Description

Technical Field

[0001] The utility model relates to the field of motors, in particular to an anti-collision protection structure for a motor. Background Art

[0002] In some mechanical structures, slides are often needed for transmission. In some cross slides, two slides are distributed in a cross shape, and one slide can move above the other slide. When working, it is generally necessary to equip the lower slide with corresponding anti-collision devices at the extreme positions on both sides of the motor. When the motor of the slide fails and causes the upper slide to move beyond the maximum stroke, the impact can be buffered and anti-collision. The traditional method is generally to provide rubber columns or spring shock absorbers at the extreme positions on both sides. Due to the small contact area, the impact on the upper slide is concentrated in a part of the area, resulting in a large impact. This anti-collision measure will still generate vibration force during the collision, so it is easy to cause vibration to the mover and stator in the motor. For this reason, we designed a motor anti-collision protection structure. Utility Model Content

[0003] In order to solve the technical problem that vibration force is still generated during collision, which easily causes vibration influence on the mover and stator in the motor, the utility model provides an anti-collision protection structure for the motor.

[0004] The utility model is implemented by the following technical scheme: a motor anti-collision protection structure, including a slide table one, a slide table two is installed on the slider of the slide table one, a mounting plate one is fixed to the left and right ends of the upper side of the slide table one by screws, a contact rubber pad is arranged on the inner side of the mounting plate one, and two symmetrically distributed spring shock absorbers are installed on the outward end of each mounting plate one, the push rods of the spring shock absorbers pass through the contact rubber pad and are placed on the inner side thereof, mounting plates two are installed on the left and right side surfaces of the slide table two, and impact rubber pads are installed on the outward side of the mounting plate two, and the position of the impact rubber pad corresponds to the position of the contact rubber pad.

[0005] As a further improvement of the above scheme, symmetrically distributed mounting holes are provided at the front and rear ends of the mounting plate one, and the mounting holes extend inwardly through the contact rubber pad. The spring shock absorber is installed on the mounting plate one, and the inward end of the push rod of the spring shock absorber passes through the mounting hole and is placed on the inner side of the contact rubber pad, which is convenient for the installation and disassembly of the spring shock absorber. The spring shock absorber can further buffer the upper slide table two, thereby avoiding the influence of excessive vibration on the two motors.

[0006] As a further improvement of the above scheme, recessed holes are provided at both front and rear ends of the outward side of the impact rubber pad, and the axis of the recessed hole is colinear with the axis of the spring shock absorber. The depth of the recessed hole is greater than the length of the push rod of the spring shock absorber outside the contact rubber pad. The inward end of the spring shock absorber can extend into the recessed hole, so that the impact rubber pad first contacts and buffers with the contact rubber pad, and then the spring shock absorber contacts and buffers it for the second time, thereby reducing the impact between the spring shock absorber and the contact rubber pad.

[0007] As a further improvement of the above scheme, the lower end opening of the contact rubber pad is designed to form an installation notch, and the lower end opening of the impact rubber pad is designed to form a moving notch, and the installation notch and the moving notch are both located on the screw of slide one, which facilitates the installation and disassembly of the contact rubber pad and the impact rubber pad.

[0008] As a further improvement of the above scheme, the mounting notch at the lower end of the contact rubber pad is placed just in front of the bearing seat of slide table one, the inward end of the contact rubber pad is 3-5 cm away from the inward side of the bearing seat, the size of the mounting notch is larger than the size of the bearing seat, the mounting notch is consistent with the shape and size of the moving notch, and the contact rubber pad has a certain thickness, which enables a certain degree of deformation buffering when contact is made.

[0009] As a further improvement of the above scheme, switch seats are provided on the front sides of the left and right ends of the slide one, and a switch button is installed on the inner end of the switch seat, the switch button is aligned with the push rod of the spring shock absorber, and the two switch buttons are connected in series with the motor in the slide one, the push rod of the spring shock absorber can press the switch button, thereby disconnecting the power supply of the motor and stopping it from running.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model provides impact rubber pads on the left and right sides of the slide table 1, and contact rubber pads on the left and right sides above the slide table 1. The two have good elasticity, so that the impact rubber pads and the contact rubber pads are deformed accordingly during collision, and the overall contact area of ​​the impact rubber pads and the contact rubber pads is also increased, so that the energy is dispersed over a larger area, thereby generating a smaller impact force and further reducing the impact force generated during collision;

[0012] 2. By arranging spring shock absorbers at the left and right ends of the contact rubber, the spring shock absorbers can contact and buffer the impact rubber pad only after the impact rubber pad and the contact rubber pad are in overall contact and buffering, which can further buffer the upper slide table 2, avoiding the impact of excessive vibration on the two motors, and can disconnect the power supply of the motor to stop it from running, and also avoid damage to the switch button caused by excessive movement force.

