Description

Technical Field

[0001] This utility model relates to the field of shoe manufacturing equipment technology, and in particular to a shoe machine pressure calibration device. Background Technology

[0002] The shoe machine pressure calibration device is a key tool used to calibrate and test pressure parameters in footwear manufacturing equipment. It is usually mounted on the shoe press machine to facilitate engineers in adjusting the pressure parameters.

[0003] With the development of production technology, newly manufactured shoe presses come with a matching pressure calibration device. However, for older shoe presses, without the testing of a pressure calibration device, engineers can only adjust the pressure parameters based on their own experience. This can easily lead to deviations during the shoe pressing process, resulting in defective products. Therefore, a separate pressure calibration device has been developed. However, it can only be assembled after installing studs or drilling holes on the shoe press. Not only is it difficult to adjust the position of the pressure calibration device, but it is also difficult to disassemble it after adjusting the pressure parameters, resulting in low practicality. Utility Model Content

[0004] The purpose of this invention is to provide a shoe machine pressure calibration device to solve the above-mentioned problems.

[0005] The technical solution of this utility model is implemented as follows: This utility model provides a shoe machine pressure calibration device, including a base and a pressure detection device. The pressure detection device is detachably fixed on the base. Electric push rods are detachably fixed on both sides of the base. Positioning members are also slidably provided on both sides of the base. A connecting mechanism is provided between the positioning members and the electric push rods. When the telescopic end of the electric push rod extends, the positioning member slides downward. Pressure plates are fixed on both sides of the bottom of the base. When the telescopic end of the electric push rod is at the end of its stroke, the positioning member presses against the pressure plate.

[0006] In one embodiment, the telescopic end of the electric push rod slides in the lateral direction. The connecting mechanism includes a first movable rod, a second movable rod, and a third movable rod that are hinged one to the other. It also includes a limiting rod. The end of the first movable rod away from the second movable rod is hinged to the telescopic end of the electric push rod. The end of the third movable rod away from the second movable rod is hinged to a positioning member. One end of the limiting rod is fixed to the base, and the other end is hinged to the middle of the second movable rod.

[0007] In one embodiment, guide rods are fixed on both sides of the base, and the positioning member is slidably connected to the guide rods.

[0008] In one embodiment, the electric push rod has a bidirectional telescopic stroke, and the connecting mechanism and guide rod are also provided in two sets and symmetrically distributed on both sides of the positioning member.

[0009] In one embodiment, the pressure plate has a groove, and a pressure block is embedded in the groove that can move up and down. The positioning member can be separated and pressed against the pressure block.

[0010] In one embodiment, the pressure block includes a pressure layer and an elastic layer, which are bonded together vertically, with the elastic layer facing the groove and the pressure layer facing the positioning element.

[0011] The advantages or beneficial effects of the above technical solutions include at least the following: In this invention, when it is necessary to adjust the pressure parameters of the shoe press machine, the base with the pressure detection device is placed in the middle of the shoe press machine's worktable. Then, the extension end of the electric push rod is controlled to extend, so that the positioning part slides downward with the cooperation of the connecting mechanism. When the electric push rod extends to the end of its stroke, the positioning part presses against the pressure plate. At this time, the positioning part presses down on the pressure plate, thereby increasing the friction between the pressure plate and the shoe press machine's worktable, thus clamping the base. When the shoe press machine's pressing part extends out to press against the pressure detection device, it can be stably assembled on the shoe press machine's worktable, making the detected pressure value more accurate. Therefore, the shoe press machine pressure calibration device in this invention does not require drilling holes or installing studs on the shoe press machine; it can be stably fixed on the shoe press machine on its own, further improving its practicality.

[0022] Reference Figure 1A shoe press machine pressure calibration device includes a base 1 and a pressure detection device 2. The pressure detection device 2 is detachably fixed to the base 1. Electric push rods 3 are detachably fixed to both sides of the base 1. Positioning members 4 are also slidably mounted on both sides of the base 1. A connecting mechanism 5 is provided between the positioning members 4 and the electric push rods 3. When the extension end of the electric push rod 3 is extended, the positioning members 4 slide downward. Pressure plates 6 are fixed to both sides of the bottom of the base 1. When the extension end of the electric push rod 3 is at the end of its stroke, the positioning members 4 press against the pressure plates 6. With this configuration, when it is necessary to adjust the pressure parameters of the shoe press machine, the base 1 with the pressure detection device 2 is placed in the middle of the shoe press machine worktable, and then the extension and retraction of the electric push rods 3 are controlled. The end extends so that the positioning part 4 slides downward with the cooperation of the connecting mechanism 5. When the electric push rod 3 extends to the end of its stroke, the positioning part 4 presses against the pressure plate 6. At this time, the positioning part 4 presses down on the pressure plate 6, thereby increasing the friction between the pressure plate 6 and the worktable of the shoe press machine, thus clamping the base 1. When the pressing part of the shoe press machine extends out of the pressing pressure detection device 2, it can be stably assembled on the worktable of the shoe press machine, making the detected pressure value more accurate. Therefore, the shoe press machine pressure calibration device in this utility model does not need to drill holes or install studs on the shoe press machine. It can be fixed on the shoe press machine relatively stably by itself. Therefore, compared with the existing pressure calibration device, this utility model is more practical.

