Description

Technical Field

[0001] This utility model relates to the field of gear grinding machine technology, specifically to a grinding wheel shaft locking structure and a vertical gear grinding machine. Background Technology

[0002] Gear grinding machines are gear processing machine tools that use grinding wheels as abrasives to process cylindrical gears or certain gears (helical gears, bevel gears, etc.) and the tooth surfaces of cutting tools. They are mainly used to eliminate deformation after heat treatment and improve gear accuracy.

[0003] Existing gear grinding machines are designed with a grinding wheel shaft locking structure to fix the grinding wheel shaft. The grinding wheel shaft locking structure has two positioning sensors. The two positioning sensors identify the axial position and the angle after rotation of the grinding wheel shaft to confirm whether the grinding wheel shaft is installed in place. The design of multiple sensors makes the equipment cost high.

[0004] Therefore, it is necessary to provide a new grinding wheel shaft locking structure and a vertical gear grinding machine. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the purpose of this utility model embodiment is to provide a grinding wheel shaft locking structure that can reduce the cost of the equipment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A grinding wheel shaft locking structure is provided, comprising a grinding wheel frame, a grinding wheel shaft, a grinding wheel, a connecting seat, a locking plate, a sensor, and a positioning block. The grinding wheel is rotatably fitted onto the grinding wheel frame via the grinding wheel shaft. The first end of the grinding wheel shaft is mounted on the grinding wheel frame, and the second end of the grinding wheel shaft is detachably connected to the connecting seat. The connecting seat is slidably fitted onto the grinding wheel frame along the axial direction of the grinding wheel shaft. The locking plate is rotatably fitted onto the connecting seat. By rotating the locking plate on the connecting seat, the connecting seat can be locked onto the grinding wheel frame. The sensor is mounted on the locking plate. The connecting seat is provided with a positioning block opposite to the sensor. The positioning block has a low surface and a high surface distributed along the rotation path of the locking plate. When the connecting seat slides close to the grinding wheel on the grinding wheel frame, the sensor aligns with the low surface of the positioning block. When the connecting seat slides close to the grinding wheel and the locking plate rotates to its position on the connecting seat, the sensor contacts the high surface of the positioning block, thereby triggering the sensor's position sensing.

[0007] Furthermore, the connecting seat is provided with a guide rod, which is inserted into and slidably engaged with the grinding wheel frame.

[0008] Furthermore, the locking plate has a ring-shaped structure.

[0009] Furthermore, the locking plate is provided with a fixing arm on its side, and a slot is provided on the fixing arm. A stud is provided on the grinding wheel frame, and the end of the stud is provided with a stud end protruding radially around the stud. When the locking plate rotates, it drives the fixing arm to rotate until the slot fits onto the stud, and at the same time, the stud end is located on the side of the fixing arm away from the grinding wheel shaft.

[0010] Furthermore, the stud is threaded into the grinding wheel holder.

[0011] Furthermore, the positioning block has a transition slope connecting the low surface and the high surface.

[0012] Furthermore, at least two fixing arms are provided at circumferential intervals on the locking plate.

[0013] Furthermore, a handle is installed on the side of the locking plate.

[0014] Furthermore, the connecting seat and the second end of the grinding wheel shaft are detachably connected through a sleeve engagement.

[0015] In addition, this utility model also provides a vertical gear grinding machine, including the above-mentioned grinding wheel shaft locking structure.

[0016] Compared with the prior art, the above-described technical solutions in this utility model embodiment have at least one of the following beneficial effects: This utility model provides a grinding wheel shaft locking structure and a vertical gear grinding machine. The grinding wheel shaft locking structure includes a connecting seat, a locking plate, a sensor, and a positioning block. The grinding wheel is rotatably mounted on the grinding wheel frame via the grinding wheel shaft. The first end of the grinding wheel shaft is mounted on the grinding wheel frame, and the second end of the grinding wheel shaft is detachably connected to the connecting seat. The connecting seat slides along the axial direction of the grinding wheel shaft onto the grinding wheel frame. The locking plate is rotatably mounted on the connecting seat. By rotating the locking plate on the connecting seat, the connecting seat can be locked onto the grinding wheel frame. The sensor is mounted on the locking plate. The connecting seat is provided with a positioning block opposite to the sensor. The positioning block has a positioning block that extends along the rotation path of the locking plate. When the connecting seat slides close to the grinding wheel on the grinding wheel frame, the sensor aligns with the low surface of the positioning block. When the connecting seat slides close to the grinding wheel and the locking plate rotates into position on the connecting seat, the sensor approaches or contacts the high surface of the positioning block, thereby triggering the sensor's position sensing. Thus, the grinding wheel shaft locking structure provided by this utility model, through its design, sequentially slides the connecting seat on the grinding wheel frame during installation, and then the locking plate rotates, causing the sensor to contact the high surface of the positioning block as the locking plate rotates, thereby triggering the sensor's position sensing. Compared with the prior art, this reduces the number of sensors and lowers the cost of the equipment. Attached Figure Description

[0029] Throughout this specification, reference to "an embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of this application. Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, a particular feature, structure, or characteristic may be combined in any suitable manner.

