Description

Technical Field

[0001] This utility model relates to the field of encoder installation, and in particular to a connection mechanism and encoder installation device. Background Technology

[0002] An encoder is a high-precision sensor used to convert linear displacement or rotational angle information during equipment operation, and it is an important component in controlling equipment motion. Encoders are widely used in many fields such as metallurgical industrial automation, robotics, CNC machine tools, automatic detection and measurement. Currently, the main installation method is coaxial rigid connection mounting. This mounting method makes the encoder susceptible to vibration under the influence of external equipment, thus affecting the stability of the encoder during operation and reducing its service life. Summary of the Invention

[0003] Therefore, the technical problem to be solved by this utility model is that: after the existing encoder is installed, it is easy to shake under the action of the connecting shaft, which affects the normal use of the encoder.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a connecting mechanism, which includes an encoder body and a rotating component disposed at the center of the encoder shaft. The rotating component is provided with a limiting groove and a connecting rod sleeved inside the rotating component. The connecting rod is provided with a limiting rod that engages with the limiting groove and a damping component for reducing the vibration amplitude of the encoder body. One end of the connecting rod is provided with a connecting sleeve that connects to a rigid connecting shaft.

[0005] As a preferred embodiment of the connecting mechanism of this utility model, the connecting rod is provided with a limiting insertion hole that penetrates the connecting rod, and the limiting insertion hole is provided with a trapezoidal anti-detachment hole.

[0006] As a preferred embodiment of the connection mechanism of this utility model, the smallest end of the anti-detachment hole is far away from the encoder body and has the same diameter as the limiting insertion hole. The end of the limiting rod that is far away from the encoder body slides into the anti-detachment hole and is fixedly installed with an anti-detachment cone block, and the anti-detachment cone block abuts against the inner wall of the anti-detachment hole.

[0007] As a preferred embodiment of the connecting mechanism of this utility model, the damping component includes a damping arc plate that abuts against the inner wall of the rotating component, and the inner arc surface of the damping arc plate is provided with a bent plate that is fixedly connected to the connecting rod.

[0008] As a preferred embodiment of the connecting mechanism of this utility model, a damping cavity is constructed between the inner arc surface of the bending plate and the damping arc plate and the connecting rod.

[0009] As a preferred embodiment of the connecting mechanism of this utility model, the connecting sleeve is provided with a connecting hole, and the two ends of the connecting hole that contact the outer wall of the connecting sleeve are provided with fastening grooves.

[0010] The beneficial effects of the connection mechanism of this utility model are as follows: through the cooperation of the connecting sleeve and connecting rod, the connection between the encoder body and the rigid connecting shaft is realized, realizing the operation of converting physical signals into electrical signals. Through the setting of the damping component, the impact force that the encoder may be subjected to is actively absorbed, thereby reducing the impact force on the rotating parts and the encoder body, thus protecting the encoder body and increasing the service life of the encoder body.

[0011] Another objective of this invention is to provide an encoder mounting device that solves the problem of difficulty in adjusting the mounting position of the encoder body.

[0012] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: an encoder mounting device, which includes a connecting mechanism; and a mounting component, including a U-shaped plate connected to the encoder body, wherein an L-shaped plate connected to an external device is detachably mounted on one end of the U-shaped plate.

[0013] As a preferred embodiment of the encoder mounting device of this utility model, the U-shaped plate has threaded holes at both ends, and the L-shaped plate has mounting grooves that correspond to the threaded holes on the U-shaped plate.

[0014] In a preferred embodiment of the encoder mounting device of this utility model, a mounting collar is provided between the U-shaped plate and the encoder body, and the mounting collar is provided with a first protrusion connected to the encoder body and a second protrusion connected to the U-shaped plate.

[0015] As a preferred embodiment of the encoder mounting device of this utility model, mounting bolts for detachable connection are provided between the threaded hole and the mounting groove, between the first protrusion and the encoder body, and between the U-shaped plate and the second protrusion.

[0016] The beneficial effects of the encoder installation device of this utility model are as follows: by setting up the U-shaped plate and the L-shaped plate, the encoder body can be installed.

[0023] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0024] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0025] This embodiment provides a connection mechanism, such as Figure 1 As shown, a rotating component 2 is rotatably mounted on the encoder body 1. A connecting rod 4 is sleeved inside the rotating component 2. One end of the connecting rod 4 is provided with a connecting sleeve 44 that connects to a rigid connecting shaft. Figure 4 As shown, the inner wall of the rotating part 2 is provided with a limiting groove 3, in which a limiting rod 41 is engaged.

[0026] An encoder is a sensor device that converts physical signals (such as rotation angle, linear displacement, etc.) into electrical signals (such as pulses, codes, etc.). Therefore, when the rigid connecting shaft rotates, it will drive the connecting sleeve 44, which is detachably connected to it, to rotate. Since the connecting sleeve 44 is fixed to the connecting rod 4, it will synchronously drive the connecting rod 4 and the limiting rod 41 set on it to rotate. The limiting rod 41 drives the rotating part 2 to rotate by interlocking with the upper limit slot 3 of the rotating part 2, thereby driving the operation of the internal structure of the encoder body 1, realizing the operation of converting physical signals into electrical signals.

