Description

Technical Field

[0001] This utility model relates to the field of temperature sensor manufacturing technology, and in particular to a tooling for processing the metal housing port of a temperature sensor. Background Technology

[0002] A temperature transducer is a sensor that senses temperature and converts it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments and come in a wide variety of types. They can be broadly classified into two categories based on their measurement method: contact and non-contact. Based on the characteristics of their sensor materials and electronic components, they are further divided into resistance temperature detectors (RTDs) and thermocouples.

[0003] After the metal housing of the temperature sensor is manufactured, its ends need to be polished and deburred. The conventional deburring operation is usually carried out by manually holding the metal housing close to the polishing disc of the polishing machine. Under long-term operation, the workers are prone to fatigue, which can easily lead to operational errors, accidental injury, and affect normal production and processing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a tooling for processing the metal housing port of a temperature sensor, thereby solving the problems mentioned in the background section.

[0005] A metal housing port processing fixture for a temperature sensor includes a base and a drive mechanism and a grinding machine mounted on the base. The drive mechanism includes a drive assembly and a limiting part. The drive assembly includes a gear ring, a drive part, a push assembly, and a rotating seat. The rotating seat is rotatably mounted on the base. The gear ring is fixedly mounted on the lower end of the rotating seat. The drive part is mounted on the side wall of the base for driving the gear ring to rotate. The push assembly is fixedly mounted on the base and is set to correspond to the running trajectory of the limiting groove.

[0006] The limiting part is configured in multiple sets, each corresponding to the limiting groove of the rotating seat. The limiting part includes a limiting block, a first spring, a push rod, and a second spring. Each set of limiting blocks consists of two blocks that are slidably positioned on both sides of the limiting groove and are fixedly connected to the rotating seat by the first spring. The push rod and the second spring are inserted into the limiting groove, with the push rod passing through the second spring.

[0007] By adopting the above technical solution, the device does not require workers to hold the metal casing and grind its end with a grinder, which is more labor-saving and reduces the possibility of operator errors due to prolonged operation.

[0008] The two limiting blocks in the same group have an arc-shaped structure at their closest ends, and their upper surfaces are provided with inclined surfaces.

[0009] The above technical solution facilitates the clamping of the metal casing.

[0010] The push rod includes a straight rod and a support platform. The upper surface of the support platform is recessed, and its diameter is adapted to the diameter of the limiting groove. The length of the straight rod is greater than the length of the limiting groove.

[0011] By adopting the above technical solution, the metal casing can be moved upwards for polishing.

[0012] The grinder is mounted on the base via a bracket, and the grinder and the pushing component are arranged vertically in correspondence.

[0013] By adopting the above technical solution, the metal shell is pushed upward, and the metal shell is polished by a grinding machine.

[0014] Each of the aforementioned limiting parts is arranged centripetally toward the central axis of the rotating seat.

[0015] By adopting the above technical solution, the metal shell is evenly distributed and clamped.

[0016] The beneficial effects of the metal housing port processing fixture of this utility model temperature sensor are:

[0017] The drive unit rotates the gear ring, which in turn rotates the rotating seat on the base until a metal shell on the rotating seat moves directly below the grinder. At this point, the drive component pushes a corresponding push rod above it upwards, which in turn pushes the metal shell upwards. The grinder then grinds the end of the metal shell. This device eliminates the need for operators to hold the metal shell and grind its end through the grinder, saving effort and reducing the risk of operator errors due to prolonged operation.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0023] Reference Figs. 1-3 A metal housing port processing fixture for a temperature sensor includes a base 1 and a drive mechanism and a polishing machine 5 mounted on the base 1. The drive mechanism includes a drive assembly and a limiting part 8. The drive assembly includes a gear ring 2, a drive part 3, a push assembly 6, and a rotating seat 7. The rotating seat 7 is rotatably mounted on the base 1. The gear ring 2 is fixedly mounted on the lower end of the rotating seat 7. The drive part 3 is mounted on the side wall of the base 1 for driving the gear ring 2 to rotate. The push assembly 6 is fixedly mounted on the base 1 and is set to correspond to the running trajectory of the limiting groove 701.

[0024] The limiting part 8 is provided in multiple sets, each corresponding to the limiting groove 701 of the rotating seat 7. The limiting part 8 includes a limiting block 801, a first spring 802, a push rod 803 and a second spring 804. Each set of limiting blocks 801 consists of two blocks that are slidably disposed on both sides of the limiting groove 701 and are fixedly connected to the rotating seat 7 by the first spring 802. The push rod 803 and the second spring 804 are inserted into the limiting groove 701, and the push rod 803 passes through the second spring 804.

[0025] According to the length of the metal shell, a spring of appropriate length can be placed in the limiting groove 701. Then, the push rod 803 is inserted into the limiting groove 701, extending downward to the bottom of the rotating seat 7 and through the push rod 803.

[0026] The metal casing can then be inserted into the limiting groove 701. The two limiting blocks 801 in the same group have an arc-shaped structure at their closest ends, and their upper surfaces are inclined. Each limiting part 8 is oriented towards the central axis of the rotating seat 7. When the metal casing is placed, the bottom of the metal casing will press downwards to push open the two limiting blocks 801 in the same group. After the bottom of the metal casing is placed on the top of the push rod 803, the limiting blocks 801, through the elastic force provided by the spring 802, clamp and limit the metal casing. (The end of the limiting block 801 that contacts the metal casing has an arc-shaped structure, ensuring stable clamping of the metal casing as much as possible.)

[0027] The push rod 803 includes a straight rod and a support. The upper surface of the support is recessed, and its diameter is adapted to the diameter of the limiting groove 701. The length of the straight rod is greater than the length of the limiting groove 701. The push rod 803 can be pushed upward so that the support at its top protrudes from the limiting groove 701, making it easy to remove the push rod 803 from the limiting groove 701. The spring can be hooked out using an external hook or other object.

[0028] Then, the grinder 5 can be driven, and the drive unit 3 (which includes a motor and gears) can be driven. The motor of the drive unit 3 drives the gear ring 2 to rotate through the gear at its output end. The gear ring 2 can drive the rotating seat 7 to rotate on the base 1 until a metal shell on the rotating seat 7 moves directly below the grinder 5. At this time, the push assembly 6 (which includes an electric cylinder and a support plate) can be driven. The electric cylinder of the push assembly 6 can push the support plate at its output end to push a corresponding push rod 803 above it to move upward, thereby pushing the metal shell to move upward. The grinder 5 includes a motor and a grinding disc. The motor of the drive unit 3 drives the grinding disc at its output end to grind the end of the metal shell.

[0029] The device eliminates the need for staff to hold the metal casing and grind its end with a grinder 5, saving effort and reducing the likelihood of operator errors due to prolonged operation.

[0030] The grinder 5 is mounted on the base 1 via the bracket 4, and the grinder 5 and the push component 6 are arranged vertically in correspondence. After the metal shell moves to directly below the grinder 5, the push component 6 can be driven to push the metal shell upward and contact the grinding disc of the grinder 5 to perform grinding and deburring.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
