Description

Technical Field

[0001] The invention relates to the technical field of sensor manufacturing, and specifically discloses an automatic ring pressing machine for producing temperature sensors. Background Art

[0002] The temperature probe in the temperature sensor is mainly composed of a thermocouple wire and a metal protection tube. During the processing, the metal protection tube is placed on one end of the thermocouple wire, and then a ring pressing machine is used to roll and form a number of concave ring grooves at the end of the metal protection tube (see Appendix Fig.10 ), the formed annular groove realizes a fixed connection between the metal protection tube and the thermocouple wire on the one hand, and seals the inner end of the thermocouple wire on the other hand.

[0003] The working principle of the existing ring pressing machine or rolling machine is to press the pressing wheel directly onto the protective tube through the cylinder, so that the contact part between the protective tube and the pressing wheel is concave inward, and then drive the protective tube to rotate, or drive the pressing wheel to rotate around the central axis of the protective tube, and through the relative rotation between the pressing wheel and the protective tube, an annular groove is rolled on the protective tube.

[0004] Although this type of ring pressing machine or rolling machine can achieve the connection between the thermocouple wire and the metal protection tube in the temperature probe, there are some problems. First, the direct pressing method of the pressing wheel is likely to flatten the end of the metal protection tube, resulting in the metal protection tube being unable to effectively fit with the thermocouple wire; second, when the pressing wheel is directly pressed down, it is easy to damage the thermocouple wire due to excessive pressure, causing the temperature probe to malfunction; third, the resistance of the pressing wheel after direct pressing is large during the relative rotation process with the protection tube, which requires a high power source for the ring pressing machine.

[0005] In addition, when the existing ring pressing machine is in use, the operator inserts the metal protection tubes sleeved on the ends of the thermocouple wires into the inside of the ring pressing machine one by one, which makes it impossible to accurately control the position of the annular groove after forming, resulting in poor product consistency and requiring manual loading and unloading, low operating efficiency and high labor. Therefore, in view of the technical problems existing in the existing ring pressing machine or rolling machine in the process of pressing the temperature probe ring in the temperature sensor, this application proposes an automatic ring pressing machine for temperature sensor production that can effectively solve the above problems. Summary of the invention

[0006] The present invention aims to provide an automatic ring pressing machine for producing temperature sensors, so as to solve the technical problems existing in the existing ring pressing machine or rolling machine during the ring pressing process of the thermocouple wire and the metal protection tube in the temperature probe.

[0007] The present invention is achieved through the following technical solutions: An automatic ring pressing machine for producing temperature sensors, comprising a chassis, a feeding hole is opened on the side of the chassis, a ring body arranged concentrically with the feeding hole and a power assembly driving the ring body to rotate are rotatably arranged in the chassis, one end of the ring body facing the feeding hole is connected with a disc, a plurality of conical surface pressing blocks arranged to move radially are arranged in an annular array on the end surface of the disc, a spring is connected between the conical surface pressing block and the disc, and a pressing wheel is rotatably arranged at the radial inner end of each conical surface pressing block; The outer sleeve of all the conical surface pressure blocks is provided with a conical surface pressure ring, and the inner ring wall of the conical surface pressure ring matches the outer side surface of the conical surface pressure block, and a convex ring extends radially outward on the conical surface pressure ring, and a pushing ring plate is provided on one side of the convex ring, and the end faces of the pushing ring plate and the convex ring close to each other are in friction contact through balls, and a first sliding rod and a screw rod parallel to each other are provided in the chassis, and the end of the screw rod is connected to the ring body through a transmission assembly, and a guide sliding hole acting on the first sliding rod and a screw nut block acting on the screw rod are provided on the pushing ring plate.

[0008] During use of the ring pressing machine disclosed by the invention, the metal protection tube sleeved on the end of the thermocouple wire is fed into the inside of the machine box through the feed hole, so that the tail end of the metal protection tube is located at the position of the pressing wheel.

[0009] Then, the power assembly is started to rotate the ring body. During the rotation of the ring body, the screw rod is rotated synchronously through the transmission assembly. Then, the screw rod and the screw rod nut block are used to push the ring plate toward one side of the conical pressure ring, thereby pushing the conical pressure ring toward one side of the disc. Then, all the conical pressure blocks are synchronously contracted and moved toward the center under the extrusion of the conical pressure ring, thereby gradually pressing the pressure wheel onto the metal protection tube. As the rotation process continues, the indentation of the pressure wheel on the surface of the metal protection tube will gradually deepen. At the same time, the pressure wheel will rotate synchronously with the disc, thereby machining a gradually accelerated rolling ring groove on the surface of the metal protection tube, thereby fixing the connection between the metal protection tube and the thermocouple wire and sealing the inner end of the thermocouple wire.

