Description
Technical Field
[0001] This utility model relates to the field of hobbing technology, specifically a clamping hobbing holder that is easy to disassemble and maintain. Background Technology
[0002] A hob is a gear machining tool with teeth arranged in a helical pattern along a cylinder or cone. It is used to machine cylindrical gears, worm gears, and other cylindrical toothed workpieces using the generating method. Depending on the application, hobs are classified into gear hobs, worm gear hobs, non-involute generating hobs, and fixed hobs, etc.
[0003] Based on the above, the applicant believes the following deficiencies exist:
[0004] The existing device cannot achieve initial positioning quickly during installation, requiring additional measuring tools to calibrate the position. This not only increases the difficulty of installation but also easily leads to positioning deviations, affecting the installation accuracy of the subsequent cutter bar. Furthermore, disassembly requires the use of multiple complex tools such as wrenches and screwdrivers, involves numerous disassembly steps, and consumes a significant amount of time to remove bolts, nuts, and other connecting parts, greatly extending the maintenance and replacement cycle of the cutter bar. During maintenance, surrounding components are easily damaged, increasing maintenance costs and reducing the overall operating efficiency of the equipment. Utility Model Content
[0005] The purpose of this invention is to provide a clamping hob holder that is easy to disassemble and maintain, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping hob holder that is easy to disassemble and maintain, comprising a base plate, a main seat fixedly connected to the top left side of the base plate, a clamping fixing mechanism provided on the surfaces of the base plate and the main seat, and an auxiliary sealing mechanism provided on the surface of the base plate;
[0007] The clamping fixing mechanism includes a pressure knife seat, which is disposed on the top of the main seat. Insertion blocks are fixedly connected to the left and right sides of the front and rear ends of the bottom of the pressure knife seat. A retractable insertion block is fixedly connected to the bottom outer end of each insertion block. Insertion interfaces are provided on the left and right sides of the front and rear ends of the top of the main seat. Side connection ports are provided on the left and right sides of the front and back of the main seat. Spring holes are provided on the surface of the main seat. A spring post is fixedly connected inside the spring hole, and a pressure block is fixedly connected to the outer end of the spring post. The pressure knife seat precisely aligns with the insertion interfaces of the main seat through the insertion blocks at its bottom, achieving initial positioning without the need for complex tools. During disassembly, simply press the pressure block on the main seat. The extension and retraction of the spring column within the spring hole releases the limiting position of the retractable insert in the opposite connection port, allowing the pressure seat to be removed directly upwards. This significantly shortens the maintenance and replacement time of the hob. After the insert block is inserted into the connector, the retractable insert is locked inside the side connection port. The spring column pushes the pressure block to press and limit the retractable insert, forming a double fixing structure. This effectively prevents the hob seat from loosening due to vibration during operation, ensuring the running accuracy of the hob. The clamping fixing mechanism enables efficient and convenient disassembly and assembly, reducing maintenance difficulty. The overall fixing is stable and reliable, ensuring stable operation.
[0008] Preferably, the plug block is inserted into the plug interface, and the plug block corresponds one-to-one with the plug interface, and the inner end of the side connection port corresponds to the bottom end of the plug interface.
[0009] Preferably, the retractable insert is disposed inside the side connection port, the pressure block is fixedly connected to the end of the spring column away from the spring hole, and the inner end of the pressure block is disposed inside the side connection port.
[0010] Preferably, the auxiliary sealing mechanism includes insertion holes located at the bottom of the front and rear ends of the right side of the main seat and at the top of the front and rear ends of the right side of the pressure knife seat. A sealing and fixing housing is provided on the right side of the main seat and the pressure knife seat. Insertion posts are fixedly connected to the four corners of the left side of the sealing and fixing housing. A sealing ring is installed inside the sealing and fixing housing. A support base is fixedly connected to the center of the top right side of the base plate. Auxiliary insertion holes are provided at the front and rear ends of the top of the support base. A top limiting seat is provided on the top of the support base. Auxiliary insertion posts are fixedly connected to the front and rear ends of the bottom of the top limiting seat. The sealing and fixing housing is inserted into the insertion holes of the main seat and the pressure knife seat through the insertion posts at the four corners. The internal sealing ring fits tightly against the component connections, effectively preventing dust, debris, and other impurities from entering the main seat and pressure cutter seat. This reduces wear on core components such as the roller cutter rod and extends the overall service life of the equipment. The support seat on the base plate and the top limit seat are connected by auxiliary plug-in columns and auxiliary plug holes, providing stable support for the right side of the pressure cutter seat and the main seat. Together with the sealed and fixed housing, they form a complete lateral fixing structure, further enhancing the overall structural strength of the roller cutter seat and preventing component displacement under stress. The auxiliary sealing mechanism improves the sealing effect, resulting in excellent sealing performance, extending component life, strengthening overall support, and enhancing structural stability.
