Typical grinding devices include a clamping mechanism for holding the connector housing, a grinding mechanism, and a drive mechanism for driving the clamping mechanism's multi-axis motion and the grinding mechanism's operation. Such grinding devices are complex in structure and expensive to produce. Furthermore, the contact area between the clamping mechanism and the connector housing is limited, and the connector housing may shift during grinding, affecting the polishing quality. Utility Model Content

[0003] In order to address the above-mentioned deficiencies in the prior art, the present application provides a connector housing polishing device, which has a relatively simple structure, lower production cost, and better polishing quality.

[0004] In order to achieve the above purpose, the utility model adopts the following technologies:

[0005] A connector housing polishing device, comprising:

[0007] The grinding mechanism includes a first transmission shaft and a pulley coaxially mounted in the middle of the driving shaft, and a grinding belt is sleeved on the two pulleys;

[0008] The clamping mechanism is arranged on one side of the grinding belt and includes two clamping blocks arranged opposite to each other. The clamping blocks are respectively connected to one end of the corresponding second transmission shaft. The distance between the two clamping blocks is adjustable, and the shape of the clamping blocks is adapted to the shape of the pin seat in the connector housing.

[0009] Furthermore, one of the second transmission shafts is a movable shaft, that is, it is arranged to move along its own axis, and the other second transmission shaft is a fixed shaft, that is, it cannot move along its own axis; plug-in holes are opened on the opposite surfaces of the two clamping blocks along the axis direction of the second transmission shaft, which are used to plug in the two ends of the pin seat inside the connector housing.

[0010] Furthermore, a guide seat is coaxially provided at the other end of the movable shaft, and the guide seat is rotatably arranged around its own axis. A mounting hole is provided on the guide seat along the axis direction of the second transmission shaft, and the inner wall of the mounting hole is provided with at least one guide bar arranged along the axis direction of the second transmission shaft; a guide groove is provided on the movable shaft along its own axis, and the movable shaft is passed through the mounting hole of the guide seat through the cooperation of the guide bar and the guide groove; a spring is sleeved on the movable shaft, and the spring is connected between the guide seat and the clamping block.

[0014] 1. The driving shaft drives the pulley in the grinding mechanism to rotate, thereby driving the grinding belt to run. At the same time, under the action of the reduction gear group, the force of the driving shaft is transmitted to the second transmission shaft, causing the second transmission shaft to rotate around its own axis, thereby driving the two clamping blocks to rotate, and the rotation speed of the clamping blocks is lower than the rotation speed of the driving shaft, that is, a speed difference is formed between the connector housing clamped by the clamping blocks and the grinding belt, thereby realizing the function of grinding the edges of the connector housing while the grinding belt rotates.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] The embodiment of the present application provides a connector housing polishing device, such as Figure 1 As shown, it includes: a transmission mechanism 1, a base 2, a grinding mechanism 3, a clamping mechanism 4, and a collecting mechanism 6.

[0024] Among them, the transmission mechanism 1 includes a first transmission shaft 11 and a drive shaft 12 arranged along the height direction of the base 2 and parallel to each other, one end of the drive shaft 12 is coaxially connected to the drive end of a drive motor 15, and the transmission mechanism 1 also includes a pair of second transmission shafts 13 arranged between the first transmission shaft 11 and the drive shaft 12, the first transmission shaft 11, the drive shaft 12, and the second transmission shaft 13 are all arranged to rotate around their own axes, the two second transmission shafts 13 are parallel to the first transmission shaft 11, and the two second transmission shafts 13 are coaxially arranged opposite to each other. The second transmission shaft 13 is spaced a predetermined distance from the plane where the first transmission shaft 11 and the drive shaft 12 are located, that is, when the second transmission shaft 13 rotates, the edge of the connector housing clamped by the clamping block 41 can contact the grinding belt 32; the ends of the drive shaft 12 and the second transmission shaft 13 are provided with reduction gears The wheel set 14 is used to transmit power between the drive shaft 12 and the second transmission shaft 13 so that the rotation speed of the second transmission shaft 13 is less than the rotation speed of the drive shaft 12; the grinding mechanism 3 includes a pulley 31 coaxially installed in the middle of the first transmission shaft 11 and the drive shaft 12, and a grinding belt 32 is provided on the two pulleys 31; the two clamping blocks 41 in the clamping mechanism 4 are respectively connected to one end of the corresponding second transmission shaft 13, and the distance between the two clamping blocks 41 is adjustable. The shape of the clamping block 41 is adapted to the shape of the pin seat 51 in the connector housing 5; the collecting mechanism 6 is installed on the base 2 and is used to collect debris generated during grinding.

