Description

Technical Field

[0001] The utility model relates to the technical field of temperature transmitter processing, in particular to a production tool for a temperature transmitter. Background Art

[0002] The temperature transmitter is an instrument that converts temperature variables into a transmittable standardized output signal. The temperature transmitter has a slender probe rod 100 , the interior of which is filled with thermal sand and sealed with glue.

[0003] At present, the production process of temperature probes is relatively simple, and artificial hot sand is generally used, such as Figures 1 to 2 As shown, production staff use a spoon to pour thermal sand into the probe rod 100 through a tool such as a funnel 101 until the top of the probe rod 100 is flush. The poured product is manually vibrated up and down on a wooden board 102 10-20 times to compact the thermal sand. The vibrated product is then placed in an incubator for heating to remove moisture from the thermal sand. The heated product is then quickly taken out for sealing with glue.

[0004] Based on the existing production process of temperature transmitters, the production environment of manual vibration is relatively harsh (mainly dust and high temperature). At the same time, the production quality is basically determined by the experience level of the production staff. That is, after the staff completes the pouring, they perform manual vibration. The density of the thermal sand obtained after vibration cannot be controlled. The inconsistent density of the thermal sand will affect the measurement accuracy of the temperature transmitter product. Utility Model Content

DETAILED DESCRIPTION

[0030] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0031] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Reference Figures 3 to 8 As shown, an embodiment of the present invention provides a production tool for a temperature transmitter, which mainly includes a first carrier 2, a second carrier 3, a vibration source 4 and a bracket 5, and the second carrier 3 is movably supported on the bracket 5.

[0033] The first carrier 2 has a clamping portion for clamping the temperature transmitter probe 1 and making it vertically arranged; in some practical applications, refer to Figures 5 and 6As shown, the clamping portion includes a through-hole 22 extending through the first carrier 2 and having at least three blind holes uniformly formed in the radial direction on its sidewall. A clamping ball 23 is disposed within the blind hole and is movable within the blind hole without falling out of the blind hole. A clamping spring (not shown) is disposed within the blind hole, with its ends respectively abutting the bottom of the blind hole and the clamping ball 23. The clamping ball 23 can be switched between a first position and a second position under the action of the clamping spring. In the first position, the clamping ball 23 is retracted into the blind hole; in the second position, the clamping ball 23 at least partially extends outside the open end of the blind hole. The clamping portion can be described with reference to the principle of an elastic ball bushing in the prior art. The temperature transmitter probe 1 passes through the through-hole 22 to achieve radial positioning of the temperature transmitter probe 1. A plurality of clamping steel balls 23 can elastically compress the temperature transmitter probe 1 to achieve clamping and positioning of the temperature transmitter probe 1, thereby preventing the temperature transmitter probe 1 from sliding relative to the through-hole 22 during vibration of the vibration source 4. The temperature transmitter's stopper 11 (i.e., the protruding portion above the probe 1, which is generally annular in shape) abuts against the first carrier 2 to achieve axial positioning of the temperature transmitter.

[0034] In some practical applications, reference Figure 5 and Figure 6 As shown, a slot 24 is further provided on the first carrier 2 at a position corresponding to the clamping portion. The limiting portion 11 of the temperature transmitter at least partially abuts against the slot 24 to achieve radial limitation. Specifically, the shape of the slot 24 can be configured as a semi-arc shape and is adapted to the diameter of the limiting portion 11. After the temperature transmitter probe 1 is positioned, the slot 24 radially limits the limiting portion 11, thereby ensuring, to a certain extent, the stability of the temperature transmitter probe 1 during vibration.

[0035] The clamping portion can position the temperature transmitter probe 1 vertically, ensuring the accuracy of the sand filling operation. When filling the temperature transmitter probe 1 with thermal conductive sand, vertical positioning allows the thermal conductive sand to enter the temperature transmitter probe 1 smoothly and accurately, avoiding uneven or incomplete filling caused by tilting and other reasons, and improving the consistency of product quality.

