Description

Technical Field

[0001] The invention relates to the field of gear processing technology, and specifically to a gear end face grinding device. Background Technology

[0002] Gears are transmission mechanical devices. A gear is a mechanical element with teeth on its rim that can continuously mesh to transmit motion and power. After processing, gears need to be ground and polished to reduce the friction coefficient of the gear surface, thereby reducing the noise generated when the gear is running.

[0003] Although gear surface treatment devices meet users' needs to a certain extent, they still have certain shortcomings in actual use. The specific problems are as follows: existing gears require multiple grinding and polishing processes, including tooth grinding and end face grinding. It is not convenient to grind the end face simultaneously during tooth grinding. Furthermore, the top and bottom of the gear are prone to burrs during tooth grinding, which cause burrs from tooth grinding to enter the gear end face and burrs from end face grinding to enter the tooth area. This results in the need for cleaning again after the entire gear is ground, thus affecting the grinding efficiency. Summary of the Invention

[0004] The technical problem to be solved by the invention is to provide a gear end face grinding device that can transport gears and simultaneously grind the gear teeth and end faces during the transport process, thereby solving the problems mentioned in the background art.

[0005] The invention is achieved through the following technical solution: a gear end face grinding device, including an upper grinding plate, a lower grinding plate, and a gear. The upper and lower grinding plates are arranged parallel to each other, one above the other. A fixing frame connecting the two is installed on one side of the upper and lower grinding plates. A strip-shaped opening is provided laterally in the middle of the lower grinding plate. The gear is placed on the upper surface of the lower grinding plate. A drive mechanism is provided at the lower end of the lower grinding plate to drive the gear to move laterally along the upper and lower grinding plates. A vertical plate is provided on the side of the upper and lower grinding plates away from the fixing frame. Multiple grinding strips are installed on one side of the vertical plate. The grinding strips are meshed with the gear and are linked with the drive mechanism to drive the gear to rotate and grind.

[0006] As a preferred technical solution, the drive mechanism includes an electric slide, a column, a positioning rod, and a push rod. The electric slide is located inside the side plate and is parallel to the lower grinding plate. The column is mounted on the moving platform of the electric slide and is positioned opposite to the slot. The push rod is located at the upper end of the column, and the upper end of the push rod passes through the slot and is inserted into the center hole of the gear. A positioning groove is provided on the bottom surface of the push rod. The lower end of the positioning rod is mounted on the top surface of the column, and the upper end is inserted into the positioning groove and is equipped with a first compression spring. The other end of the first compression spring is mounted on the inner wall of the positioning groove.

[0007] As a preferred technical solution, the drive mechanism also includes a guide rod. The inner side of the vertical plate is provided with a serpentine guide groove. One end of the guide rod is installed on the moving platform of the electric slide table and is located on the side of the moving platform. The other end of the guide rod is inserted into the guide groove.

[0008] As a preferred technical solution, the lower end of the drive mechanism is provided with a base plate, and multiple support frames are installed between the base plate and the fixed frame. A fixed seat is formed by protrusion on the top surface of the base plate. The fixed seat is installed on the bottom surface of the drive mechanism. Multiple positioning holes are provided on the bottom surface of the vertical plate. Positioning pins are provided in each positioning hole. The lower ends of the positioning pins are all installed on the top surface of the base plate. A second compression spring is installed on one end of the positioning pin inside the positioning hole. The other end of the second compression spring is installed on the inner wall surface of the positioning hole.

[0009] As a preferred technical solution, the lower grinding plate is longer than the upper grinding plate. The extra end of the lower grinding plate is the tooth-grooving area for inserting the gear, and the extra end of the lower grinding plate is the tooth-removing area for taking out the gear. The distance between the upper and lower grinding plates is matched with the thickness of the gear.

[0010] As a preferred technical solution, the length of the fixing frame matches the length of the lower grinding plate, and the side of the gear away from the vertical plate contacts the inner side of the fixing frame.

[0011] As a preferred technical solution, the opposing surfaces of the upper and lower grinding plates are grinding end faces, which are in contact with the top and bottom surfaces of the gear.

[0012] As a preferred technical solution, both the positioning groove and the positioning rod have rectangular cross-sections.

