Description

Technical Field

[0001] The present invention relates to the field of gear processing, and specifically relates to a gear processing technology that improves processing efficiency based on gear grinding technology. Background Art

[0002] Traditional gear grinding processes usually require the workpiece to be adjusted and fixed one by one on the machine tool, and the grinding operation can only be carried out after precise alignment. This processing method not only relies on multiple workpiece clamping, but also requires frequent replacement of workstations or adjustment of processing angles to ensure the processing accuracy of each tooth surface. This process has complicated the operation steps and significantly extended the processing time. Especially for gears with more tooth grooves or complex tooth profiles, the problems of cumbersome processes and low efficiency are more prominent.

[0003] In actual production, the traditional method is often restricted by the following:

[0004] The processing of each tooth surface usually requires repositioning and clamping the workpiece, and the clamping process is time-consuming and laborious, increasing the non-processing time of production.

[0005] Since all tooth surfaces cannot be processed through one clamping, the traditional grinding process often completes them one by one with independent processing paths, making the processing flow not smooth enough.

[0006] Frequent workstation replacement and clamping adjustment not only extend the processing time, but also increase the production cost, making it difficult to meet the requirements of high-efficiency production. Summary of the Invention

[0007] To solve the above problems, the present invention provides a gear processing technology that improves processing efficiency based on gear grinding technology. By driving the gear to be processed to rotate circumferentially through a circumferential rotation method, grinding can be smoothly achieved, greatly improving the gear processing efficiency.

[0008] The present invention is achieved through the following technical solutions: A gear processing technology that improves processing efficiency based on gear grinding technology, including:

[0009] A gear support mechanism, on which the gear to be processed is installed, and the gear support mechanism can adjust the rotational resistance between it and the gear to be processed;

[0010] A driving mechanism, located on one side of the gear mechanism, with a driving disk installed on the driving mechanism. A driving gear grinding mechanism is provided on the outer circumference of the driving disk corresponding to each tooth groove of the gear to be processed, and the pitch between adjacent driving gear grinding mechanisms is the same as the pitch between adjacent two teeth of the gear to be processed;

[0011] The processing technology is as follows:

[0012] Step 1: Mount the gear to be processed on the gear support mechanism;

[0013] Step 2: Adjust the rotational resistance between the gear support mechanism and the gear to be processed according to the grinding accuracy and grinding value required for the gear to be processed;

[0014] Step 3: Turn on the driving mechanism to drive the driving disc and the driving gear grinding mechanism. The driving gear grinding mechanism contacts the grinding surface of the gear to be processed, and uses the circular rotation power to make the driving gear grinding mechanism contact the grinding surface of the gear to be processed;

[0015] Step 4: Use the circular rotation power of the driving disc to drive the gear to be processed to perform circular motion, and by controlling the circular rotation direction of the driving disc, efficient grinding of the gear to be processed is achieved.

[0016] As a preferred technical solution, the driving gear grinding mechanism includes a main body portion. The main body portion has four connecting surfaces, and the included angle between adjacent connecting surfaces is 90 degrees. The main body portion is fixedly connected to the outer circular surface of the driving disc through a connecting column;

[0017] A clamping plate is arranged on each connecting surface, and an elastic grinding sheet is arranged in each clamping plate;

[0018] A grinding included angle A is formed between the elastic grinding sheets on the left and right sides. The grinding sheets respectively contact the grinding surfaces of each tooth to be processed. The grinding positions of the grinding surfaces include an upper grinding contact position and a lower grinding contact position. When the elastic grinding sheets drive the gear to be processed to rotate circularly, the upper grinding contact position and the lower grinding contact position respectively frictionally contact the corresponding elastic grinding sheets. After overcoming the frictional resistance, the gear to be processed rotates circularly.

[0019] As a preferred technical solution, a rotating shaft is arranged between the clamping plate and the main body portion, and a torsion spring is installed on each rotating shaft. Through the rotating shaft, the elastic grinding sheet can fit the upper grinding contact position and the lower grinding contact position.

[0020] As a preferred technical solution, the driving mechanism includes a driving motor. The output end of the driving motor is connected to the driving disc, and the circular reciprocating rotation of the driving disc is controlled by the driving motor.