[0025] When in use, first adjust the distance between the two clamping blocks 41 so that the two clamping blocks 41 respectively rest on both sides of the pin seat 51 inside the connector housing 5, thereby fixing the connector housing 5. At this time, the central axis of the connector housing 5 is coaxial with the axis of the second transmission shaft 13; the driving motor 15 drives the driving shaft 12 to rotate, and the pulley 31 on the driving shaft 12 rotates accordingly, thereby driving the grinding belt 32 to run; after the driving shaft 12 rotates, the reduction gear set 14 transmits the force of the driving shaft 12 to the second transmission shaft 13, and makes the rotation speed of the second transmission shaft 13 lower than the rotation speed of the driving shaft 12. At this time, the connector housing 5 clamped by the clamping blocks 41 rotates with the axis of the second transmission shaft 13 as the rotation center, and its edges turn to the grinding belt 32 in turn. At the same time, since the pulley 31 has a higher rotation speed than the second transmission shaft 13, a speed difference is formed between the connector housing 5 and the grinding belt 32, so that each time the edges of the connector housing 5 turn to the grinding belt 32 and contact it, the grinding belt 32 can grind the edges once. By using a drive motor 15 as a power source and cooperating with the transmission mechanism 1, not only the driving of the grinding belt 32 is achieved, but also the adjustment of the grinding position of the connector shell 5 is achieved. The function of grinding the burrs on the edges of the connector shell 5 is achieved with a relatively simple structure, and the production cost of the device is reduced.

[0026] Specifically, such as Figures 1 to 3As shown, one of the second transmission shafts 13 is a movable shaft 131, that is, it is set to move along its own axis, and the other second transmission shaft 13 is a fixed shaft 132, that is, it cannot move along its own axis; the two clamping blocks 41 have opposite surfaces along the axis direction of the second transmission shaft 13. Connecting holes 411 are opened for connecting with the pin seats 51 inside the two sides of the connector housing 5. During application, the two ends of the pin seat 51 inside the connector housing 5 are respectively inserted into the corresponding plug-in holes 411 of the clamping block 41, so as to clamp and fix the connector housing 5. Since the cross-section of the end of the pin seat 51 inside the connector housing 5 is rectangular, the plug-in hole 411 is a rectangular hole adapted to the end of the pin seat 51. Through the cooperation between the end of the pin seat 51 and the plug-in hole 411, the connector housing 5 can be effectively limited to avoid displacement during polishing, so that the polishing effect is better. At the same time, the connector housing 5 acts as a coupling between the movable shaft 131 and the fixed shaft 132, so that when clamped, the movable shaft 131 can rotate together with the fixed shaft 132, further optimizing the structure of the device.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, a guide seat 42 is coaxially provided at the other end of the movable shaft 131, and the guide seat 42 is rotatably arranged around its own axis. A mounting hole 421 is provided on the guide seat 42 along the axial direction of the second transmission shaft 13, and the inner wall of the mounting hole 421 is provided with at least one guide bar 422 arranged along the axial direction of the second transmission shaft 13; a guide groove 133 is provided on the movable shaft 131 and is arranged along its own axis and is the same in number as the guide bars 422, and the movable shaft 131 is passed through the mounting hole 421 of the guide seat 42 through the cooperation between the guide bars 422 and the guide grooves 133; a spring 43 is sleeved on the movable shaft 131, and the spring 43 is connected between the guide seat 42 and the clamping block 41. By cooperating with the guide bar 422 and the guide slot 133, the guide seat 42 can rotate along with the movable shaft 131 when the movable shaft 131 rotates. That is, when the device is in operation, the spring 43 remains stationary relative to the movable shaft 131 and the guide seat 42, eliminating the effect of the rotation of the movable shaft 131 and the guide seat 42 on the spring 43. The spring 43 can continuously provide a clamping force to the clamping block 41. When removing the connector housing 5, it is only necessary to pull the clamping block 41 connected to the movable shaft 131 from one end of the pin seat 51, and then pull the connector housing 5 from the other clamping block 41. The above operation is reversed during installation. The above structural design simplifies the installation and removal of the connector housing 5, improves the convenience of device operation, and at the same time, the provision of the spring 43 ensures that the two clamping blocks 41 clamp the connector housing 5, thereby improving the reliability of the device.

[0028] Specifically, such as Figure 1 and Figure 4As shown, the reduction gear set 14 includes a driving gear 141 mounted on one end of the drive shaft 12 and an output gear 142 mounted on one end of the fixed shaft 132. The driving gear 141 is directly or indirectly meshed with the output gear 142. The number of teeth of the driving gear 141 is smaller than that of the output gear 142. The rotational speed of the output gear 142 should be lower than that of the driving gear 141, that is, the number of teeth of the output gear 142 should be greater than that of the driving gear 141. Accordingly, when an intermediate gear is present between the output gear 142 and the driving gear 141, the number of teeth of the intermediate gear should also meet the speed difference requirement between the output gear 142 and the driving gear 141.

[0029] In order to prevent the debris generated during the operation of the device from being inhaled by the operator and affecting his health, this embodiment proposes a preferred solution, which is as follows: Figure 1 、 Figure 4 、 Figure 5 As shown, the base 2 is provided with a mounting slot 21, and a vent 22 is provided at the bottom of the mounting slot 21. An exhaust fan 61 in the collection mechanism 6 is located within the vent 22. A collection tray 62 is removably mounted within the mounting slot 21. The collection tray 62 is provided with vent holes 63, which are smaller than the size of the debris. The exhaust fan 61 is used to exhaust air between the collection tray 62 and the bottom of the mounting slot 21. During operation, the exhaust fan 61 exhausts air between the collection tray 62 and the bottom of the mounting slot 21, creating a negative pressure below the collection tray 62, thereby attracting debris generated during grinding onto the collection tray 62, effectively preventing the debris from flying and being inhaled by the operator.

[0030] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
