Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic couplings, and particularly relates to a calibration device for installing a hydraulic coupling. Background Technique

[0002] A hydraulic coupling, also known as a hydraulic coupler, is a hydraulic transmission device used to connect a power source (usually an engine or a motor) to a working machine and transmit torque by changing the momentum moment of a liquid. The hydraulic coupling is a non-rigid coupling with liquid as the working medium. The pump wheel and the turbine of the hydraulic coupling form a closed working chamber in which the liquid can circulate. The pump wheel is installed on the input shaft, and the turbine is installed on the output shaft. The two wheels are semi-circular rings with many blades arranged radially. They are coupled face to face, do not touch each other, and there is a gap of 3 mm to 4 mm in the middle, forming an annular working wheel.

[0003] According to a disclosed calibration device for installing a hydraulic coupling (publication number: CN 216306643 U), it includes a horizontal plate. Installation seats are fixedly installed at both the left and right ends of the horizontal plate. A support is fixedly installed at the bottom end of the horizontal plate. The inner bottom end of the support is rotatably connected to a movable rod that penetrates through and extends to the top end of the horizontal plate.

[0004] However, in the above design, through the mutual cooperation of components such as the horizontal plate and the installation seats, it is difficult to make the bearing stably located at the center of the inner wall of the output shaft, resulting in the bearing not being accurately located at the center and unable to be fixed by the clamping plate. Therefore, we propose a calibration device for installing a hydraulic coupling. Summary of the Invention

[0005] The purpose of the utility model is to provide a calibration device for installing a hydraulic coupling. Through the mutual cooperation of components such as the clamping plate, the round shaft, the chute, and the gear disk, when the gear disk rotates counterclockwise, it forces the round shaft to slide on the inner wall of the special-shaped groove, so that the round shaft drives the clamping plate to slide on the inner wall of the groove, thereby clamping and positioning the connecting bearing by the clamping plate, enabling the bearing to be stably located at the center of the inner wall of the output shaft, enabling the bearing to be accurately located at the center and fixed by the clamping plate, achieving the calibration effect while realizing the fixing function, improving the installation efficiency of the staff, and making the installation process fast and simple, solving the existing problems.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a calibration device for the installation of a hydraulic coupling, which comprises a machine body and an input shaft. The input shaft is fixedly connected to the side surface of the machine body. A fixing component is fixedly connected to the circumferential surface of the machine body. An output shaft is fixedly connected to the side surface of the machine body. A calibration fixing device is fixedly connected to the circumferential surface of the output shaft. The calibration fixing device comprises a groove which is opened on the circumferential surface of the output shaft. A clamping plate is slidably connected to the inner wall of the groove. A round shaft is fixedly connected to the side surface of the clamping plate.

[0008] Further, a sliding groove is opened on the circumferential surface of the output shaft. A stress shaft is slidably connected to the inner wall of the sliding groove. One end of the stress shaft far away from the sliding groove is fixedly connected with a gear disk. A special-shaped groove is opened on the side surface of the gear disk. A stress rod is fixedly connected to the circumferential surface of the gear disk. Such a design is beneficial to the fact that when the stress shaft is stressed, it can slide on the inner wall of the sliding groove.

[0009] Further, the round shaft is slidably connected to the inner wall of the special-shaped groove. A plurality of special-shaped grooves are provided and are circumferentially arrayed on the circumferential surface of the gear disk. Such a design is beneficial to the round shaft sliding on the inner wall of the special-shaped groove.

[0010] Further, an auxiliary device is arranged on the circumferential surface of the output shaft. The auxiliary device comprises a rotating shaft which is rotatably connected to the circumferential surface of the output shaft. A clamping block is fixedly connected to the circumferential surface of the rotating shaft. An acting groove is opened on the inner wall of the special-shaped groove. Such a design is beneficial to the clamping block realizing an upward arc-shaped movement through the rotating shaft.

[0011] Further, a blocking block is fixedly connected to the inner wall of the acting groove. A rectangular groove is opened on the circumferential surface of the round shaft. A spring is fixedly connected to the inner wall of the rectangular groove. One end of the spring far away from the inner wall of the rectangular groove is fixedly connected with a stress block. Such a design is beneficial to the stress block sliding on the inner wall of the rectangular groove through the spring.

[0012] Further, a plurality of blocking blocks are provided and are linearly arrayed on the inner wall of the acting groove. The stress block is slidably connected to the inner wall of the rectangular groove. One end of the stress block is arranged as an adaptive arc surface. Such a design is beneficial to the blocking block being able to clamp the stress block.

[0013] Further, a plurality of clamping plates are provided and are circumferentially arrayed on the circumferential surface of the output shaft. The side cross-section of the clamping plate is arranged as special-shaped. Such a design is beneficial to the clamping plate clamping the bearing to be connected.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model realizes the following functions through the cooperation of components such as clamping plates, round shafts, sliding grooves, and toothed disks. When the toothed disk rotates counterclockwise, it forces the round shaft to slide on the inner wall of the special-shaped groove, causing the round shaft to drive the clamping plate to slide on the inner wall of the groove. As a result, the clamping plate clamps and positions the connecting bearing, enabling the bearing to be stably located at the center of the inner wall of the output shaft. The bearing can be accurately positioned at the center and fixed by the clamping plate, achieving the calibration effect while fulfilling the fixing function, improving the installation efficiency of the staff, and making the installation process fast and simple.