[0023] In one specific embodiment, the pressure detection device 2 includes a base and multiple pressure blocks 9. The pressure blocks 9 are detachably fixed on the four sides (front, back, left, right) and top of the base, and each pressure block 9 is equipped with a pressure sensor. The pressure sensor is electrically connected to the controller. When the base 1 is fixed, when the pressing part of the shoe press machine extends to press against the pressure block 9, the pressure sensor on it can accurately detect the pressure acting on the pressure block 9 and reflect the parameters to the controller in real time, so as to facilitate the operator to adjust the pressure parameters of the shoe press machine. The relevant structure of the above device is common knowledge to those skilled in the art, so the specific structure is not explicitly shown in the drawings.

[0024] Reference Figure 1The telescopic end of the electric push rod 3 slides laterally. The connecting mechanism includes a first movable rod 501, a second movable rod 502, and a third movable rod 503 that are hinged one to one, and also includes a limiting rod 504. The end of the first movable rod 501 away from the second movable rod 502 is hinged to the telescopic end of the electric push rod 3. The end of the third movable rod 503 away from the second movable rod is hinged to the positioning member 4. One end of the limiting rod 504 is fixed to the base 1, and the other end is hinged to the middle of the second movable rod 502. With this configuration, when the telescopic end of the electric push rod 3... When extended, the first movable rod 501 is displaced outward. The first movable rod 501 then pushes the second movable rod 502 to one end connected to it. Since the middle part of the second movable rod 502 is hinged to the limiting rod 504, under the push of the first movable rod 501, the second movable rod 502 rotates around the middle part as the fulcrum, causing its other end to rotate downward and push the third movable rod 503. Therefore, the third movable rod 503 can move downward with the hinge point of the second movable rod 502 as the fulcrum, thereby pushing the positioning member 4 downward and pressing against the pressure plate 6.

[0025] Reference Figure 1 Guide rods 7 are fixed on both sides of the base 1. The positioning member 4 is slidably connected to the guide rods 7. With this setting, under the guidance of the guide rods 7, the positioning member 4 can only slide up and down along the guide rods 7. This not only prevents the positioning member 4 from shifting during the up and down sliding process, but also allows the third movable rod 503 to directly push the positioning member 4 to slide up and down when it is displaced.

[0026] In one specific embodiment, a connector is fixedly provided on the side of the positioning member 4 near the guide rod 7, and a groove is provided on the guide rod 7. The connector is slidably embedded in the groove, so that the positioning member 4 can only slide up and down along the guide rod 7. At the same time, since the side of the connector in the lateral direction is in parallel contact with the inner groove surface of the groove, the connector cannot make lateral displacement, thereby preventing the positioning member 4 from sliding up and down. Furthermore, in order to reduce the sliding friction between the side of the connector and the inner groove surface of the groove, a roller is fixedly provided on the side of the connector. One side of the roller abuts against the inner groove surface of the groove, so that the side of the connector does not directly contact the inner groove surface of the groove, avoiding severe wear and gaps on the surface in contact with the groove under long-term sliding friction, so that the connector can shift laterally at the gaps when sliding up and down. The above structures are common knowledge to those skilled in the art, so the specific structures are not explicitly shown in the drawings.

[0027] Reference Figure 1The electric push rod 3 has a bidirectional telescopic stroke, and the connecting mechanism 5 and the guide rod 7 are also provided in two sets and symmetrically distributed on both sides of the positioning member 4. With this arrangement, the downward force is applied to the positioning member 4 from both sides. This not only reduces the wear of the connecting mechanism 5 caused by the reaction force of the positioning member 4 during the movement, but also further ensures that the positioning member 4 can only slide vertically up and down, preventing the positioning member 4 from accidentally shifting during the sliding process.

[0028] Reference Figure 1 and Figure 2 The pressure plate 6 has a groove 8, in which a pressure block 9 is embedded that can move up and down. The positioning member 4 can be separated and presses against the pressure block 9. With this arrangement, when the positioning member 4 slides down and presses against the pressure block 9, the pressure block 9 can generate a downward preload, so that the pressure block 9 can further compact the pressure plate 6. At the same time, because the positioning member 4 presses against the pressure plate 6 through the pressure block 9, rather than directly pressing against the pressure plate 6, the pressure block 9 can share some of the wear when the positioning member 4 is pressed down, thereby reducing the probability of the connection between the pressure plate 6 and the base 1 breaking due to repeated stress.

[0029] Reference Figure 3 The pressure block 9 includes a pressure layer 901 and an elastic layer 902, which are bonded together vertically. The elastic layer 902 faces the groove 8, and the pressure layer 901 faces the positioning member 4. With this arrangement, the elastic layer 902 can generate elastic deformation under the pressure of the positioning member 4 to offset a certain amount of wear, thereby extending the service life of the pressure block 9.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