[0010] Finally, after the ring body rotates a certain number of times, the power assembly is started in reverse to reset the various components inside the chassis. After the reset is completed, the temperature measuring probe processed by the pressure ring can be taken out.

[0011] As a further configuration of the above scheme, a rotating seat is provided in the chassis, the ring body is provided in the rotating seat, the power assembly includes a power motor provided in the chassis, a second gear is provided on the motor shaft of the power motor, and a first gear meshing with the second gear is provided on the ring body.

[0012] As a further configuration of the above scheme, a bearing seat is provided in the chassis, the screw rod is rotatably provided in the bearing seat, the transmission assembly includes a second pulley provided at one end of the screw rod, a first pulley is provided on the ring body, and a transmission belt is provided between the first pulley and the second pulley.

[0013] The above is one of the specific transmission schemes inside the ring pressing machine. The power input of the power motor and the meshing transmission between the gears are used to realize the stable rotation of the ring body and the disc in the rotating seat, and then the power transmission of the transmission belt is used to make the screw rotate synchronously with the disc, so that the roller can rotate and roll the metal protective tube synchronously and the indentation can be deepened simultaneously.

[0014] As a further configuration of the above scheme, the outer side surface of the conical surface pressure block is designed as a conical surface and is provided with a limit strip, and the inner ring wall of the conical surface pressure ring is provided with a limit inclined groove for the limit strip to act on.

[0015] As a further configuration of the above solution, a plurality of balls are evenly arranged circumferentially on the convex ring, and a ball ring groove for interacting with the balls is formed on the end surface of the pushing ring plate.

[0016] Through the above design, the present invention allows the conical pressure block to rotate synchronously with the disc through the action between the limit bar and the limit inclined groove, and reduces the friction resistance between the conical pressure block and the convex ring during rotation through the action of the ball, thereby ensuring the stable operation of the entire internal structure.

[0017] As a further configuration of the above scheme, a plurality of radially arranged first slide rails are arranged in a ring array on the end surface of the disc, each of the conical surface pressure blocks is provided with a slider that acts with the first slide rail, a protruding plate is provided on the disc at the radial outer end of each first slide rail, and the spring is connected between the conical surface pressure block and the protruding plate.

[0018] The design of the spring connection method through the first slide rail can make all the conical pressure blocks stably and synchronously contract and move radially during the rotation of the disc under the extrusion of the conical pressure ring, thereby stably pressing the pressure wheel on the protective metal tube.

[0019] As a further configuration of the above scheme, an automatic loading device is also included, which includes a conveying seat, a conveying belt is arranged in the conveying seat, a plurality of slot blocks are arranged at equal intervals on the conveying belt, and the slot blocks are arranged flush with the feeding hole.

[0020] As a further arrangement of the above scheme, two wheel seats and a first cylinder for pushing the wheel seats to move toward the feed hole are symmetrically arranged on the upper and lower sides of the feed hole, a feeding wheel is rotatably connected to each of the wheel seats, and a feeding motor is connected to the end of the feeding wheel.

[0021] As a further configuration of the above scheme, a distance measuring sensor is arranged on the side of the chassis away from the feed hole, and the distance measuring sensor is aligned with the feed hole.

[0022] The present invention further utilizes the above-mentioned automatic loading device and other designs to utilize a conveyor belt to transport the temperature probe to be processed, and then uses the bite action of the feeding wheel to send it into the chassis for processing. At the same time, the distance measuring sensor can be used to measure the length of the protective metal tube extending into the temperature probe, so that the rolled annular groove is at the set position on the protective metal tube, thereby achieving consistency of all products after processing.

[0023] As a further configuration of the above scheme, a clamping and pulling mechanism is arranged in the chassis between the ranging sensor and the ring body, and the clamping and pulling mechanism includes a moving plate and a second cylinder driving the moving plate to move axially along the ring body, and two clamping plates are symmetrically arranged on the moving plate, and clamping grooves aligned axially with the feed hole are provided on the opposite sides of the two clamping plates, and an opening and closing mechanism is arranged on the moving plate to drive the two clamping plates to move closer to or away from each other.

[0024] The present invention also adopts the design of a clamping and pulling mechanism. After the protective metal tube is automatically extended into the chassis, the existing clamp fixes it and then pulls it inward for a certain distance so that the tail end of the protective metal tube is aligned with the pressing wheel, and then the rolling process is performed. This not only ensures the stability of the protective metal tube during the ring pressing process, but also extends the protective metal tube completely into the chassis so that the ring groove is roll-formed at the tail of the protective metal tube.