[0011] Preferably, the plug is inserted into the socket, and the auxiliary plug is inserted into the auxiliary socket.
[0012] Preferably, auxiliary mounting seats are fixedly connected to both the left and right sides of the front and back of the base plate, and a hobbing rod is provided at the inner end of the main seat and the pressure seat.
[0013] Compared with the prior art, this utility model provides a clamping hob holder that is easy to disassemble and maintain, and has the following beneficial effects:
[0014] 1. This easy-to-disassemble and maintain clamping hob holder features a clamping fixing mechanism. The clamping holder precisely aligns with the main seat's insertion interface via a bottom plug, allowing for initial positioning without complex tools. During disassembly, simply press the pressure block on the main seat; the spring column's expansion and contraction within the spring hole releases the limiting position of the retractable plug in the opposite connection port, allowing direct upward removal of the clamping holder. This significantly reduces the time required for hob maintenance and replacement. After the plug is inserted into the insertion interface, the retractable plug engages inside the side connection port, and the spring column pushes the pressure block to clamp and limit the retractable plug, forming a double-fixing structure. This effectively prevents the hob holder from loosening due to vibration during operation, ensuring the hob's running accuracy. The clamping fixing mechanism enables efficient and convenient disassembly and assembly, reducing maintenance difficulty. The overall fixation is stable and reliable, ensuring stable operation.
[0015] 2. This easy-to-disassemble and maintain clamping cutter holder is equipped with an auxiliary sealing mechanism. The sealing and fixing housing is inserted into the insertion holes of the main seat and the pressure cutter seat through the four corner plugs. The sealing ring installed inside can tightly fit the connection of the components, effectively preventing dust, debris and other impurities from entering the interior of the main seat and the pressure cutter seat, reducing the wear of core components such as the cutter rod, and extending the overall service life of the equipment. The support seat on the base plate and the top limit seat are connected by auxiliary plugs and auxiliary insertion holes, which not only provides stable support for the right side of the pressure cutter seat and the main seat, but also forms a complete lateral fixing structure together with the sealing and fixing housing, further improving the overall structural strength of the cutter holder, preventing the components from shifting under force, improving the sealing effect through the setting of the auxiliary sealing mechanism, providing excellent sealing performance, extending the service life of components, strengthening the overall support, and improving structural stability.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0024] This utility model provides the following technical solution:
[0025] Example 1
[0026] Please see Figure 1-4 A clamping hob holder that is easy to disassemble and maintain includes a base plate 1, a main seat 3 fixedly connected to the top left side of the base plate 1, a clamping fixing mechanism 4 provided on the surface of the base plate 1 and the main seat 3, and an auxiliary sealing mechanism 5 provided on the surface of the base plate 1.
[0027] The clamping fixing mechanism 4 includes a pressure knife seat 41, which is located on the top of the main seat 3. Insertion blocks 42 are fixedly connected to the left and right sides of the front and rear ends of the bottom of the pressure knife seat 41. A retractable insertion block 43 is fixedly connected to the bottom of the outer end of the insertion block 42. Insertion interfaces 44 are opened on the left and right sides of the front and rear ends of the top of the main seat 3. Side connection ports 45 are opened on the left and right sides of the front and back of the main seat 3. Spring holes 46 are opened on the surface of the main seat 3. Spring pillars 47 are fixedly connected inside the spring holes 46. Pressure blocks 48 are fixedly connected to the outer ends of the spring pillars 47. The pressure knife seat 41 is precisely inserted into the insertion interfaces 44 of the main seat 3 through the insertion blocks 42 at the bottom, and the initial positioning can be completed without complicated tools. During disassembly, simply press the pressure block 48 on the main seat 3. Through the telescopic deformation of the spring column 47 in the spring hole 46, the limit of the telescopic insert 43 in the opposite connection port 45 can be released, and the pressure knife seat 41 can be directly taken out upwards. This greatly shortens the maintenance and replacement time of the hob rod 6. After the insert block 42 is inserted into the insert interface 44, the telescopic insert 43 is inserted into the side connection port 45. With the help of the spring column 47, the pressure block 48 is pushed to press and limit the telescopic insert 43, forming a double fixing structure. This can effectively prevent the hob seat from loosening due to vibration during operation, ensuring the running accuracy of the hob rod 6. The clamping fixing mechanism 4 enables efficient and convenient disassembly and assembly, reduces maintenance difficulty, and ensures stable operation.
[0028] The plug block 42 is inserted into the plug interface 44. The plug block 42 and the plug interface 44 correspond one-to-one. The inner end of the side connection port 45 corresponds to the bottom end of the plug interface 44.