[0021] As a preferred technical solution, the gear support mechanism includes a support table. A support column is fixedly arranged on the upper end surface of the support table. An elastic expansion member is sleeved outside the support column, and the gear to be processed is sleeved outside the elastic expansion member.

[0022] As a preferred technical solution, the elastic expansion member is made of an elastic rubber material, and has an air storage cavity inside. The elastic expansion member has an air charging / discharging interface, and the air charging / discharging interface is connected to an air pump through a connecting pipe. The friction force between the elastic expansion member and the gear to be processed is increased by inflating the elastic expansion member.

[0023] As a preferred technical solution, the width of the elastic grinding sheet is greater than the widths of the upper grinding contact position and the lower grinding contact position.

[0024] As a preferred technical solution, an elastic grinding sheet capable of being disassembled and assembled is arranged in each clamping plate, and the elastic grinding sheet is locked and fixed to the clamping plate by screws.

[0025] The beneficial effects of the present invention are as follows: By adopting a processing method driven by a gear to rotate, the circumferential motion of the driving disc is used to drive the driving gear grinding mechanism, so that the driving gear grinding mechanism contacts the tooth surface of the gear to be processed and realizes grinding;

[0026] Compared with the traditional method of adjusting and switching the clamping stations one by one, the process of the present invention can be clamped once, and the meshing motion of the driving gear is directly driven by the circumferential rotation, so as to efficiently complete the grinding of each tooth surface;

[0027] Such a design not only greatly reduces the complex clamping adjustment time and the operation of switching stations, but also ensures the smoothness of the processing process and avoids the cumbersome multi-step processes.

[0035] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0036] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example in a series of equivalent or similar features.

[0037] As Figures 1 - 4 As shown, a gear processing technology for improving processing efficiency based on gear grinding technology of the present invention includes a gear support mechanism. The gear 7 to be processed is installed on the gear support mechanism. The gear support mechanism can adjust the rotational resistance between the gear support mechanism and the gear to be processed. The greater the rotational resistance, the more the grinding amount during grinding. Conversely, the smaller the rotational resistance, the smaller the grinding amount during grinding.

[0038] It further includes a driving mechanism located on one side of the gear mechanism. A driving disk 1 is installed on the driving mechanism. A driving gear grinding mechanism 3 is provided on the outer circumference of the driving disk 1 corresponding to each tooth groove 5 of the gear to be processed. The pitch between adjacent driving gear grinding mechanisms 3 is the same as the pitch between adjacent two teeth of the gear to be processed. In this way, when the driving disk 1 rotates circumferentially, each driving gear grinding mechanism 3 can cut into the tooth groove 5 of the gear to be processed and drive the circumferential rotation of the gear to be processed, thereby realizing the switching of each tooth groove 5 of the processed gear.

[0039] The processing technology is as follows:

[0040] Step 1: Support and install the gear 7 to be processed on the gear support mechanism.

[0041] Step 2: Adjust the rotational resistance between the gear support mechanism and the gear to be processed according to the grinding accuracy and grinding value required for the gear to be processed.

[0042] Step 3: Turn on the driving mechanism to drive the driving disk 1 and the driving gear grinding mechanism 3. Through the driving gear grinding mechanism 3 contacting the grinding surface of the gear to be processed, the driving gear grinding mechanism 3 is made to contact the grinding surface of the gear to be processed by using the circumferential driving force.

[0043] Step 4: Use the circumferential rotation power of the driving disk 1 to drive the gear 7 to be processed to perform a circumferential movement, and by controlling the circumferential rotation direction of the driving disk 1, efficient grinding of the gear to be processed is achieved.

[0044] Specifically, as Figure 4 shown, the gear grinding mechanism 3 includes a main body portion 32. The main body portion 32 has four connecting surfaces, and the included angles between adjacent connecting surfaces are all 90 degrees. The main body portion 32 is fixedly connected to the outer circumferential surface of the driving disk 1 through a connecting column 34;

[0045] A clamping plate 31 is arranged on each connecting surface, and an elastic grinding sheet 33 is arranged in each clamping plate 31;

