Description

Technical Field

[0001] The invention relates to the field of heating and ventilation, and in particular to a temperature control component distance measurement and calibration machine. Background Art

[0002] The temperature control component consists of a bellows filled with a special temperature-sensitive liquid. The balance between the temperature-sensitive liquid and the saturated gas enables the controller to perform proportional adjustment according to the air temperature. It pushes and contracts the valve stem as the temperature changes. When the indoor temperature rises, part of the temperature-sensitive liquid inside the bellows is converted into gas, causing the bellows to expand and push the valve stem to close the valve; when the indoor temperature drops, the bellows contracts under the tension of the spring, and the valve stem opens the valve upward. Under normal circumstances, temperature control components can only be manufactured and produced when the ambient temperature is 20 degrees. If the ambient temperature is not constant, the bellows will not be fixed. Therefore, the following defects exist in the existing production and manufacturing of temperature control components:

[0003] 1. Because the ambient temperature is not constant, and the bellows of the temperature bulb is not fixed under non-constant temperature, it is impossible to accurately mass-produce the thermostatic heads in the existing manufacturing process. During assembly, the height from the reference surface to the ejector pin must be 12 mm at an ambient temperature of 20 degrees to maintain consistency with the closing height of the valve body. Therefore, unstable room temperature will lead to deviations in the production results of the thermostatic heads and make mass production impossible, which will reduce production efficiency and increase the price of each product, thereby reducing production technical requirements and production quantity.

[0004] 2. In the production of temperature control components, since the temperature control head is connected to the base film and a pick-and-place process is required for each production, in the existing technology, manual placement and removal of the equipment before and after processing requires accurate estimation of the position of the temperature control head, which consumes a lot of manpower and time. In addition, manual placement reduces the degree of automation of the equipment and significantly reduces the overall production efficiency of the device.

[0005] Therefore, the present invention proposes a temperature control component distance measurement and calibration machine to make up for and improve the shortcomings of the existing technology. Summary of the Invention

[0012] Preferably, the five-kilogram weight is fixedly connected to the No. 2 cylinder, the ranging rod is fixedly connected to the five-kilogram weight, and the ranging rod moves vertically following the five-kilogram weight.

[0013] The top end of the fixing plate is connected to the fixing plate by rotating the fixing plate, and the bottom end of the fixing plate is connected to the fixing plate by rotating the fixing plate. The wheelbase is shortened and the shifting is accelerated to rotate with the speed of the hoisting gear, and the reduction gear rotation is gradually increased with the increase in the speed of the rotation of the wheel shaft and the reduction gear rotation.

[0014] Preferably, two push plates and two bottom membranes are symmetrically arranged, the acute-angle rod is slidingly connected to the eccentric circular groove, a cylindrical block is provided at the bottom end of the slide rod, and a vertical groove is opened on the right side of the rear end of the push plate, which is slidingly connected to the cylindrical block at the bottom end of the slide rod.

[0015] Preferably, a slide rail slidably connected to the T-shaped slider is provided on the right side of the fixed plate, so that the T-shaped slider can only move vertically relative to the fixed plate.

[0016] Preferably, a thrust cylinder is provided at the bottom of the push plate, which can push the push plate to move left and right as a whole.

[0017] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects:

[0018] 1. The present invention utilizes a push plate at one end to move left and right, which will drive the connecting blocks at both ends to move closer or farther away synchronously, driving the circular rotating plate and the fixed-axis gear to rotate, thereby driving the pushing plate to rise, pick up and place the temperature control head. When the push plates on both sides move away from each other, the pushing plate will be driven to follow the T-shaped slider to move upward first to lift the processed temperature control head, and then follow the left and right swing of the slide bar to move forward, and send the lifted temperature control head to the front. After retrieval, due to the reciprocating motion of the circular rotating plate, the workpiece to be processed is placed, and the pushing plate will follow the rotation of the circular rotating plate to return to its initial position. According to the automatic lifting and placement of the temperature control head by the pushing plate, the temperature control head is driven to be picked up and installed through the reciprocating motion, which eliminates the time consumed in manual installation of the temperature control head, increases the production rate of the temperature control head, and greatly improves its production continuity.

[0019] 2. The present invention utilizes that when the probe body is rotated, the ranging rod is always in the actual height during detection. When it reaches a size of 12 mm, the equipment automatically stops. At this time, the temperature control head is removed, so that the probe body can be adjusted so that the ambient temperature is 20 degrees. By rotating the probe body multiple times, the temperature is continuously changed while the height difference between the probe body and the top rod is fixed at 12 mm. Each time the probe body rotates, the height difference between the probe body and the top rod is recorded in the PLC. The accuracy of the measurement result can be judged by observing whether it is stable.

[0020] 3. The present invention utilizes the vertical movement of cylinder No. 1 to drive the servo motor, ranging rod and transmission belt to move, which can ensure product accuracy and automation during batch inspection and production of temperature control heads. By controlling the movement of cylinder No. 1 and cylinder No. 2 to drive the entire device to move and detect, the overall device is free from excessive human factors that affect its product quality, thereby improving the automation efficiency of the equipment.