[0027] like Figure 2As shown, the damping component 45 includes a damping arc plate 451 that contacts the rotating component 2. Two bent plates 452, which are fixedly connected to the connecting rod 4, are fixedly installed on the inner arc surface of the damping arc plate 451. A damping cavity 453 is constructed between the bent plates 452, the inner arc surface of the damping arc plate 451, and the connecting rod 4. Figure 2 As shown, the damping cavity 453 is rhomboid in shape.

[0028] Therefore, when the connecting rod 4 begins to shake under the action of the rigid connecting shaft, the damping arc plate 451 will come into contact with the inner side of the rotating part 2. At this time, the damping cavity 453 will contract towards the connecting rod 4 under the action of the rebound force of the rotating part 2. Thus, by contracting the damping cavity 453, the impact force of the rotating part 2 can be absorbed, thereby reducing the impact force on the rotating part 2 and the encoder body 1, thus protecting the encoder body 1 and increasing the service life of the encoder body 1.

[0029] In addition, both the connecting rod 4 and the connecting sleeve 44 can be made of nylon, because nylon products have a certain degree of flexibility, which can further buffer the impact of vibration directly on the encoder body 1 during use.

[0030] like Figure 3 As shown, the connecting rod 4 is provided with several limiting holes 42 for accommodating the limiting rod 41, and from... Figure 2 It can also be seen that the limiting insertion hole 42 has a trapezoidal anti-detachment hole 43, and the smallest end of the anti-detachment hole 43 is far away from the limiting rod 41. The limiting rod 41 slides to one end of the anti-detachment hole 43 and is fixedly installed with an anti-detachment cone block 411. Figure 2 It can be seen that the largest end of the anti-detachment cone block 411 and the largest end of the anti-detachment hole 43 are in contact with each other.

[0031] Because both the connecting rod 4 and the connecting sleeve 44 can be made of nylon, when disassembling the limiting rod 41, the limiting rod 41 can be pressed downwards, causing the anti-detachment cone 411 located in the anti-detachment hole 43 to press against the inner wall of the anti-detachment hole 43. This forces the anti-detachment hole 43 and the limiting insertion hole 42 to deform, increasing their own diameter and facilitating the passage of the limiting rod 41 and the anti-detachment cone 411. During installation, the anti-detachment cone 411, which is fixedly installed with the limiting rod 41, can also be inserted into the anti-detachment hole 43 in the same way, without external force. In this case, the diameter of the smallest end of the anti-detachment hole 43 is smaller than the diameter of the largest end of the anti-detachment cone 411. Therefore, the anti-detachment cone 411 will drive the limit rod 41 to be installed on the connecting rod 4. When the connecting rod 4 rotates, the encoder body 1 will be driven to run through the mutual engagement of the limit rod 41 and the limit slot 3. This installation method allows the limit rod 41 and the connecting rod 4 to be detachably connected, which expands the scope of use of the equipment. Because the encoder body 1 of different specifications is of different sizes, this setting is convenient for installing encoder body 1 of different specifications.

[0032] Furthermore, the multiple limit sockets 42 allow for the addition of multiple encoder bodies 1, preventing the entire device's operating speed from being unmonitored if any encoder body 1 malfunctions.

[0033] like Figure 3 As shown, the connecting sleeve 44 is provided with several connecting holes 441. During installation, the rigid connecting shaft can be inserted into the connecting sleeve 44 first, and then the rigid connecting shaft can be connected to the connecting sleeve 44 by the engagement of screws with the connecting holes 441. Figure 3 As can be seen, the diameter of each connecting hole 441 is different. This design allows the connecting sleeve 44 to be installed with screws of different rigid connecting shafts, further increasing the scope of application of the equipment and facilitating its promotion.

[0034] In addition, such as Figure 3 As shown, both ends of the connecting hole 441 and the contact end with the outer wall of the connecting sleeve 44 are provided with fastening grooves 442. Because the outer surface of the connecting rod 4 is arc-shaped, the contact area between the screw and it is low, the fastening is not high, and it is easy to loosen. Therefore, in this embodiment, fastening grooves 442 are provided so that the contact surface between the screw and it is flat, thereby increasing the contact area of ​​the screw and increasing the connection stability between the rigid connecting shaft and the connecting sleeve 44.

[0035] This embodiment also provides an encoder mounting device, such as... Figure 5 As shown, a U-shaped plate 51 is mounted on the encoder body 1. One end of the U-shaped plate 51 has an L-shaped plate 52 for connecting to an external device. Therefore, during installation, the U-shaped plate 51 can be connected to the encoder body 1 first, and then the L-shaped plate 52 can be welded to the external device. Finally, the L-shaped plate 52 and the U-shaped plate 51 can be installed together using mounting bolts 53, thus completing the connection of the encoder body 1. Figure 5 As shown, the mounting slot 54 on the L-shaped plate 52 is elongated, which allows the operator to adjust the mounting position of the encoder body 1 as needed, making the encoder installation more convenient.

[0036] like Figure 5 As shown, an mounting collar 55 is fitted onto one end of the encoder body 1. A first protrusion 56 and a second protrusion 57 are vertically arranged on the mounting collar 55, and both the first protrusion 56 and the second protrusion 57 are fixedly connected to the mounting collar 55. Furthermore, mounting bolts 53 for detachable connection are provided between the first protrusion 56 and the encoder body 1, as well as between the U-shaped plate 51 and the second protrusion 57, so that the encoder body 1 and the U-shaped plate 51 are connected together, which facilitates subsequent installation.

[0037] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
