Oxygen sensor chip spraying tooling

Abstract

This utility model discloses an oxygen sensor chip spraying fixture, relating to the field of oxygen sensor chip processing technology. It includes a fixture body and an oxygen sensor chip. A fixing block is provided on one side of the fixture body, and chip fixing slots are formed on the sides of the fixing block and the fixture body that are close to each other. This oxygen sensor chip spraying fixture facilitates the fixation of the oxygen sensor chip through the cooperation of the fixing block, the fixture body, and the chip fixing slots. Through the cooperation of a spring, a T-shaped sliding rod, and a ceramic plug, the spring force pushes the T-shaped sliding rod to move, thereby inserting the ceramic plug into a small hole on the oxygen sensor chip. This prevents the small hole from being blocked by sprayed powder during the spraying process, effectively improving the pass rate of oxygen sensor chip spraying. Furthermore, its simple structure and low production cost enhance the practicality of this oxygen sensor chip spraying fixture.

Description

Technical Field

[0001] This utility model relates to the field of oxygen sensor chip processing technology, specifically to oxygen sensor chip spraying fixtures. Background Technology

[0002] An oxygen sensor is a sensor that detects the oxygen concentration in the air. The oxygen sensor chip is one of the core components of the oxygen sensor. During the processing of the oxygen sensor chip, it needs to be sprayed. However, because there is a small hole on the top of the oxygen sensor chip, the sprayed powder often blocks the hole during the spraying process, resulting in a large number of defective products that need to be reworked. In response to this situation, we have proposed an oxygen sensor chip spraying fixture. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an oxygen sensor chip spraying fixture, which solves the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an oxygen sensor chip spraying fixture, comprising a fixture body and an oxygen sensor chip, wherein a fixing block is provided on one side of the fixture body, and chip fixing grooves are formed on the side of the fixing block that is close to the fixture body, and the oxygen sensor chip is placed in the inner cavity of the chip fixing groove. A through groove is provided on the top of the other side of the tooling body. A T-shaped sliding rod is slidably sleeved in the inner cavity of the through groove. A spring is movably sleeved on the surface of the T-shaped sliding rod. A limit bolt is threaded on the inner cavity of the other end of the T-shaped sliding rod. One end of the limit bolt extends to the outside of the tooling body. A fixing hole is provided in the middle of the T-shaped sliding rod, and a ceramic plug is installed in the inner cavity of the fixing hole.

[0005] Preferably, the tooling body has screw holes on one side and on both sides of the chip fixing slot, and two fixing screws are threaded on the fixing block, with one end of the fixing screw threaded into the inner cavity of the screw hole.

[0006] Preferably, one end of the spring abuts against the side of the tooling body and one end of the T-shaped sliding rod.

[0007] Preferably, the diameter of the nut at the end of the limiting bolt is larger than the diameter of the through groove.

[0008] Preferably, the oxygen sensor chip has a small hole, and the ceramic plug passes through the small hole on the oxygen sensor chip and is adapted to the inner diameter of the small hole.

[0009] Preferably, the tooling body has mounting holes.

[0010] This utility model provides a spray coating fixture for oxygen sensor chips, which has the following beneficial effects: This oxygen sensor chip coating fixture facilitates the fixation of the oxygen sensor chip through the cooperation of a fixing block, the fixture body, and the chip fixing slot. A spring, a T-shaped sliding rod, and a ceramic plug are used in conjunction. The spring force pushes the T-shaped sliding rod to move, thereby inserting the ceramic plug into a small hole on the oxygen sensor chip. This prevents the small hole from being blocked by the coating powder during the coating process, effectively improving the pass rate of oxygen sensor chip coating. Furthermore, its simple structure and low production cost enhance the practicality of this oxygen sensor chip coating fixture. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example 1: Refer to Figures 1-3 This utility model provides an oxygen sensor chip spraying fixture, including a fixture body 4 and an oxygen sensor chip 5. A fixing block 6 is provided on one side of the fixture body 4. Chip fixing grooves 8 are formed on the side of the fixing block 6 that is close to the fixture body 4. The oxygen sensor chip 5 is placed in the inner cavity of the chip fixing groove 8. A through groove 12 is provided on the top of the other side of the fixture body 4. A T-shaped sliding rod 2 is slidably sleeved inside the through groove 12. A spring 10 is movably sleeved on the surface of the T-shaped sliding rod 2. A limit bolt 1 is threadedly installed on the inner cavity of the other end of the T-shaped sliding rod 2. One end of the limit bolt 1 extends to the outside of the fixture body 4. A fixing hole 11 is provided in the middle of the T-shaped sliding rod 2, and a ceramic plug 3 is installed in the inner cavity of the fixing hole 11. The spring force of the spring 10 pushes the T-shaped sliding rod 2 to move, thereby causing the ceramic plug 3 to be inserted into the small hole on the oxygen sensor chip 5. Thus, during the spraying process of the oxygen sensor chip 5, the small hole of the oxygen sensor chip 5 will not be blocked by the sprayed powder. Screw holes 9 are provided on one side of the fixture body 4 and on both sides of the chip fixing slot 8. Two fixing screws 7 are threaded on the fixing block 6, and one end of the fixing screw 7 is threaded into the inner cavity of the screw hole 9 to connect the fixing block 6 to the fixture body 4.

[0015] One end of the spring 10 abuts against the side of the tooling body 4 and one end of the T-shaped sliding rod 2.

[0016] The diameter of the nut at the end of the limiting bolt 1 is larger than the diameter of the through groove 12. The limiting bolt 1 can limit the movement of the T-shaped sliding rod 2 and prevent it from falling out of the inner cavity of the through groove 12. At the same time, the distance by which the limiting bolt 1 is screwed into the inner cavity of the T-shaped sliding rod 2 can be adjusted to adjust the distance by which the T-shaped sliding rod 2 moves to the right.

[0017] The oxygen sensor chip 5 has a small hole, and the ceramic plug 3 passes through the small hole on the oxygen sensor chip 5 and is adapted to the inner diameter of the small hole, so that the small hole can be effectively blocked.

[0018] The tooling body 4 has mounting holes for mounting with bolts on some automated spraying equipment or processing tables.

[0019] In summary, when using this oxygen sensor chip spraying fixture, pulling the limiting bolt 1 to the left moves the T-shaped sliding rod 2, compressing the spring 10 and placing the oxygen sensor chip 5 with a small hole into the chip fixing groove 8 on the side of the fixture body 4. Then, rotating the fixing screw 7 brings the fixing block 6 closer to the fixture body 4, thus fixing the oxygen sensor chip 5 in place. After fixing, slowly loosening the limiting bolt 1 to the right causes the T-shaped sliding rod 2 to move to the right under the action of the spring 10, allowing the ceramic plugging needle 3 to be inserted into the small hole on the oxygen sensor chip 5, thus blocking the small hole and preventing it from being blocked by the sprayed powder during the spraying process. Spraying can then be performed manually or fixed to automated equipment using bolts through the mounting holes on the fixture body 4. Combined with a six-axis robot, automated spraying can be achieved, improving work efficiency.
