Description

Technical Field

[0001] The utility model relates to the technical field of servo motors, in particular to a sleeve-type housing for a servo motor. Background Art

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device that can convert voltage signals into torque and speed to drive the control object, and has the characteristics of high-precision control of speed and position. Its working principle is that its rotor speed is controlled by the input signal and can respond quickly. In the automatic control system, the servo motor is used as an actuator, with characteristics such as small electromechanical time constant, high linearity, and starting voltage. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is widely used in automation equipment that requires precise positioning, high-speed movement, high torque output, high stability, low noise, etc., such as CNC machine tools, semiconductor manufacturing, imaging equipment, packaging equipment, and robotics.

[0003] The core components of servo motors mainly include stators, rotors, windings, encoders and cooling fans. Traditional servo motors mostly use a housing with an installation cavity to install these components, and then lead the wires to the outside to facilitate external wiring.

[0004] However, if you want to fix and connect so many components in the same installation cavity, due to space limitations, not only the installation requirements are high and the assembly efficiency is low, but it is also impossible to ensure that the components can be connected accurately, which in turn affects the product qualification rate.

[0005] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0006] The purpose of the utility model is to overcome the above-mentioned problems of the prior art and to provide a sleeve-type housing for a servo motor, so as to solve the technical problem that the traditional servo motor adopts a single housing with a mounting cavity, which is limited by space, not only has high requirements for component installation and low assembly efficiency, but also cannot ensure that the components can be accurately connected, thereby affecting the product qualification rate.

[0007] The above objectives are achieved through the following technical solutions:

[0008] A sleeve-type housing for a servo motor comprises a first housing, wherein two ends of the first housing are respectively provided with a front end cover and a rear end cover corresponding thereto, wherein the front end cover, the first housing and the rear end cover are connected to each other to form an installation cavity, and the front end cover and the rear end cover are respectively provided with a front end cover through hole and a rear end cover through hole which can communicate with the installation cavity; a second housing which can be sleeved thereon is provided on the outer side of the first housing, and a fan cover is provided at the rear end of the second housing, and a fan cavity is formed between the fan cover, the inner cavity of the second housing and the rear end cover.

[0009] Furthermore, the outer wall of the first shell is provided with a plurality of slides, and the slides are provided with a plurality of slide grooves; the inner wall of the second shell matches the slides, and a slide buckle corresponding to the slide groove is provided on the inner wall of the second shell, and the front end of the slide buckle is slidably connected along the rear end of the slide groove.

[0010] Furthermore, mutually symmetrical limiting slide grooves are arranged on the inner wall of the slide groove, and the slide buckle includes a pair of L-shaped limiting sliding blocks facing oppositely, and the L-shaped limiting sliding blocks can perform limiting sliding with the limiting slide grooves.

[0011] Furthermore, a guide groove is further arranged on the slide platform adjacent to the slide groove, and correspondingly, a guide strip corresponding to the guide groove is arranged on the inner wall of the second shell.

[0012] Furthermore, a plurality of screw holes capable of penetrating the second shell body are arranged on the second shell body corresponding to the sliding buckle, and the screws are screwed to the second shell body from the outside of the screw holes.

[0013] Furthermore, the screw hole is located between the two L-shaped limiting sliders.

[0014] Furthermore, there are four slides, which are arranged on the outer wall of the first shell at equal intervals.

[0015] Furthermore, the slide grooves are symmetrically arranged on both sides of the slide platform.

[0016] Furthermore, the first shell is also provided with a plurality of screw through holes that can connect the front and rear ends of the first shell. Correspondingly, the front end cover and the rear end cover are respectively provided with front end cover connecting holes and rear end cover connecting holes corresponding to the positions of the screw through holes.

[0017] Furthermore, a heat dissipation channel capable of connecting the fan cavity with the outside is formed between the non-contact inner wall of the second shell and the first shell and the outer wall of the first shell.

[0018] The utility model provides a sleeve-type housing for a servo motor, which realizes the precise installation of the core components in the inner cavity of the first housing through a detachable front cover and a rear cover, and is encapsulated by the front cover and the rear cover; a detachable second housing is then sleeved with the first housing to complete the free construction of the dispersion cavity, so that the fan as a heat dissipation component can be independently assembled. This sleeve-type housing is not only simple in structure and easy to assemble and disassemble, but also provides a larger operating space for the installation of internal components, and can effectively improve the accuracy of component installation. While being able to effectively dissipate heat on the inner wall, it can also achieve partial heat dissipation of the outer wall of the first housing through the heat dissipation channel.

[0037] It should be noted that, in this embodiment, the first shell 1, the second shell 2, the front cover 3 and the rear cover 4 are all made of metal, preferably aluminum; wherein the first shell 1 and the second shell 2 are made of aluminum profiles.

[0038] The sleeve-type housing for the servo motor provided by this solution can not only provide a sufficiently large operating space for the installation of components in the installation cavity, but also realize the adjustment of the space of the fan cavity 6 through the sliding of the first shell 1 and the second shell 2. This separate structure can effectively improve the assembly efficiency.

[0039] like Figures 4 to 6As shown, a plurality of slides 101 are arranged on the outer wall of the first shell 1, and a plurality of slide grooves 102 are arranged on the slides 101; the inner wall of the second shell 2 matches the slides 101, and a slide buckle 201 corresponding to the slide groove 102 is arranged on the inner wall of the second shell 2, and the front end of the slide buckle 201 is slidably connected along the rear end of the slide groove 102, thereby realizing the second shell 2 being sleeved on the first shell 1.

[0040] Symmetrical limiting grooves 103 are arranged on the inner wall of the groove 102 so that the cross section of the groove 102 is cross-shaped or T-shaped. The slider 201 includes a pair of L-shaped limiting sliders 202 facing oppositely. The L-shaped limiting sliders 202 can slide with the limiting groove 103.

[0041] like Figure 4 As shown, a plurality of screw holes 204 that can penetrate the second shell 2 are provided on the second shell 2 corresponding to the sliding buckle 201, and the screws are screwed to the second shell 2 from the outside of the screw holes 204 to achieve a fastened connection between the second shell 2 and the first shell 1.

[0042] The screw hole 204 is located between the two L-shaped limit sliders 202. By tightening the screw, the two L-shaped limit sliders 202 can be squeezed outward, so that the two L-shaped limit sliders 202 are tightly fitted with the limit slide grooves 103 respectively, and finally the purpose of fastening the second shell 2 and the first shell 1 is achieved.

When the fan is working, airflow is formed in the heat dissipation channel 8, thereby achieving heat dissipation at the junction of the outer wall of the first shell 1 and the inner wall of the second shell 2. In addition, it should be noted that in this embodiment, a heat dissipation hole 701 for fan ventilation is opened on the fan cover 7.
