Description

[0001] The present application relates to the technical field of testing equipment, and in particular to a cogging force testing device and testing equipment. Background Art

[0002] The magnetic drive module is mainly composed of a coil, a permanent magnet plate, and a feedback device. The current passes through the coil to generate a traveling magnetic field, which generates an interaction force with the permanent magnet plate and then moves. The feedback device obtains the position speed and other data of the movement to the control system for control. Since the magnetic drive module has the characteristics of controllable speed and precision, in the actual production process, for areas with precise processing requirements, a high-speed and high-precision conveying system such as a magnetic drive module is usually used. In the magnetic drive module, due to the presence of the permanent magnet plate and the coil, there is a cogging force between the permanent magnet plate and the coil. When the mover moves on the magnetic drive line, the permanent magnet plate of the mover will be subject to a large cogging force resistance.

[0038] The technical solution provided by the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0039] See also Figure 1 and Figure 2 As shown, the present application provides a cogging force testing device 100, which can be configured in a magnetic drive module 200, the magnetic drive module 200 includes a line body 210 and a mover 220 to be tested, the mover 220 to be tested is slidably arranged on the line body 210, and during the sliding of the mover 220 to be tested on the line body 210, the permanent magnet plate of the mover 220 to be tested will be subjected to a large cogging force resistance. The cogging force testing device 100 includes a driving member 110, a transmission assembly 120 and a dynamometer 130, which is used to test the cogging force of the mover 220 to be tested.

[0040] The driving member 110 is connected to the dynamometer 130 through the transmission assembly 120. One of the driving member 110 and the dynamometer 130 is detachably arranged on the movable member 220 to be measured, and the other is detachably fixed to the line body 210. That is, if the driving member 110 is arranged on the movable member 220 to be measured, the dynamometer 130 is fixed to the line body 210; if the driving member 110 is fixed to the line body 210, the dynamometer 130 is arranged on the movable member 220 to be measured. The driving member 110 is used to push the movable member 220 to be measured to slide relative to the line body 210, and the dynamometer 130 is used to measure the cogging force of the movable member 220 to be measured during the movement. Specifically, when it is necessary to test the cogging force of the movable member 220 to be tested during the sliding process of the wire body 210, one of the driving member 110 and the dynamometer 130 is set on the movable member 220 to be tested, and the other is fixed to the wire body 210. The driving member 110 outputs power to the dynamometer 130 through the transmission assembly 120 to push the movable member 220 to be tested to slide relative to the wire body 210, and during the sliding process of the movable member 220 to be tested, the dynamometer 130 can measure the cogging force of the movable member 220 to be tested during the movement.

[0041] It should be noted that when the driving member 110 outputs power, the measured mover 220 will move with a tendency of first accelerating and then uniform speed. Since the magnitude of the power output of the driving member 110 measured by the dynamometer 130 is consistent with the magnitude of the cogging force received by the measured mover 220 during the uniform speed motion of the measured mover 220, the measured mover 220 is based on the magnitude of the cogging force fed back by the dynamometer 130 during the uniform speed motion stage. In this embodiment, the driving member 110 is one of a driving motor and a driving cylinder, and the dynamometer 130 is a push-pull dynamometer. Of course, in other feasible embodiments, the driving member 110 can also be a hydraulic cylinder or other element capable of outputting power, and the dynamometer 130 can also be a pressure sensor or other element capable of measuring force. The specific element types of the driving member 110 and the dynamometer 130 are not limited by this application.

[0042] The cogging force testing device 100 can automatically measure the cogging force of the tested mover 220 during the sliding process of the wire body 210 without being affected by manual operation errors, thereby improving the cogging force testing accuracy during the movement of the tested mover 220.

[0043] Further, see Figure 1 and Figure 2 As shown, the cogging force testing device 100 further includes an adapter plate 140. The adapter plate 140 is arranged on the dynamometer 130 by screwing, riveting, etc., and the adapter plate 140 is transmission-connected with the transmission assembly 120 to transmit the power output by the driving member 110 to the dynamometer 130. Since the dynamometer 130 is arranged on the mover 220 to be tested or fixed on the line body 210, and the driving member 110 is correspondingly fixed on the line body 210 or arranged on the mover 220 to be tested, under the condition of action force or reaction force, the dynamometer 130 can apply the power output by the driving member 110 to the mover 220 to be tested, so as to push the mover 220 to be tested to slide relative to the line body 210, and then the dynamometer 130 can test the cogging force of the mover 220 to be tested during the movement.