[0046] A grinding included angle A is formed between the elastic grinding sheets 33 on the left and right sides. The grinding sheets are respectively in contact with the grinding surfaces of each tooth to be processed. The grinding positions of the grinding surfaces include an upper grinding contact position 71 and a lower grinding contact position 72. When the elastic grinding sheets 33 drive the gear to be processed to rotate circumferentially, the upper grinding contact position 71 and the lower grinding contact position 72 are respectively in frictional contact with the corresponding elastic grinding sheets 33. After overcoming the frictional resistance, the gear 7 to be processed rotates circumferentially;

[0047] When the driving mechanism drives the driving disk 1 to rotate circumferentially, since the gear 7 to be processed is in a static state, the elastic grinding sheets 33 will rub against the upper grinding contact position 71 and the lower grinding contact position 72 of the gear to be processed. Due to the frictional resistance of the gear to be processed, when encountering a driving force during circumferential movement, at the beginning, it will only cause the elastic grinding sheets 33 to elastically deform. The elastic deformation of the elastic grinding sheets 33 will relatively rub against the upper grinding contact position 71 and the lower grinding contact position 72, thereby achieving the purpose of grinding. After continuing to rotate, the elastic deformation force of the elastic grinding sheets 33 becomes larger and larger. At this time, the frictional resistance of the gear to be processed can be overcome, and the purpose of circumferential rotation is achieved, realizing the switching of the tooth grooves 5 of the gear to be processed. As Figure 4 shown by the arrow, the elastic grinding sheets 33 can be made of elastic metal materials, and a grinding layer can be provided on the surface in contact with the gear. In the present invention, only by rotating circumferentially and realizing the switching of the tooth grooves 5 of the gear to be processed, the grinding work can be completed, greatly improving the processing efficiency.

[0048] Wherein, a rotating shaft 35 is arranged between the clamping plate 31 and the main body portion 32, and a torsion spring is installed on the rotating shaft 35, so that the elastic grinding sheet 33 can be attached to the upper grinding contact position 71 and the lower grinding contact position 72 through the rotating shaft 35.

[0049] The driving mechanism includes a driving motor 2. The output end of the driving motor 2 is connected to the driving disk 1, and the driving disk 1 is controlled by the driving motor 2 to perform a circumferential reciprocating rotation, as Figure 2 shown.

[0050] The gear support mechanism includes a support table 4. A support column 8 is fixedly arranged on the upper end surface of the support table 4. An elastic expansion member 6 is sleeved outside the support column 8. The gear 7 to be processed is sleeved outside the elastic expansion member 6.

[0051] In this embodiment, the elastic expansion member 6 is made of elastic rubber material and has an air storage cavity inside. The elastic expansion member 6 has an air charging and discharging interface 9. The air charging and discharging interface 9 is connected to an air pump through a connecting pipe. By inflating the elastic expansion member 6, the frictional force between the elastic expansion member 6 and the gear to be processed is increased. According to the required grinding value, the inflation amount of the elastic expansion member 6 is set. The larger the inflation amount, the greater the degree of expansion, the greater the frictional resistance with the gear to be processed, and the greater the grinding amount during grinding. Conversely, it is smaller.

[0052] Wherein, the width of the elastic grinding sheet 33 is greater than the widths of the upper grinding contact position 71 and the lower grinding contact position 72. The elastic grinding sheet 33 can be replaced according to the depth of the tooth groove 5, so that the elastic grinding sheet 33 can exactly cover the width of the tooth groove 5 to achieve better grinding.

[0053] In order to realize the regular replacement of the elastic grinding sheet 33, in this embodiment, a detachable elastic grinding sheet 33 is arranged in each clamping plate 31. The elastic grinding sheet 33 is locked and fixed to the clamping plate 31 through screws.

[0054] The beneficial effect of the present invention is that: by adopting the processing method of driving rotation by gears, the circumferential movement of the driving disk 1 drives the driving gear grinding mechanism 3, so that the driving gear grinding mechanism 3 contacts the tooth surface of the gear to be processed and realizes grinding;

[0055] Compared with the traditional method of adjusting and switching the clamping stations one by one, the process of the present invention can be clamped once, and the meshing movement of the gear is directly driven by the circumferential rotation, so as to efficiently complete the grinding of each tooth surface;

[0056] This not only greatly reduces the complex clamping adjustment time and the operation of switching stations, but also ensures the smoothness of the processing process and avoids the cumbersome multi-step processes.

[0057] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that is thought of without creative labor should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