[0025] Compared with the prior art, the present invention has the following beneficial effects: When the ring pressing machine disclosed in the present invention processes the protective metal tube in the temperature measuring probe, the design of a series of transmission components inside the chassis can enable the pressing wheel to gradually increase the depth of the indentation during the rotation and rolling process on the protective metal tube, which not only avoids the problem of the thermocouple wire being damaged due to excessive pressure when the pressing wheel is directly pressed down, but also effectively reduces the resistance during the rotation and rolling process, so that the power requirement for the power source of the ring pressing machine is relatively low.

[0026] The protective metal tube in the present invention is subjected to the action of multiple pressure wheels in the circumferential direction at the same time during the pressure wheel rolling process, which can avoid the problem that the metal protective tube is flattened by directly pressing down with a single pressure wheel, resulting in the metal protective tube being unable to fit with the thermocouple wire, thereby improving the pressure ring processing effect of the temperature measuring probe.

[0027] The present invention further provides an automatic loading device, a distance measuring sensor and a clamping and pulling mechanism, which can not only realize fully automatic loading during the pressing ring processing, but also accurately control the position of the temperature measuring probe pressing ring processing, thereby ensuring the consistency of the processed product and improving the product quality.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 10 , and describes the application in detail with reference to embodiments. Example 1

Two to four first slide rails 5 which are arranged radially are provided in an annular array on the left end face of the disc 4, and a protruding plate 401 is fixed on the disc 4 at the radial outer end of the first slide rail 5.

[0033] A slider 6 is provided on the left side of the disc 4 to interact with each first slide rail 5. A conical pressure block 7 is connected to the left end of the slider 6. The outer side of the conical pressure block 7 is designed as a conical surface and a limit strip 701 is provided. A spring 8 is connected between the conical pressure block 7 and the raised plate 401. A plurality of pressure wheel grooves are provided on the radial inner wall of each conical pressure block 7. The specific number of pressure wheel grooves is determined by the number of rolling required by the temperature measuring probe. In this figure, two pressure wheel grooves are provided and are spaced apart along the axial direction of the ring body 3. A pressure wheel 9 is rotatably provided in each pressure wheel groove, and one end of the pressure wheel 9 extends out of the pressure wheel groove by a certain distance.

[0034] A conical pressure ring 10 is sleeved on the periphery of all conical pressure blocks 7. The inner wall of the conical pressure ring 10 matches the outer surface of the conical pressure block 7 and is provided with a limiting inclined groove that acts on the limiting strip 701. A convex ring 11 is radially extended outward from the outer circumferential surface of the conical pressure ring 10, and then a plurality of balls 12 are movably embedded in a circular array on the left side of the convex ring 11. A push ring plate 13 is concentrically arranged on the left side of the conical pressure ring 10, and a ball ring groove 131 that acts on the right side of the push ring plate 13 simultaneously is provided, and then a guide slide hole 132 and a screw nut block 133 are also provided on the push ring plate 13 outside the ball ring groove 131. In the specific design, the screw nut block 133 is arranged at the top of the push ring plate 13, and the two guide slide holes 132 are symmetrically arranged on the front and rear sides of the lower half of the push ring plate 13.

[0035] A bearing seat 14 is fixedly mounted on the top wall of the chassis 1, and a screw 15 is rotatably arranged in the bearing seat 14 to interact with the screw nut block 133. At the same time, two first slide bars 16 that interact with the corresponding guide slide holes 132 are fixedly arranged on the front and rear sides of the lower end of the chassis 1, and the first slide bars 16 and the screw 15 are both arranged horizontally along the axial direction of the ring body 3.

[0036] A first gear 17 and a first pulley 18 are provided on the ring body 3, and then a power motor 19 is fixedly provided in the chassis 1, and a second gear 20 meshing with the first gear 17 is provided on the motor shaft of the power motor 19, so that the ring body 3 can stably rotate in the rotating seat 2 under the meshing transmission of the power motor and the gears. At the same time, a second pulley 21 is provided at the right end of the screw rod 15, and then a transmission belt 22 is provided between the second pulley 21 and the first pulley 18, so that the screw rod 15 can rotate synchronously during the rotation of the ring body 3.

[0037] During use of the automatic ring pressing machine for temperature sensor production disclosed in this embodiment 1, the operator inserts one end of the metal protection tube in the temperature measuring probe into a certain position inside the chassis 1 along the feed hole 101, and then starts the power motor 19, so that the ring body 3, the disc 4 and all the conical pressing blocks 7 rotate synchronously under the meshing transmission of the first gear 17 and the second gear 20.

[0038] During the rotation of the ring body 3, the screw rod 15 is rotated through the transmission action of the first pulley 18, the second pulley 21 and the transmission belt 22, and then the ring plate 13 is pushed to move gradually to the right through the transmission action between the screw rod 15 and the screw nut block 133, and the guiding action between the first slide rod 16 and the guide slide hole 132.