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0020] Example:

[0021] Please combine Figure 1-Figure 4 A motor anti-collision protection structure of the present embodiment includes a slide 1, a slide 2 is installed on the slider of the slide 1, a mounting plate 3 is fixed to the left and right ends of the slide 1 by screws, a contact rubber pad 4 is arranged on the inner side of the mounting plate 3, and two symmetrically distributed spring shock absorbers 5 are installed on the outward end of each mounting plate 3, and the push rod of the spring shock absorber 5 passes through the contact rubber pad 4 and is placed on the inner side thereof, mounting plates 2 8 are installed on the left and right side surfaces of the slide 2, and impact rubber pads 7 are installed on the outward side of the mounting plates 2 8, and the position of the impact rubber pad 7 corresponds to the position of the contact rubber pad 4.

[0022] Symmetrically distributed mounting holes 31 are provided at the front and rear ends of the mounting plate 3, and the mounting holes 31 extend inwardly through the contact rubber pad 4. The spring shock absorber 5 is installed on the mounting plate 3, and the inward end of the push rod of the spring shock absorber 5 passes through the mounting hole 31 and is placed on the inner side of the contact rubber pad 4, which is convenient for the installation and disassembly of the spring shock absorber 5. The spring shock absorber 5 can further buffer the upper slide 2 to avoid the influence of excessive vibration on the two motors.

[0023] The impact rubber pad 7 is provided with concave holes 71 at both the front and rear ends of the outward side, and the axis of the concave hole 71 is colinear with the axis of the spring shock absorber 5. The depth of the concave hole 71 is greater than the length of the push rod of the spring shock absorber 5 outside the contact rubber pad 4. The inward end of the spring shock absorber 5 can extend into the concave hole 71, so that the impact rubber pad 7 first contacts and buffers with the contact rubber pad 4, and then the spring shock absorber 5 contacts and performs secondary buffering, thereby reducing the impact between the spring shock absorber 5 and it.

[0024] The lower end opening of the contact rubber pad 4 is designed to form an installation notch 41, and the lower end opening of the impact rubber pad 7 is designed to form a moving notch 72. The installation notch 41 and the moving notch 72 are both located on the lead screw of the slide 1, which is convenient for the installation and disassembly of the contact rubber pad 4 and the impact rubber pad 7.

[0025] The mounting notch 41 at the lower end of the contact rubber pad 4 is placed just in front of the bearing seat 11 of the slide 1. The inward end of the contact rubber pad 4 is 3-5 cm away from the inward side of the bearing seat 11. The size of the mounting notch 41 is larger than the size of the bearing seat 11. The mounting notch 41 is consistent in shape and size with the moving notch 72. The contact rubber pad 4 has a certain thickness, which enables a certain degree of deformation buffering when making contact.

[0026] A switch seat 6 is provided on the front sides of both left and right ends of the slide 1, and a switch button 61 is installed on the inner end of the switch seat 6. The switch button 61 is aligned with the push rod of the spring shock absorber 5, and the two switch buttons 61 are connected in series with the motor in the slide 1. The push rod of the spring shock absorber 5 can press the switch button 61, thereby disconnecting the power supply of the motor and stopping it from running.

[0027] The implementation principle of a motor anti-collision protection structure in the embodiment of the present application is as follows: in actual use, when the upper slide 2 fails during the left-right movement and moves to the outside of the maximum stroke, the impact rubber pad 7 at this time will first contact the contact rubber pad 4. Since both are soft rubber pads with good elasticity, the slide 2 will cause the impact rubber pad 7 and the contact rubber pad 4 to deform accordingly during the movement of the slide 2, and reduce the impact force generated during the collision. Then, the mounting plate 2 8 will contact the spring shock absorber 5 and cause the push rod of the spring shock absorber 5 to move outward until it contacts the switch button 61, thereby disconnecting the power supply of the motor and stopping it from running.

[0028] By arranging the impact rubber pads 7 on the left and right sides of the slide 1 and the contact rubber pads 4 on the left and right sides above the slide 1, the two have good elasticity, so that the impact rubber pads 7 and the contact rubber pads 4 are deformed accordingly during collision, and the overall contact area of ​​the impact rubber pads 7 and the contact rubber pads 4 is also increased, so that the energy is dispersed over a larger area, thereby generating a smaller impact force and further reducing the impact force generated during the collision;

[0029] By arranging spring shock absorbers 5 at the left and right ends of the contact rubber, the spring shock absorbers 5 can contact and buffer the impact rubber pad 7 only after the impact rubber pad 7 and the contact rubber pad 4 are in overall contact and buffering, which can further buffer the upper slide 2, avoiding the influence of excessive vibration on the two motors, and can disconnect the power supply of the motor to stop it from running, and also avoid damage to the switch button 61 caused by excessive movement force.

[0030] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