[0021] 4. When the horizontal push rod 1 is used for horizontal movement, the present invention will drive the connecting rod 2 and the connecting rod 3 to rotate synchronously. Since the lower ends of the connecting rod 2 and the connecting rod 3 are both rotatably connected to the telescopic rod, and since the right end of the horizontal push rod 2 is fixedly connected to the connecting block, when the push plate at one end moves left and right, it will drive the connecting blocks at both ends to move synchronously closer or farther away. The synchronous movement of the connecting blocks can make the bottom film synchronously clamp and release the temperature control head, and can achieve synchronous coordinated movement with the push plate to improve the overall automatic coordination of the equipment.

[0051] refer to Figures 9 to 11 When the cam 314 is in the unlocking state, the gear 312 is locked and the locking cam 316 is locked, so the cam 316 can be locked to the unlocking state, and the locking cam 316 can be locked to the unlocking state.

[0052] Summary 2: According to the automatic lifting and placement of the temperature control component 29 by the push plate 38, the temperature control head 29 is driven to be picked up and installed through reciprocating motion, which eliminates the time spent on manual installation of the temperature control head 29, increases the production rate of the temperature control head 29, greatly improves its production efficiency, and makes the overall equipment highly automated.

[0053] The complete working principle and steps of the above embodiment are as follows:

[0054] Initial limit: When the device is in the initial state, Figure 2 As shown, the two push plates 31 symmetrically arranged on the left and right are now in contact with each other, so that the bottom films 210 arranged on the left and right are in contact with the outer wall of the temperature control head 29. At this time, the No. 1 cylinder 22 and the No. 2 cylinder 23 are in the extended state. Figure 4 As shown, at this time, the top end of the push plate 38 is lower than the bottom end of the temperature control head 29, and the distance between the top end of the push plate 38 and the bottom end of the temperature control head 29 is at the maximum stroke;

[0055] When using:

[0056] Steps for fixing the height difference at constant temperature:

[0057] First, since the bellows height of the temperature bag body 214 needs to be unified, it is necessary to work in a constant temperature environment, the temperature of the working environment is fixed at 20 degrees, and the temperature control head 29 is placed at room temperature of 20 degrees for more than one hour. Since the natural environment temperature is constantly changing and the bellows height of the temperature bag body 214 is artificially high, it is necessary to set a height difference of twelve millimeters at the bottom of the five-kilogram weight 21, fix the temperature bag jacket 215 on the outside of the temperature bag body 214, detect the height of the probe body 212 at this time, and make the top rod 213 bear the weight of the five-kilogram weight 21 and detect its height at this time, record the height difference between the probe body 212 and the top rod 213 in the PLC, rotate the probe body 212 to make the top rod 213 rotate relative to the probe body 212, thereby changing the probe The height difference between the probe body 212 and the push rod 213 is measured, and the rotation is stopped when the height difference between the probe body 212 and the push rod 213 is twelve millimeters. When the probe body 212 is rotated, the ranging rod 25 is always at the actual height when detecting. Until it reaches a size of twelve millimeters, the PLC controls the No. 2 cylinder 22 to stop moving and the equipment automatically stops. At this time, the temperature control head 29 is taken out, so that the probe body 212 can be adjusted so that the ambient temperature is twenty degrees. By rotating the probe body 212 multiple times, the temperature is constantly changed while ensuring that the height difference between the probe body 212 and the push rod 213 is fixed at twelve millimeters. Each time the probe body 212 rotates, the height difference between the probe body 212 and the push rod 213 will be recorded in the PLC. The accuracy of the measurement result can be observed by observing whether it is stable.

[0058] Automatic control steps for detection accuracy:

[0059] First, the five-kilogram weight 21 is set on the top of the reference frame 12, and its vertical movement is controlled by the second cylinder 23. Since the distance measuring rod 25 is fixedly connected to the five-kilogram weight 21, the distance measuring rod 25 will move downward under the gravity of the five-kilogram weight 21 and detect the top rod 213 inside the temperature control head 29. When the five-kilogram weight 21 drops to a certain height due to gravity, the second micrometer 26 records the height of the five-kilogram weight 21 after it drops. Since the first cylinder 22 is connected to the servo The motor 24, the distance measuring rod 25, the transmission belt 27 and the rotating adjustment rod 28 are connected, so under the action of the No. 1 cylinder 22, it moves downward as a whole until the straight rod at the lower end of the rotating adjustment rod 28 is stuck in the groove inside the temperature control head 29. Since the No. 3 cylinder 216 is fixedly connected to the reference frame 12, when the equipment is started, the No. 3 cylinder 216 descends until the reference frame 12 is close to the plane of the upper end of the temperature control head 29. At the same time, the No. 1 micrometer 211 records the size height of the No. 3 cylinder 216 after movement. At this time, the servo motor 24 is connected to the rotating adjustment rod 28 through the transmission belt 27, and the rotating probe body 212 can make the temperature bag jacket 215 fit the inner wall of the temperature control head 29. Therefore, when the temperature control head 29 to be calibrated is placed in the bottom mold bottom film 210, the equipment is started, and the No. 1 cylinder 22 drives the rotating adjustment rod 28 to drop until the straight rod is stuck in the probe body 212. At this time, the five-kilogram weight 21 drives the ranging rod 25 to naturally fall on the plane of the push rod 213 under the action of gravity. At this time, the No. 2 cylinder 23 The vertical movement drives the five-kilogram weight 21 and the distance measuring rod 25 to move. The vertical movement of the No. 1 cylinder 22 drives the servo motor 24, the distance measuring rod 25 and the transmission belt 27 to move, which can ensure product accuracy and automation during batch inspection and production of the temperature control head 29. By controlling the movement of the No. 1 cylinder 22 and the No. 2 cylinder 23, the entire device is driven to move and detect, so that the overall device will not have too many human factors affecting its product quality, thereby improving the automation efficiency of the equipment and high-quality production efficiency.