[0044] In one embodiment, refer to Figure 1 and Figure 2As shown, the adapter plate 140 is provided with a plug hole 141, and the plug hole 141 penetrates the adapter plate 140 in the thickness direction of the adapter plate 140. Preferably, the plug hole 141 is integrally formed on the adapter plate 140 by injection molding, extrusion, etc., so as to simplify the molding process of opening the plug hole 141 on the adapter plate 140. The transmission assembly 120 includes a screw rod 121 and a nut 122, the nut 122 is fixed to the adapter plate 140 by welding, etc., and the nut 122 is coaxially arranged with the plug hole 141, the screw rod 121 is inserted into the plug hole 141, and the screw rod 121 and the nut 122 are threadedly matched, one end of the screw rod 121 is connected to the output end of the driving member 110, and the other end of the screw rod 121 extends to the side of the adapter plate 140 away from the driving member 110. When the driving member 110 outputs power to the screw rod 121, since the screw rod 121 is threadedly matched with the nut 122, while the screw rod 121 rotates in the nut 122, the screw rod 121 can push the movable member 220 to be tested to make reciprocating linear motion along the line body 210, so as to push the movable member 220 to be tested to slide relative to the line body 210, and then the dynamometer 130 can test the size of the tooth groove force of the movable member 220 to be tested during the movement.

[0045] In another embodiment, see Figure 2 and Figure 3 As shown, the adapter plate 140 is provided with a plug hole 141, and the plug hole 141 penetrates the adapter plate 140 in the thickness direction of the adapter plate 140. Preferably, the plug hole 141 is integrally formed on the adapter plate 140 by injection molding, extrusion, etc., so as to simplify the molding process of opening the plug hole 141 on the adapter plate 140. The transmission assembly 120 includes a screw rod 121, and the screw rod 121 is screwed with the plug hole 141. For example, an internal thread is provided on the inner wall forming the plug hole 141, and the screw rod 121 is screwed with the internal thread to realize the screw connection between the screw rod 121 and the plug hole 141. One end of the screw rod 121 is connected to the output end of the driving member 110, and the other end of the screw rod 121 extends to the side of the adapter plate 140 away from the driving member 110. When the driving member 110 outputs power to the screw rod 121, since the screw rod 121 is threadedly matched with the plug-in hole 141, while the screw rod 121 rotates in the plug-in hole 141, the screw rod 121 can push the movable member 220 to be tested to make reciprocating linear motion along the line body 210, so as to push the movable member 220 to be tested to slide relative to the line body 210, and then the dynamometer 130 can test the size of the tooth groove force of the movable member 220 to be tested during the movement.

[0046] In one embodiment, refer to Figure 1 and Figure 2As shown, the magnetic drive module 200 further includes a fixed mover 230, which is fixed to the wire body 210, and the mover 220 to be measured can move in a direction close to or away from the fixed mover 230. Exemplarily, the fixed mover 230 is fixed relative to the wire body 210, and the mover 220 to be measured can slide back and forth on the wire body 210 to move in a direction close to or away from the fixed mover 230. The driving member 110 is detachably arranged on the fixed mover 230 by screwing, riveting, etc., and the dynamometer 130 is arranged on the mover 220 to be measured by screwing, riveting, etc., so that when the driving member 110 outputs power to the dynamometer 130, the dynamometer 130 can transmit power to the mover 220 to be measured, so that the mover 220 to be measured moves in a direction close to or away from the fixed mover 230. The driving member 110 can be detachably arranged on the fixed mover 230, and the dynamometer 130 can be detachably arranged on the mover 220 to be tested, so that when it is necessary to test the cogging force of the mover 220 to be tested, the driving member 110 and the dynamometer 130 can be respectively arranged on the fixed mover 230 and the mover 220 to be tested, and after the cogging force test of the mover 220 to be tested is completed, the connection between the driving member 110 and the fixed mover 230 can be released, and the connection between the dynamometer 130 and the mover 220 to be tested can be released, so as to avoid the adverse effect of the cogging force testing device 100 on the movement of the mover 220 to be tested.