[0016] 2. The utility model realizes the following functions through the cooperation of components such as clamping blocks, rotating shafts, springs, and force-receiving blocks. When the toothed disk rotates counterclockwise to the satisfaction of the staff, the round shaft is placed on the inner wall of the special-shaped groove. During the movement of the round shaft, the arc surface of the force-receiving block contacts the blocking block, causing the force-receiving block to be forced to retract into the inner wall of the rectangular groove through the spring. When the arc surface of the force-receiving block no longer contacts the blocking block, the blocking block can block the force-receiving block, further hindering the movement of the toothed disk and preventing the toothed disk from rotating in reverse. This plays an auxiliary role in the calibration and fixing device and avoids the bearing losing the clamping force and affecting subsequent work.

[0017] Of course, it is not necessary for any product implementing the utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] A chute 54 is opened on the circumferential surface of the output shaft 4. The inner wall of the chute 54 is slidably connected with a force-bearing shaft 55. One end of the force-bearing shaft 55 away from the chute 54 is fixedly connected with a tooth disc 56. A special-shaped groove 57 is opened on the side of the tooth disc 56. A force-bearing rod 58 is fixedly connected to the circumferential surface of the tooth disc 56. Such a design is beneficial for the force-bearing shaft 55 to slide on the inner wall of the chute 54 when a force is applied.

[0028] The round shaft 53 is slidably connected to the inner wall of the special-shaped groove 57. There are several special-shaped grooves 57, and they are circumferentially arrayed on the circumferential surface of the tooth disc 56. Such a design is beneficial for the round shaft 53 to slide on the inner wall of the special-shaped groove 57.

[0029] An auxiliary device 6 is arranged on the circumferential surface of the output shaft 4. The auxiliary device 6 includes a rotating shaft 61. The rotating shaft 61 is rotatably connected to the circumferential surface of the output shaft 4. A block 62 is fixedly connected to the circumferential surface of the rotating shaft 61. An acting groove 63 is opened on the inner wall of the special-shaped groove 57. Such a design is beneficial for the block 62 to perform an upward arc movement through the rotating shaft 61.

[0030] A blocking block 64 is fixedly connected to the inner wall of the acting slot 63. A rectangular slot 65 is formed in the circumferential surface of the circular shaft 53. A spring 66 is fixedly connected to the inner wall of the rectangular slot 65. One end of the spring 66 away from the inner wall of the rectangular slot 65 is fixedly connected to a force-receiving block 67. Such a design is beneficial for the force-receiving block 67 to slide on the inner wall of the rectangular slot 65 through the spring 66.

[0031] A number of blocking blocks 64 are provided and linearly arrayed on the inner wall of the acting slot 63. The force-receiving block 67 is slidably connected to the inner wall of the rectangular slot 65. One end of the force-receiving block 67 is provided with an adaptive arc surface. Such a design is beneficial for the blocking block 64 to be able to hold the force-receiving block 67.

[0032] A number of clamping plates 52 are provided and circumferentially arrayed on the circumferential surface of the output shaft 4. The side cross-section of the clamping plate 52 is shaped in a special form. Such a design is beneficial for the clamping plate 52 to be able to clamp the bearing to be connected.

[0033] A specific application of this embodiment is as follows: First, when the staff needs to use the hydraulic coupling to install and connect the acting machine, calibration is required. The staff needs to align the bearing connected to the acting machine with the inner wall of the output shaft 4. The staff needs to rotate the force-receiving rod 58 counterclockwise, so that the gear disk 56 slides on the inner wall of the sliding slot 54 through the force-receiving shaft 55. When the gear disk 56 rotates counterclockwise, it forces the circular shaft 53 to slide on the inner wall of the special-shaped slot 57, so that the circular shaft 53 drives the clamping plate 52 to slide on the inner wall of the groove 51, thereby enabling the clamping plate 52 to clamp and position the connecting bearing, enabling the bearing to be stably located at the center of the inner wall of the output shaft 4, enabling the bearing to be accurately located at the center and fixed by the clamping plate 52, achieving the calibration effect while realizing the fixing function, improving the installation efficiency of the staff, and making the installation process fast and simple;

[0034] In the calibration fixing device 5, in order to enable the staff to avoid the reverse rotation of the gear disk 56 during the subsequent work when fixing the bearing, which may cause the bearing to lose the clamping force and affect the subsequent work. When the gear disk 56 rotates counterclockwise, the gear disk 56 contacts the block 62, causing the block 62 to move upward in an arc through the rotating shaft 61 under the force. Due to the special design of the block 62, the block 62 can cooperate with the counterclockwise rotation of the gear disk 56 and also prevent the reverse rotation of the gear disk 56. To further fix the gear disk 56, when the gear disk 56 rotates counterclockwise to the satisfaction of the staff, the round shaft 53 is placed on the inner wall of the special-shaped groove 57. During the movement of the round shaft 53, the arc surface of the force-receiving block 67 contacts the blocking block 64, causing the force-receiving block 67 to retract into the inner wall of the rectangular groove 65 through the spring 66 under the force. When the arc surface of the force-receiving block 67 no longer contacts the blocking block 64, the blocking block 64 can block the force-receiving block 67, further preventing the movement of the gear disk 56 and making the gear disk 56 unable to reverse, which plays an auxiliary role in the calibration fixing device 5 and avoids the bearing losing the clamping force and affecting the subsequent work.
