Technical Field

[0001] The utility model belongs to the technical field of handwheel pulse generators, and particularly relates to a handwheel pulse generator with a teaching function. Background Art

[0002] A handwheel pulse generator, also known as a manual pulse generator, an electronic handwheel or a hand-operated pulse generator, is a manually operated generator that can generate pulse signals. As a precision human-computer interaction device, the handwheel pulse generator is mainly used for precise control of position and speed in numerical control machine tools and automation equipment. It is a device that generates pulse signals by rotating the handwheel, and its principle is based on the opening and closing of contacts, and uses mechanical transmission and circuit design to convert the opening and closing of contacts into high and low level outputs of electrical signals.

[0003] However, in the use of existing handwheel pulse generators, the phenomenon that the user accidentally touches the handwheel easily occurs, which affects the normal operation of the handwheel pulse generator and poses a certain safety hazard. Summary of the Utility Model

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment, as Figure 1 - Figure 5 As shown, a handwheel pulse generator with a teaching function includes a pulse generator main body 1, a handwheel 11, a handle mechanism 12, a limiting mechanism 13, a cable 14 and a teach pendant 15. The cable 14 is installed at the bottom of the pulse generator main body 1; the teach pendant 15 is installed on the front of the pulse generator main body 1. The handwheel 11 is rotatably installed on the front of the pulse generator main body 1. The handle mechanism 12 includes a fixed seat 121, a handle rod 122 and an engaging tooth head 123. The fixed seat 121 is fixedly installed on the handwheel 11; the handle rod 122 is hinged to the fixed seat 121; the engaging tooth head 123 is installed at one end of the handle rod 122 away from the fixed seat 121. The limiting mechanism 13 includes an internal gear ring 131, and the internal gear ring 131 is installed on the front of the pulse generator main body 1, and the engaging tooth head 123 is engaged with the internal gear ring 131.

[0024] Specifically, when it is necessary to rotate the handwheel 11, by rotating the handle rod 122, the engaging tooth head 123 is separated from the internal gear ring 131, so that the handle rod 122 is perpendicular to the handwheel 11, and then, by rotating the handle rod 122, the handwheel 11 is driven to rotate.

[0025] When it is not necessary to rotate the handwheel 11, by rotating the handle rod 122, the engaging tooth head 123 is engaged with the teeth on the internal gear ring 131, so that the handwheel 11 cannot be rotated, thereby avoiding the phenomenon that the user accidentally rotates the handwheel 11.

[0026] The handwheel pulse generator in this device, in combination with the structure of the teach pendant 15, fills the gap in the current market where the functions cannot be realized when dealing with relatively complex mechanical equipment. While maintaining high stability, it expands the user's selection range for the handwheel pulse generator. Through precise control of 13 signals (axis selection: X, Y, Z, 4, 5, 6, 7, 8) (speed gear: OFF, ×1, ×10, ×100) (button: teach) by 6 groups of signal lines (A0, A1, A2, B0, B1, B2), it reduces the number of signals received by the control system, reduces the design space occupancy ratio of large equipment, and reduces costs.

[0027] As Figure 1 - Figure 5 Shown in the figure, the limit mechanism 13 further includes an airbag ring 132. The airbag ring 132 is installed on the front surface of the internal gear ring 131, and the airbag ring 132 protrudes from the internal gear ring 131. The handwheel 11 pulse generator with a teach function further includes two first buffer members 16 and four second buffer members 17. The two first buffer members 16 are both installed on the front surface of the pulse generator main body 1; the four second buffer members 17 are both installed on the back surface of the pulse generator main body 1.

[0028] The first buffer member 16 includes a fixed column 161, a movable cylinder 162, and a spring 163. The fixed column 161 is installed on the front surface of the pulse generator main body 1; the movable cylinder 162 is slidably sleeved on the fixed column 161; the movable cylinder 162 is made of rubber, the fixed column 161 is made of plastic, one end of the spring 163 is connected to the fixed column 161, the other end of the spring 163 is connected to the movable cylinder 162, and the spring 163 is made of stainless steel. The second buffer member 17 has the same structure as the first buffer member 16. The difference between the second buffer member 17 and the first buffer member 16 is that the length of the second buffer member 17 is less than that of the first buffer member 16.

[0029] Working principle: During specific use, when it is necessary to rotate the handwheel 11, by rotating the handle rod 122, the engaging tooth head 123 is separated from the internal gear ring 131, making the handle rod 122 perpendicular to the handwheel 11. Then, by rotating the handle rod 122, the handwheel 11 is driven to rotate.

[0030] When it is not necessary to rotate the handwheel 11, by rotating the handle rod 122, the engaging tooth head 123 is engaged with the teeth on the internal gear ring 131, making the handwheel 11 unable to be rotated, thus avoiding the phenomenon that the user accidentally rotates the handwheel 11.

[0031] When the device accidentally drops, if the side close to the handwheel 11 touches the ground first, the airbag ring 132 and the movable cylinder 162 on the first buffer member 16 will contact the ground first. The movable cylinder 162 will compress the spring 163, and the resilience of the spring 163 can provide buffering for the fixed column 161. The elasticity of the airbag ring 132 can provide buffering for the internal gear ring 131, so as to provide buffering for the pulse generator main body 1, thereby preventing the pulse generator main body 1 from being damaged.

[0032] When the device accidentally drops, if the side far from the handwheel 11 touches the ground first, the four second buffer members 17 will provide buffering for the pulse generator main body 1, thereby preventing the pulse generator main body 1 from being damaged.

[0033] As mentioned above, it is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific embodiments.