[0030] Please refer to Figures 1 to 6As shown, the grinding wheel shaft locking structure provided by this utility model will now be described. This grinding wheel shaft locking structure includes a grinding wheel frame 100, a grinding wheel shaft 200, a grinding wheel 300, a connecting seat 1, a locking plate 2, a sensor 3, and a positioning block 4. The grinding wheel 300 is rotatably fitted onto the grinding wheel frame 100 via the grinding wheel shaft 200. The first end of the grinding wheel shaft 200 is mounted on the grinding wheel frame 100, and the second end of the grinding wheel shaft 200 is detachably connected to the connecting seat 1. The connecting seat 1 is slidably fitted onto the grinding wheel frame 100 along the axial direction of the grinding wheel shaft 200. The locking plate 2 is rotatably fitted onto the connecting seat 1. Rotation of the locking plate 2 onto the connecting seat 1 locks the connecting seat 1 onto the grinding wheel frame 100. The sensor 3 is mounted on the locking plate 2. The connecting seat 1 is provided with a positioning block 4 opposite to the sensor 3. The positioning block 4 is provided with... The locking plate 2 has a low surface 41 and a high surface 42 distributed along its rotation path. When the connecting seat 1 slides on the grinding wheel frame 100 and approaches the grinding wheel 300, the sensor 3 aligns with the low surface 41 of the positioning block 4. When the connecting seat 1 slides close to the grinding wheel 300 and the locking plate 2 rotates on the connecting seat 1, the sensor 3 approaches or contacts the high surface 42 of the positioning block 4, thereby triggering the sensor 3 to sense. Thus, the grinding wheel shaft locking structure provided in this embodiment of the present invention is designed so that when the connecting seat 1 is installed, it slides on the grinding wheel frame 100 in sequence, and then the locking plate 2 rotates, so that the sensor 3 approaches or contacts the high surface 42 of the positioning block 4 as the locking plate 2 rotates, thereby triggering the sensor 3 to sense. Compared with the prior art, this reduces the number of sensors and lowers the cost of the equipment.

[0031] like Figure 6 As shown, in some embodiments, a guide rod 5 is provided on the connecting seat 1. The guide rod 5 is inserted into and slidably engaged with the grinding wheel frame 100. When the guide rod 5 on the connecting seat 1 is inserted into the grinding wheel frame 100, the sensor 3 is aligned with the low surface 41 on the positioning block 4.

[0032] like Figure 6 As shown, in some embodiments, the locking plate 2 has a ring-shaped structure.

[0033] like Figure 5 and Figure 6As shown, in some embodiments, a fixing arm 21 is provided on the side of the locking plate 2, and a bayonet 22 is provided on the fixing arm 21. A stud 6 is provided on the grinding wheel frame 100, and a stud end 61 is provided at the end of the stud 6, which protrudes radially around the stud 6. The locking plate 2 rotates, causing the fixing arm 21 to rotate until the bayonet is engaged with the stud 6. At the same time, the stud end 61 is located on the side of the fixing arm 21 away from the grinding wheel shaft 200, so that the contact between the stud 6 and the bayonet 22 can lock the connection. The rotation angle of the fixed plate 2 serves as a limit, and the stud end 61 forms an axial limit on the fixed arm 21 to prevent the connecting seat 1 from sliding and loosening on the grinding wheel frame 100. More precisely, in this embodiment, the stud 6 is threadedly engaged with the grinding wheel frame 100. Thus, by rotating the stud 6 on the grinding wheel frame 100, the stud end 61 can be pressed against the fixed arm 21, so that the frictional resistance generated by the pressing between the stud end 61 and the fixed arm 21 can lock the rotation of the locking plate 2.

[0034] like Figure 4 As shown, in some embodiments, the positioning block 4 has a transition slope between the low surface 41 and the high surface 42 to prevent the sensor 3's contacts from being damaged by impact when moving between the low surface 41 and the high surface 42.

[0035] like Figure 6 As shown, in some embodiments, at least two fixing arms 21 are provided on the locking plate 2 at circumferential intervals to balance the force on the connecting seat 1 and prevent the connecting seat 1 from undergoing torsional deformation relative to the grinding wheel frame 100 when under force.

[0036] like Figure 6 As shown, in some embodiments, a grip 23 is mounted on the side of the locking plate 2.

[0037] In some embodiments, the connecting seat 1 and the second end of the grinding wheel shaft 200 are detachably connected by a sleeve engagement, so that the connecting seat 1 provides stable support for the second end of the grinding wheel shaft 200 when installed in place. It can be understood that the second end of the grinding wheel shaft 200 is inserted into the connecting seat 1, or the connecting seat 1 is inserted into the second end of the grinding wheel shaft 200.

[0038] In some embodiments, sensor 3 is a position sensor, specifically a contact position sensor. It is understood that in other embodiments not shown, sensor 3 is a proximity position sensor.

[0039] This utility model embodiment also provides a vertical gear grinding machine, including the aforementioned grinding wheel shaft locking structure.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