[0029] The retractable insert 43 is located inside the side connection port 45, and the pressure block 48 is fixedly connected to the end of the spring post 47 away from the spring hole 46. The inner end of the pressure block 48 is located inside the side connection port 45.
[0030] Example 2
[0031] Please see Figure 1-4Furthermore, based on Embodiment 1, the auxiliary sealing mechanism 5 includes insertion holes 51. Insertion holes 51 are located at the bottom of the front and rear ends of the right side of the main seat 3 and at the top of the front and rear ends of the right side of the pressure knife seat 41. A sealing and fixing housing 52 is provided on the right side of the main seat 3 and the pressure knife seat 41. Insertion posts 53 are fixedly connected to the four corners of the left side of the sealing and fixing housing 52. A sealing ring 54 is installed inside the sealing and fixing housing 52. A support seat 55 is fixedly connected to the center of the top right side of the base plate 1. Auxiliary insertion holes 56 are provided at the front and rear ends of the top of the support seat 55. A top limiting seat 57 is provided on the top of the support seat 55. Auxiliary insertion posts 58 are fixedly connected to the front and rear ends of the bottom of the top limiting seat 57. The sealing and fixing housing 52 is inserted into the main seat 3 and the pressure knife seat through the insertion posts 53 at the four corners. The sealing ring 54 installed inside the insertion hole 51 of the base 41 can fit tightly against the component connection, effectively preventing dust, debris and other impurities from entering the interior of the main base 3 and the pressure knife base 41, reducing the wear of core components such as the roller rod 6, and extending the overall service life of the equipment. The support base 55 on the base plate 1 and the top limit base 57 are connected by the auxiliary insertion post 58 and the auxiliary insertion hole 56, which not only provides stable support for the right side of the pressure knife base 41 and the main base 3, but also forms a complete lateral fixing structure together with the sealing and fixing housing 52, further improving the overall structural strength of the roller base, preventing the components from shifting under force, and improving the sealing effect through the setting of the auxiliary sealing mechanism 5, with excellent sealing performance, extending the service life of the components, strengthening the overall support, and improving the structural stability.
[0032] The plug-in post 53 is inserted into the socket 51, and the auxiliary plug-in post 58 is inserted into the auxiliary socket 56;
[0033] Auxiliary mounting bases 2 are fixedly connected to the left and right sides of the front and back of the base plate 1, and a hobbing rod 6 is provided inside the main base 3 and the pressure knife base 41.
[0034] In actual operation, when this device is used, the hobbing rod 6 is placed inside the main seat 3 and then fixed by the clamping fixing mechanism 4. The pressure seat 41 is precisely inserted into the insertion interface 44 of the main seat 3 through the bottom insertion block 42, and the initial positioning can be completed without complicated tools. During disassembly, simply press the pressure block 48 on the main seat 3. Through the telescopic deformation of the spring column 47 in the spring hole 46, the limit of the telescopic insert 43 in the opposite connection port 45 can be released, and the pressure knife seat 41 can be directly taken out upwards. This greatly shortens the maintenance and replacement time of the hob rod 6. After the insert block 42 is inserted into the insert interface 44, the telescopic insert 43 is inserted into the side connection port 45. With the help of the spring column 47, the pressure block 48 is pushed to press and limit the telescopic insert 43, forming a double fixing structure. This can effectively prevent the hob seat from loosening due to vibration during operation, ensuring the running accuracy of the hob rod 6. The clamping fixing mechanism 4 enables efficient and convenient disassembly and assembly, reduces maintenance difficulty, and ensures stable operation.
[0035] Next, the sealing and fixing housing 52 is inserted into the insertion holes 51 of the main seat 3 and the pressure cutter seat 41 through the four corner plug-in posts 53. The sealing ring 54 installed inside can tightly fit the connection of the components, effectively preventing dust, debris and other impurities from entering the interior of the main seat 3 and the pressure cutter seat 41, reducing the wear of core components such as the hob rod 6, and extending the overall service life of the equipment. The support seat 55 on the base plate 1 and the top limit seat 57 are connected by auxiliary plug-in posts 58 and auxiliary insertion holes 56, which not only provides stable support for the right side of the pressure cutter seat 41 and the main seat 3, but also together with the sealing and fixing housing 52 form a complete lateral fixing structure, further improving the overall structural strength of the hob rod seat and preventing the components from shifting under force. The setting of the auxiliary sealing mechanism 5 improves the sealing effect, has excellent sealing performance, extends the service life of the components, strengthens the overall support, and improves the structural stability. Finally, the base plate 1 is installed on the machine tool through the auxiliary mounting seat 2 for use. During maintenance, the hob rod 6 and the hob on the surface can be maintained and replaced without disassembling the base plate 1.