[0036] The second carrier 3 is located below the first carrier 2 and is connected to the first carrier 2; a vibration source 4 (in some practical applications, the vibration source 4 is a vibration motor) is installed on the second carrier 3 to drive the second carrier 3 to vibrate, thereby driving the first carrier 2 and the temperature transmitter probe 1 clamped on the first carrier 2 to vibrate. The provision of the vibration source 4 helps to better fill the interior of the temperature transmitter probe 1 with thermal conductive sand during the sand filling process. Vibration can make the sand grains tighter and improve the density and uniformity of the filling. In some practical applications, the connection method between the second carrier 3 and the first carrier 2 can be an elastic connection or a rigid connection, so that when the vibration source 4 vibrates, it can transmit the vibration force to the first carrier 2 through the second carrier 3, thereby helping the temperature transmitter probe 1 on the first carrier 2 to maintain a certain frequency of vibration, so as to achieve the effect of compacting the thermal conductive sand inside it.

[0037] In other practical applications, considering that bubbles may exist in the glue during the glue filling operation, which may reduce the sealing effect, the provision of the vibration source 4 can also help to remove bubbles in the glue during the glue filling process, thereby improving the sealing performance of the glue.

[0038] To sum up, a vibration source 4 is arranged on the second carrier 3, which can transmit the vibration force to the first carrier 2 through the second carrier 3, thereby driving the temperature transmitter probe 1 clamped on the first carrier 2 to vibrate. When the temperature transmitter probe 1 is filled with thermal sand, the density and uniformity of the sand particles are ensured. Compared with manual vibration compaction operations, the consistency of the product is better, and the measurement accuracy of the product is guaranteed.

[0039] In some practical applications, refer to Figures 4 to 7 As shown, a stopper is provided on the second carrier 3, corresponding to the position of the clamping portion, to engage with the temperature transmitter probe 1. The clamping portion and the corresponding stopper cooperate to form a clamping assembly. Specifically, the stopper is a positioning hole 32 adapted to the outer diameter of the temperature transmitter probe 1. The clamping portion and the positioning hole 32 simultaneously position the temperature transmitter probe 1, with both located at the upper and lower ends of the temperature transmitter probe 1. This ensures the verticality of the overall structure of the temperature transmitter probe 1, and to a certain extent, ensures the consistency of the thermal sand filling in the subsequent process.

[0040] In other practical applications, refer to Figure 4As shown, the production tooling includes multiple clamping assemblies, each comprising a plurality of clamping parts disposed on the first carrier 2 and a plurality of position limiting parts disposed on the second carrier 3, corresponding one to each of the clamping parts. This allows the production tooling to form several processing stations. This multi-station design allows for simultaneous operation of multiple temperature transmitter probes 1, improving production efficiency. While one station is performing operations such as glue or sand filling, other stations can simultaneously perform clamping or preparatory work, reducing waiting time during the production process.

[0041] In some practical applications, refer to Figure 4 and Figure 8 As shown, based on the fact that the production tooling has multiple processing stations, it also includes a drive mechanism 6, which is connected to the first carrier 2 and / or the second carrier 3 to drive the first carrier 2 and / or the second carrier 3 to move. Specifically, the drive mechanism 6 includes a shaft 61, a gear 62, and meshing teeth 63. The input end of the shaft 61 is connected to an external drive source; the gear 62 is coaxially arranged on the shaft 61; the meshing teeth 63 are arranged on the first carrier 2 and / or the second carrier 3 and mesh with the gear 62.

[0042] Specifically, if Figure 8 As shown, the second carrier 3 is movably arranged on the bracket 5 (the second carrier 3 can rotate and vibrate relative to the bracket 5), and the gear 62 is also configured with two groups, which are respectively engaged with the meshing teeth 63 on the first carrier 2 and the second carrier 3; in this embodiment, the first carrier 2 and the second carrier 3 are basically circular, and the inner ring is provided with a gear ring to form the meshing teeth 63, and the two gears 62 are respectively engaged with the two gear rings. Compared with the engagement of a single gear 62 and the meshing teeth 63, this arrangement can further improve the transmission accuracy and stability.

[0043] In this embodiment, the rotation of the shaft 61 drives the first and second platforms 2 and 3 to rotate about the central axis of the ring formed by the clamping portions, facilitating switching between workstations. Between different operating steps, the temperature transmitter probe 1 can be quickly moved to the corresponding mechanism, such as from the sand filling station to the glue filling station, improving the continuity of the production process and the automation level of the production tooling.

