Description

Technical Field

[0001] The utility model belongs to the technical field of encoder bearing installation, in particular to a controllable pressure installation device for an encoder bearing. Background Art

[0002] An encoder is a device that compiles and converts signals (such as bit streams) or data into signal forms that can be used for communication, transmission, and storage. The encoder converts angular displacement or linear displacement into electrical signals. The former is called a code disk and the latter is called a code ruler.

[0003] Some encoders require bearings to be installed, but the machines currently used for encoder bearing installation on the market are inconvenient to use. They are inaccurate when adjusting the distance from the encoder, which can easily cause errors in the subsequent installation of the encoder bearing. Utility Model Content

[0004] The utility model aims to provide a controllable pressure installation device for an encoder bearing, which solves the existing problems by providing a rotation adjustment mechanism.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a controllable pressure installation device for an encoder bearing, comprising a machine body, an encoder main body is arranged on the top of the machine body, a pressure device main body is slidably connected to the front end of the machine body, an operating rod is arranged on the side of the pressure device main body, a pressure sensor is arranged on the bottom of the pressure device main body, a pressure head is arranged on the bottom of the pressure sensor, a rotation adjustment mechanism is arranged inside the machine body, a movable seat, a threaded rod, a rotating shaft and a rotating rod of the rotation adjustment mechanism are arranged, the movable seat is slidably connected to the inside of the machine body, the front end of the movable seat is fixedly connected to the pressure device main body, the threaded rod is rotatably connected to the inside of the machine body, the movable seat is threadedly connected to the threaded rod, a bevel gear A is fixedly connected to the surface of the threaded rod, the rotating shaft passes through and is rotatably connected to the side of the machine body, one end of the rotating shaft is fixedly connected to the bevel gear B, the other end of the rotating shaft is fixedly connected to the slave gear, the rotating rod is rotatably connected to the side of the machine body, the surface of the rotating rod is fixedly connected to the main gear, and an anti-mistouch rotation mechanism is arranged on the side of the rotating rod.

[0007] Furthermore, a display screen is provided at the front end of the pressure device body, and the pressure sensor is electrically connected to the display screen at the front end of the pressure device body through a wire. After the pressure sensor detects the pressure, it transmits the information to the display screen at the front end of the pressure device body through the wire.

[0008] Furthermore, one end of the rotating shaft close to the bevel gear B is located inside the machine body, and the bevel gear A is vertically meshed with the bevel gear B, and the rotation of the bevel gear B will drive the bevel gear A to rotate.

[0009] Furthermore, the slave gear is meshed with the main gear, and the diameter of the main gear is smaller than that of the slave gear. The rotation of the main gear drives the slave gear to rotate, and the smaller the diameter of the main gear is, the slower the speed at which the slave gear rotates per circle.

[0010] Furthermore, the anti-accidental-touch rotation mechanism includes a slide groove, a slider is slidably connected inside the slide groove, a connecting rod is fixedly connected to the side of the slider, a turning handle is fixedly connected to the side of the connecting rod away from the sliding, a return spring is sleeved on the surface of the connecting rod, a card groove is provided on the inner wall of the slide groove, a groove is provided on the surface of the slider, a compression spring is fixedly connected to the inner wall of the groove, and an arc block is slidably connected to the inside of the groove via the compression spring.

[0011] Furthermore, the end of the arc block away from the groove initially contacts the inner wall of the slide groove, and the compression spring is in a taut state in the initial state. When the compression spring rebounds, it drives the arc block to pop out of the groove.

[0012] Furthermore, the size of the slot opening is equal to that of the groove opening, and the arc surface of the arc block faces leftward. When the groove and the slot fit together, the arc block will be inserted into the slot, and at this time, the arc surface of the arc block will retract into the groove when squeezed.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model is provided with a rotation adjustment mechanism, so that when it is necessary to adjust the distance between the pressure device body and the bottom pressure head and the encoder, the rotating rod can be rotated. At this time, the cooperation of the main gear, the slave gear, the bevel gear A, the bevel gear B, the threaded rod and other components will drive the moving seat to move up and down, thereby adjusting the height of the pressure device body, and the adjustment is more accurate.

