft and the camshaft gear and effectively controlling the positional accuracy and dimensional tolerance between them. During installation, the camshaft gear is placed on the end face of the camshaft gear base 2, and the camshaft gear positioning pin 8 is inserted into the positioning hole of the camshaft gear. Then, the camshaft is fixed, and the camshaft positioning pin 9 is inserted into the positioning hole of the camshaft. A force is applied to the mounting base 1 from left to right. At this time, the camshaft gear base 2 moves to the right, and the camshaft base 3 slides to the left within the camshaft gear base 2, thereby achieving the effect of pressing the camshaft gear into the camshaft. This effectively ensures the assembly quality between the camshaft gear, the signal disc, and the camshaft, and effectively controls their positional accuracy and dimensional tolerance.

[0020] In this embodiment, the other side of the mounting base 1 is provided with a mounting groove 10, and the mounting groove 10 is connected to the first cavity 4. The mounting base 1 around the mounting groove 10 is provided with a mounting hole 11. The mounting hole 11 can be a threaded hole, and a fastening bolt can be threaded into it. The mounting base 1 can be fixedly installed on a workbench or cylinder and other equipment by the mounting groove 10 and the mounting hole 11 cooperating.

[0021] In this embodiment, a guide sleeve 12 is detachably provided inside the first cavity 4, and a return spring 7 is installed on the guide sleeve 12. The guide sleeve 12 is detachably installed inside the first cavity 4, which facilitates the disassembly of the guide sleeve 12 by workers, thereby facilitating the maintenance or replacement of the return spring 7.

[0022] In this embodiment, the camshaft base 3 is provided with a third cavity 6, which is connected to the second cavity 5, and the return spring 7 is inserted into the third cavity 6. When the bottom of the third cavity 6 in the camshaft base 3 is connected to one end of the return spring 7, the camshaft base 3 is subjected to a rightward elastic force. After the camshaft gear is pressed into the camshaft by the pressing tool, the pressure applied to the mounting base 1 is removed, and the camshaft base 3 is reset under the action of the return spring 7.

[0023] In this embodiment, a groove 14 is provided on one side of the second cavity 5, and a bolt 15 is threadedly connected to the camshaft base 3. One end of the bolt 15 is slidably inserted into the groove 14. When the camshaft base 3 slides in the second cavity 5, the bolt 15 plays a guiding role. Preferably, when the pressing tool is idle, the bolt 15 can be tightened through the mounting groove 10 to prevent the camshaft base 3 from sliding.

[0024] In this embodiment, a first limiting block 13 is provided on the inner wall of the second cavity 5, and a second limiting block 16 is provided on the outer wall of the camshaft base 3. The width of the first limiting block 13 is adapted to the width of the second limiting block 16, and the end face of the first limiting block 13 contacts the end face of the second limiting block 16 to restrict the sliding of the camshaft base 3 and prevent the camshaft base 3 from sliding out of the second cavity 5.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
