Description

Technical Field

[0001] The utility model belongs to the technical field of disassembly tool design and relates to an encoder disassembly device. Background Art

[0002] The encoder is a device used to detect the movement of the motor on the automated production line. It is widely used in automated equipment in the tobacco industry, such as high-bay warehouse stackers, belt scale belt motors, etc. The encoder is installed on the motor spindle and moves with the spindle to detect the spindle's movement state. Therefore, the correct installation and stable operation of the encoder directly affect production safety and product quality.

[0003] When installing the encoder, first insert it into the hole of the motor spindle, and then use the expansion screws in the encoder detection shaft to expand and tighten it with the motor spindle, so that the encoder detection shaft moves with the motor spindle. After long-term use of the encoder, the expansion screws will rust, the encoder detection shaft will be damaged, and the mating parts will stick, which will cause the encoder detection shaft to get stuck in the motor spindle and cannot be removed normally.

[0004] When an encoder is stuck, it needs to be forcibly removed with pliers, which can easily lead to damage to the encoder detection shaft, wear of the motor spindle hole, bending of the encoder detection shaft, etc., affecting the subsequent use of the motor and encoder. In addition, it is labor-intensive, time-consuming, and troublesome to operate. Currently, there is no suitable tool to conveniently and effectively remove the encoder. Utility Model Content

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0025] like Figure 1-3 As shown, an embodiment of the utility model provides an encoder disassembly device, including: a screw rod 3, a driving mechanism, a clamping assembly and a support cover 8; the screw rod 3 is vertically arranged, with its upper end connected to the driving mechanism and its lower end connected to the support cover 8, and the clamping assembly is sleeved on the outside of the screw rod 3.

[0026] The driving mechanism is in transmission connection with the screw rod 3 to drive the screw rod 3 to rotate axially.

[0027] In the embodiment of the utility model, the driving mechanism uses a first bevel gear 1 and a second bevel gear 2 that mesh with each other, wherein the first bevel gear 1 is connected to the upper end of the screw 3, and a bevel gear set housing 12 is installed outside the first bevel gear 1 and the second bevel gear 2. This method not only reduces the torque required for disassembly, but also can adjust the direction of the second bevel gear 2 according to the working space, thereby adjusting the direction of the wrench when rotating the screw 3, solving the problem of inconvenient operation in a small space.

[0028] The first bevel gear 1 and the screw rod 3 can be disassembled, so it is convenient to replace other driving tools to rotate the screw rod 3.

[0029] A sliding block is sleeved on the outer side of the screw rod 3, and the clamping assembly includes a plurality of hook claws 5, and the plurality of hook claws 5 are fixedly connected to the sliding block at equal intervals.

[0030] In the embodiment of the utility model, three hooks 5 are provided, so a triangular slider 4 is used, a hook 5 is fixed at each corner of the triangular slider 4, and the triangular slider 4 is threadedly connected with the screw rod 3. When the encoder disassembly device in the embodiment of the utility model is used, the encoder 7 is fixed by the three hooks 5, and the drive mechanism drives the screw rod 3 to rotate axially. Because the three hooks 5 are restricted by the support cover 8, the triangular slider 4 cannot rotate with the screw rod 3, but moves upward along the thread of the screw rod 3, driving the encoder 7 in the hook 5 to move upward and be taken out along the length direction of the motor main shaft 9.

[0031] As an equivalent replacement, a ball screw can be used to replace the screw 3 and the slider. The ball screw can convert rotary motion into linear motion. Specifically, the ball screw includes a screw and a screw retaining bearing sleeved outside the screw. The hook 5 is fixedly connected to the screw retaining bearing. When the encoder 7 is removed, the encoder 7 is fixed by the hook 5. The drive mechanism drives the screw to rotate axially. The ball screw converts the axial rotation of the screw into the linear motion of the screw retaining bearing along the screw, which can drive the hook 5 and the encoder 7 in the hook 5 to move upward.

[0032] The top of the support shell 8 is connected to the lower end of the screw rod 3 , and a through slot is provided on the support shell 8 , through which the hook 5 extends into the support shell 8 to clamp the encoder 7 .

[0033] The length of the through groove needs to be greater than the depth of the encoder 7 inserted into the hole of the motor spindle. In the embodiment of the utility model, the through groove is arranged from the bottom of the support cover 8 to the middle of the support cover 8, and the number of through grooves is consistent with the number of claws 5; and it is connected to the screw rod 3 through a spherical roller bearing 6 to withstand the axial force when the screw rod 3 rotates.

[0034] The driving mechanism drives the screw rod 3 to rotate axially, and the triangular slider 4 is restricted by the support cover 8 and cannot rotate with the screw rod 3. The resistance generated in the process is applied to the support cover 8. The support cover 8 is close to the upper end surface of the motor housing 10, which ensures that the screw rod 3 is always vertical during the extraction of the encoder 7, and the encoder 7 is taken out along the axial direction of the motor spindle 9 without tilting during the process, thereby protecting the motor spindle 9 and the encoder detection shaft.

[0035] The lower end of the support cover 8 is provided with an ear plate 11 perpendicular to the screw rod 3 to increase the contact area between the support cover 8 and the motor.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present disclosure / application.