[0015] 2. The utility model is provided with an anti-accidental-touch rotation mechanism, so that the height of the pressure device body can be adjusted only when the handle is pulled out and then rotated, and the handle will automatically rebound after the handle is released. At this time, the rotation of the handle will not drive the rotation of the rod, which effectively prevents the height of the pressure device body from changing due to accidental touch, affecting the installation of the encoder body 2 bearing.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] A display screen is provided at the front end of the pressure device body 3, and the pressure sensor 5 is electrically connected to the display screen at the front end of the pressure device body 3 through a wire. After the pressure sensor 5 detects the pressure, it transmits the information to the display screen at the front end of the pressure device body 3 through the wire.

[0028] One end of the rotating shaft 74 close to the bevel gear B75 is located inside the machine body 1, and the bevel gear A73 is vertically meshed with the bevel gear B75. The rotation of the bevel gear B75 will drive the bevel gear A73 to rotate.

[0029] The slave gear 76 meshes with the main gear 78, and the diameter of the main gear 78 is smaller than that of the slave gear 76. The rotation of the main gear 78 will drive the slave gear 76 to rotate, and the smaller diameter of the main gear 78 drives the slave gear 76 to rotate one circle at a slower speed.

[0030] The anti-accidental-touch rotation mechanism 8 includes a slide groove 89, a slider 81 is slidably connected inside the slide groove 89, a connecting rod 82 is fixedly connected to the side of the slider 81, a turning handle 83 is fixedly connected to the side of the connecting rod 82 away from the slider 81, a return spring 84 is sleeved on the surface of the connecting rod 82, a card groove 85 is provided on the inner wall of the slide groove 89, a groove 86 is provided on the surface of the slider 81, a compression spring 87 is fixedly connected to the inner wall of the groove 86, and an arc block 88 is slidably connected to the inside of the groove 86 through the compression spring 87.

[0031] The end of the arc block 88 away from the groove 86 initially contacts the inner wall of the slide groove 89 , and the compression spring 87 is initially in a tensioned state. When the compression spring 87 rebounds, it drives the arc block 88 to pop out of the groove 86 .

[0032] The opening size of the slot 85 is equal to that of the groove 86, and the arc surface of the arc block 88 faces leftward. When the groove 86 and the slot 85 are in contact with each other, the arc block 88 will be inserted into the slot 85, and at this time, the arc surface of the arc block 88 will retract into the groove 86 when being squeezed.

[0033] A specific application of this embodiment is: when it is necessary to install the bearing on the encoder body 2, the encoder body 2 is placed on the machine body 1, and the operating rod 4 is pressed down. At this time, the pressure sensor 5 and the pressure head 6 at the bottom of the pressure device body 3 will move downward, and the bearing or shaft body will be pressed into the bearing hole of the encoder body 2 through the pressure head 6. After the pressure sensor 5 detects the pressure, it will transmit the information to the display screen at the front end of the pressure device body 3 through the wire to prevent the operator from damaging the encoder body 2 with excessive force. When the height of the pressure device body 3 needs to be adjusted, the rotating rod 77 can be rotated. The rotation of the rotating rod 77 drives the main gear 78 to rotate. The rotation of the main gear 78 drives the slave gear 76 to rotate. The main gear 78 has a smaller diameter and drives the slave gear 76 to rotate one circle more slowly. The slow rotation of the slave gear 76 drives the rotating shaft 74 to rotate slowly. The slow rotation of the rotating shaft 74 drives the bevel gear B75 to rotate slowly. The slow rotation of the bevel gear B75 drives the bevel gear A73 to rotate slowly. The threaded rod 72 is driven to rotate slowly, and the slow rotation of the threaded rod 72 will drive the moving seat 71 to move upward or downward, so as to slowly adjust the height of the pressure device body 3. When it is necessary to drive the rotating rod 77, the turning handle 83 can be pulled out to the right. Pulling out the turning handle 83 to the right will drive the slider 81 to move to the right through the connecting rod 82. The rightward movement of the slider 81 will squeeze the return spring 84 to make it tight. When the slider 81 moves to the right and drives the groove 86 to fit with the card slot 85, the compression spring 87 will rebound and drive the arc block 88 When the handle 83 is inserted into the card slot 85, the handle 83 will be rotated through the arc block 88 when it is turned. After the handle 83 is released, the return spring 84 will rebound and drive the handle 83 and the slider 81 to move to the left and restore. When the slider 81 moves to the left, the arc surface of the arc block 88 is squeezed and retracts into the groove 86 again. At this time, when the handle 83 is turned again, it will not drive the rotating rod 77 to rotate, which effectively prevents the accidental touch from causing the height of the pressure adjustment device body 3 to change and affecting the installation of the encoder body 2 bearing.