[0047] In one embodiment, refer to Figure 1 and Figure 2 As shown, the cogging force testing device 100 further includes a first fixing seat 150 and a second fixing seat 160. One of the first fixing seat 150 and the second fixing seat 160 is detachably disposed on the movable member 220 to be tested, and the other of the first fixing seat 150 and the second fixing seat 160 is detachably fixed to the wire body 210, that is, if the first fixing seat 150 is disposed on the movable member 220 to be tested, the second fixing seat 160 is fixed to the wire body 210; if the first fixing seat 150 is fixed to the wire body 210, the second fixing seat 160 is disposed on the movable member 220 to be tested. The driving member 110 is disposed on the first fixing seat 150, such as the driving member 110 is disposed on the first fixing seat 150 through the fixing plate 170, and the dynamometer 130 is disposed on the second fixing seat 160, so that the driving member 110 and the dynamometer 130 are respectively disposed on the movable member 220 to be tested or the wire body 210.

[0048] Further, see Figure 1 and Figure 2As shown, the driving member 110 is detachably arranged on the first fixing seat 150 by means of screw connection, riveting, etc., so that when the driving member 110 fails or needs to be replaced with a driving member 110 of suitable power, it is only necessary to remove the driving member 110 from the first fixing seat 150 and replace the driving member 110, without scrapping the entire cogging force testing device 100, which can reduce the testing cost of the mover 220 to be tested. Similarly, the dynamometer 130 is detachably arranged on the second fixing seat 160 by means of screw connection, riveting, etc., so that when the dynamometer 130 fails or needs to be replaced with a dynamometer 130 of suitable force range, it is only necessary to remove the dynamometer 130 from the second fixing seat 160 and replace the dynamometer 130, without scrapping the entire cogging force testing device 100, which can further reduce the testing cost of the mover 220 to be tested.

[0049] In one embodiment, refer to Figure 1 and Figure 2 As shown, the cogging force testing device 100 also includes a display terminal (not shown in the figure), which is connected to the dynamometer 130 for communication. For example, the display terminal is connected to the dynamometer 130 for communication via WIFI, Bluetooth, etc., so that when the dynamometer 130 measures the cogging force of the mover 220 to be tested during movement, the dynamometer 130 can feed back the cogging force to the display terminal, and provide visual feedback to the operating user through the display terminal.

[0050] The display terminal may be a computer terminal, a display screen terminal or other element that can provide visual feedback on the size of the cogging force. The present application does not limit the specific element type of the display terminal.

[0051] Also, see Figure 1 , Figure 2 and Figure 4 As shown, the present application also provides a test device 300, which includes a magnetic drive module 200 and a cogging force test device 100 as described in the above technical solution. The magnetic drive module 200 includes a wire body 210, a coil stator 240 and a mover 220 to be tested, the coil stator 240 is arranged on the wire body 210, and the mover 220 to be tested is slidably arranged on the wire body 210. Due to the existence of the coil mover, when the mover 220 to be tested slides on the wire body 210, the permanent magnet plate of the mover 220 to be tested will be subjected to a large cogging force resistance. The cogging force test device 100 is detachably arranged on the wire body 210, and is used to test the cogging force of the mover 220 to be tested.

[0052] The above-mentioned test equipment 300, when it is necessary to test the cogging force of the movable member 220 to be tested during the sliding process of the wire body 210, one of the driving member 110 and the dynamometer 130 is set on the movable member 220 to be tested, and the other is fixed to the wire body 210, and the driving member 110 outputs power to the dynamometer 130 through the transmission assembly 120 to push the movable member 220 to be tested to slide relative to the wire body 210, and during the sliding process of the movable member 220 to be tested, the dynamometer 130 can measure the cogging force of the movable member 220 to be tested during the movement. The test equipment 300 provided in the present application can automatically measure the cogging force of the movable member 220 to be tested during the sliding process of the wire body 210, and is not affected by manual operation errors, so as to improve the cogging force test accuracy during the movement of the movable member 220 to be tested.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