[0060] Automatically remove the temperature control head 29 steps:

[0061] Depend on Figure 4When the cam 33 is in the upright position, the cam 33 is in the upright position, and the cam 33 is in the upright position, so that the cam 33 is in the upright position, and the cam 33 is in the upright position, so that the cam 33 is in the upright position, and the cam 33 is in the upright position, so that the cam 33 is in the upright position, so that the cam 33 is in the upright position, so that the cam 33 is in the upright position, so that the cam 33 is in the upright position, so that the cam 33 is in the upright position, so that the cam 33 is in the upright position, so that the cam 33 is in the upright position, so that the cam 33 is in the upright position, The vertical groove on the right side of the rear end of the plate 38 is slidably connected to the cylindrical block at the bottom end of the slide rod 36, so the pushing plate 38 can follow the swing of the acute angle rod 35 to move left and right, and the pushing plate 38 can follow the up and down movement of the T-shaped slider 37 to move up and down. Since the irregular sliding groove 39 is provided on the left side of the circular rotating plate 33, the right rear end of the fixed plate 32 is rotatably connected to the irregular rotating plate 310, and the irregular rotating plate 310 is slidably connected to the irregular sliding groove 39, and the irregular rotating plate 310 is slidably connected to the T-shaped slider 37. Therefore, when the irregular rotating plate 310 rotates, the end thereof slidably connected to the T-shaped slider 37 will slide relative to the T-shaped slider 37. Since the up and down distance between them changes, the T-shaped slider 37 will move up and down at this time. In addition, since the irregular rotating plate 310 is slidably connected to the inner wall of the T-shaped slider 37, the rotation of the circular rotating plate 33 can drive the irregular rotating plate 310 to swing, thereby driving the T-shaped slider 37 to move up and down;

[0062] Depend on Figure 9 and Figure 11As shown, since the rear side of the fixed plate 32 is rotatably connected to the fixed axis gear 311 that coincides with the rotation center of the circular rotating plate 33, and the rear side of the fixed axis gear 311 is meshedly connected to the rack 312, and since the upper end of the rack 312 is rotatably connected to the connecting rod 1 313, and the end of the connecting rod 1 313 away from the rack 312 is rotatably connected to the connecting block 314, the rotation of the fixed axis gear 311 will drive the rack 312 to move up and down, thereby driving the connecting rod 1 313 to rotate, and then the connecting block 314 will follow the connecting rod 1 313 to move horizontally. There are two and fixedly connected to the bottom surface of the push plate 31, and the right side of the connecting block 314 is fixedly connected to the horizontal push rod 1 315, and because the end of the horizontal push rod 1 315 away from the connecting block 314 is rotatably connected to the connecting rod 2 316, and the middle part of the connecting rod 2 316 is rotatably connected to the connecting rod 3 317, and the upper end of the connecting rod 317 is rotatably connected to the horizontal push rod 2 319, so when the horizontal push rod 1 315 performs horizontal movement, it will drive the connecting rod 2 316 and the connecting rod 3 317 to rotate synchronously. Since the lower ends of the connecting rod 2 316 and the connecting rod 3 317 are connected to the telescopic rod 318 The rotation connection, and since the right end of the horizontal push rod 319 is fixedly connected to the connecting block 314, when the push plate 31 at one end moves left and right, it will drive the connecting blocks 314 at both ends to move synchronously close or away. Therefore, the pushing replacement mechanism 3 will drive the circular rotating plate 33 and the fixed axis gear 311 to rotate through the movement of the push plate 31, thereby driving the pushing plate 38 to rise and pick up and place the temperature control head 29. When the push plates 31 on both sides are away from each other, the pushing plate 38 will be driven to follow the T-shaped slider 37 to move upward first to support the processed temperature control head 29 The push plate 38 is lifted up and then moves forward following the left and right swing of the slide bar 36 to send the lifted temperature control head 29 to the front. After retrieving it, the circular turntable 33 is in reciprocating motion to place the workpiece to be processed. The push plate 38 will follow the rotation of the circular turntable 33 to return to the initial position. According to the automatic lifting and placement of the temperature control head 29 by the push plate 38, the temperature control head 29 is driven to be picked up and installed through the reciprocating motion, which eliminates the time spent on manual installation of the temperature control head 29, increases the production rate of the temperature control head 29, greatly improves its production efficiency, and makes the equipment as a whole highly automated.