[0039] In the process of pushing the ring plate 13 to move to the right, the conical pressure ring 10 will be forced to move to the right, and due to the action of the ball 12 on the conical pressure ring 10, the conical pressure ring 10 can rotate synchronously with the conical pressure block 7, and will not generate too much friction resistance between the pushing ring plate 13. In the process of the conical pressure block 7 moving to the right, all the conical pressure blocks 7 will be pressed to move synchronously toward the center, so that the pressure wheels 9 on all the conical pressure blocks 7 will press on the metal protection tube from different directions synchronously, and rotate at a high speed relative to the metal protection tube, thereby pressing out a shallow annular groove. As the power motor 19 continues to drive, the pressure wheel 9 will continue to move to the center, so that the rolling depth of the annular groove will gradually deepen, until the set rolling effect is achieved and the power motor 19 stops running.

[0040] Finally, the power motor 19 is driven in reverse to rotate the corresponding number of circles, so that the conical surface pressure block 7, the conical surface pressure ring 10 and the push ring plate 13 are all reset. After the reset is completed, the metal protection tube in the temperature measuring probe is pulled out of the chassis 1 to carry out the pressure ring processing of the next workpiece. Example 2

[0043] A second slide rail 27 is fixed on the left end surface of the chassis 1 above and below the feed hole 101, a wheel seat 28 is slidably arranged in the second slide rail 27, and a first cylinder 29 is arranged on the left end surface of the chassis 1 to push the wheel seat 28 to move toward the feed hole 101. A row of feeding wheels 30 are rotatably connected to each wheel seat 28, and a feeding motor 31 is connected to one end of the feeding wheel 30. When the metal protection tube on the slot block 26 is axially aligned with the feed hole 101, the first cylinder 29 is used to make the two rows of feeding wheels 30 approach each other and bite them, and then the feeding motor 31 drives the feeding wheel 30 to rotate, so that the metal protection tube passes through the feed hole 101 and is sent into the interior of the chassis 1. In addition, a distance measuring sensor 40 is arranged on the right end face of the chassis 1 and is axially aligned with the feed hole 101, and the distance measuring sensor 40 is electrically connected to the control system of the entire ring pressing machine. The distance measuring sensor 40 can detect the length of the metal protective tube fed into the chassis 1 in real time, thereby achieving the effect of accurately controlling the feeding length of the metal protective tube.

[0044] Reference Figure 3 , Attachment Figure 8 and attached Fig. 9 A clamping and pulling mechanism is arranged on the right side of the ring body 3, and the clamping and pulling mechanism includes a moving plate 32 arranged on the rear side of the ring body 3, and a second slide bar 33 is arranged in the chassis 1 to guide the moving plate 32 in the axial direction, and then a second cylinder 34 connected to the moving plate 32 is arranged at the right end of the chassis 1.

Finally, a third cylinder 38 is arranged on the lower surface of the moving plate 32, and the telescopic end of the third cylinder 38 is connected to a notch plate 39, and a guide notch in an eight-shaped shape is opened on the notch plate 39, and the two convex columns 37 act on the two side ends of the guide notch respectively.

[0045] In this embodiment 2, through the cooperation of the above-mentioned automatic feeding device and the clamping and pulling mechanism, the conveyor belt 25 sends the temperature measuring probe to be aligned with the feed hole 101, and then the two first cylinders 29 are started synchronously to make the upper and lower wheel seats 28 approach each other, so that the temperature measuring probe is clamped by the upper and lower rows of feeding wheels 30.

[0046] Next, the feeding motor 31 is started to drive the feeding wheel 30 to rotate, and the metal protection tube on the temperature measuring probe is fed into the inside of the chassis 1 through the feeding hole 101, and the distance sensor 40 detects the length of the metal protection tube extending into the chassis 1 in real time. When the set position is reached, the third cylinder 308 is started. During the movement of the notch plate 39, the two clamping plates 36 are brought closer to each other through the action of the guide notch and the protruding column 37, thereby clamping the end of the metal protection tube. After clamping, the second cylinder 34 is started to pull it back a certain distance, so that the position of the metal protection tube to be rolled is between the conical surface pressing blocks 7.

[0047] Then, the power motor 19 is started to perform a gradually deepening rotational pressing ring processing on the metal protection tube. After the processing is completed, the power motor 19 is controlled to rotate in the reverse direction and reset, and then the automatic loading device and the clamping and pulling mechanism are started in the reverse direction to put the processed temperature measuring probe back into the slot block 26. Finally, the processed workpiece is sent away by the conveyor belt 25, and the new workpiece to be processed is sent to the position aligned with the feed hole 101 and the above actions can be repeated.