[0044] In some practical applications, refer to Figure 3As shown, the production tooling also includes a sand filling mechanism 7 and a glue filling mechanism 8. The sand filling mechanism 7 has a sand filling port 71 for filling thermal conductive sand into the temperature transmitter probe 1; the glue filling mechanism 8 has a glue filling port 81 for filling glue into the temperature transmitter probe 1 after it has been filled with thermal conductive sand. When the sand filling port 71 is aligned with the opening of the temperature transmitter probe 1 on one clamping part, the glue filling port 81 is aligned with the opening of the temperature transmitter probe 1 on the other clamping part.

[0045] The sand-filling mechanism 7 and the glue-filling mechanism 8 are both relatively mature existing technologies that can perform quantitative sand and glue filling. They will not be described in detail here. The sand-filling mechanism 7 and the glue-filling mechanism 8 are integrated into the production tooling and correspond to the openings of the temperature transmitter probe 1 on two different clamping parts of the production tooling, respectively, realizing the integration of sand-filling and glue-filling operations. Operators only need to clamp and operate the temperature transmitter probe 1 on the tooling, without having to transfer the temperature transmitter probe 1 between different equipment, which improves production efficiency and operational convenience. At the same time, the integrated design also helps to ensure the relative position accuracy of the sand-filling and glue-filling operations, improving the stability of product quality.

[0046] In some practical applications, based on the above-mentioned connection method between the first carrier 2 and the second carrier 3, an elastic connection is adopted in this embodiment, that is, an elastic member 33 is provided between the first carrier 2 and the second carrier 3 to elastically connect the first carrier 2 and the second carrier 3.

[0047] Specifically, refer to Figure 4 、 Figure 5 and Figure 7 As shown, the upper end surface of the second carrier 3 is provided with at least one guide rod 31. The lower end surface of the first carrier 2 is provided with an insertion hole 21 corresponding to the guide rod 31. The free end of the guide rod 31 is movably inserted into the insertion hole 21, so that the first carrier 2 has a certain amount of space to move on the top of the guide rod 31, that is, it can slide up and down. The elastic member 33 (usually a spring) is mounted on the outside of the guide rod 31.

[0048] In this embodiment, when the vibration source 4 causes the second carrier 3 to vibrate, the vibration force is transmitted to the plurality of elastic members 33 through the second carrier 3, causing the elastic members 33 to push the first carrier 2 above it to continuously rock up and down, making the sand particles more compact and improving the density and uniformity of the filling. The guide rods 31 are provided to guide the rocking direction of the first carrier 2. It is important to note that in actual operation, the vibration frequency of the vibration source 4 and the depth of the plurality of sockets 21 need to be adjusted to ensure that the thermal sand is vibrated with appropriate force, while also preventing excessive vibration force from causing the first carrier 2 to dislocate from the plurality of guide rods 31.

[0049] In other practical applications, a constant temperature warehouse 9 (such as Figure 3 ), the design of the constant temperature chamber 9 can preheat the thermal sand and the temperature transmitter probe 1 at the same time to eliminate water vapor, and cooperate with the fully automatic glue filling process and thermal sand filling process to avoid scalding accidents of the staff.

[0050] like Figure 3 As shown in some practical applications, the specific working process of the production tooling of the temperature transmitter is as follows: a temperature transmitter probe 1 is placed on each of the eight clamping parts (uniformly distributed in a ring shape) of the first carrier 2, so that the clamping parts clamp the temperature transmitter probe 1, and at the same time, the lower end of the temperature transmitter probe 1 extends into the positioning hole 32; the driving mechanism 6 works so that the open end of one of the temperature transmitter probes 1 is facing the sand filling port 71, and the sand filling mechanism 7 is opened to complete the filling operation of the thermal sand, and this is repeated until eight temperature probes 1 are fixed. The transmitter probe rods 1 are all filled with thermal sand; the vibration source 4 is controlled to work, driving the second carrier 3 to vibrate, and then driving the first carrier 2 and the temperature transmitter probe rod 1 clamped on the first carrier 2 to vibrate, so that the sand particles in the temperature transmitter probe rod 1 are more compact, and the filling density and uniformity are improved; finally, the driving mechanism 6 is operated to make the open end of one of the temperature transmitter probe rods 1 face the glue filling port 81, and the glue filling mechanism 8 is opened to complete the glue filling, and this is repeated until all eight temperature transmitter probe rods 1 are filled with glue.

[0051] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