[0013] As a preferred technical solution, the end of the guide rod away from the electric slide table forms a hemispherical guide section, which contacts the inner wall of the guide groove, and the cross-section of the guide rod is circular.

[0014] As a preferred technical solution, the outer wall surface of the polishing strip is provided with polishing texture.

[0015] The beneficial effects of the invention are: 1. The gear can be placed directly on the toothed area of ​​the lower grinding plate, and the gear can be pushed forward along the lower and upper grinding plates by the push rod that pops up from the bottom. During the movement, the gear can rotate by the obstruction of the grinding strip, so that it can rotate and grind, thereby increasing the quality of grinding.

[0016] 2. During the movement of the push rod, the guide rod is driven synchronously. The guide rod can move along the guide groove. During the movement, it can continuously push the vertical plate upward or downward. The movement of the vertical plate drives the grinding strip, so that the grinding strip can have an up-and-down moving effect, which can simultaneously grind the teeth and grooves on the gear, increasing the comprehensiveness of the grinding.

[0017] 3. The above combination enables this device to grind the end face, teeth and grooves of the gear during the conveying process, thus increasing the grinding efficiency. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention.

[0026] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0027] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a gear end face grinding device of the invention includes an upper grinding plate 1, a lower grinding plate 2, and a gear 6. The upper grinding plate 1 and the lower grinding plate 2 are arranged parallel to each other, one above the other. A fixing frame 3 is installed on one side of the upper grinding plate 1 and the lower grinding plate 2 to connect the two. A strip-shaped opening 11 is provided in the middle of the lower grinding plate 2. The gear 6 is placed on the upper surface of the lower grinding plate 2. A drive mechanism is provided at the lower end of the lower grinding plate 2 to drive the gear 6 to move laterally along the upper grinding plate 1 and the lower grinding plate 2. A vertical plate 4 is provided on the side of the upper grinding plate 1 and the lower grinding plate 2 away from the fixing frame 3. Multiple grinding strips 5 are installed on one side of the vertical plate 4. The grinding strips 5 are meshed with the gear 6 and are linked with the drive mechanism to drive the gear 6 to rotate and grind.

[0029] In this embodiment, the driving mechanism includes an electric slide table 9, a column 8, a positioning rod 16, and a push rod 7. The electric slide table 9 is located on the inner side of the side plate and is parallel to the lower grinding plate 2. The column 8 is installed on the moving platform of the electric slide table 9 and is positioned opposite to the slot 11. The push rod 7 is located at the upper end of the column 8. The upper end of the push rod 7 passes through the slot 11 and is inserted into the center hole of the gear 6. A positioning groove is provided on the bottom surface of the push rod 7. The lower end of the positioning rod 16 is installed on the top surface of the column 8, and the upper end is inserted into the positioning groove and is equipped with a first compression spring. The other end of the first compression spring is installed on the inner wall surface of the positioning groove.

[0030] In this design, the push rod can move downward along the positioning rod. After the push rod is pressed down, it can move out of the center hole in the gear. At this time, the gear can move laterally along the lower grinding plate and can be directly pushed onto other conveying mechanisms without lifting the gear, eliminating the force required for lifting and reducing workload.

[0031] In this embodiment, the driving mechanism also includes a guide rod 14. The inner side of the vertical plate 4 is provided with a serpentine guide groove 13. One end of the guide rod 14 is installed on the moving platform of the electric slide table 9 and is located on the side of the moving platform. The other end of the guide rod 14 is inserted into the guide groove 13.

[0032] In this embodiment, the lower end of the drive mechanism is provided with a base plate 10, and multiple support frames 12 are installed between the base plate 10 and the fixed frame 3. A fixed seat 17 is formed by protrusion on the top surface of the base plate 10. The fixed seat 17 is installed on the bottom surface of the drive mechanism. Multiple positioning holes are provided on the bottom surface of the vertical plate 4. Positioning pins 15 are provided in each positioning hole. The lower ends of the positioning pins 15 are all installed on the top surface of the base plate 10. A second compression spring is installed on one end of the positioning pin 15 inside the positioning hole. The other end of the second compression spring is installed on the inner wall surface of the positioning hole.

[0033] The base plate has fixing holes at all four corners, through which bolts can be passed to fix the base plate to the ground.

[0034] The vertical plate can be positioned on the base plate through the positioning holes and positioning pins, so that the vertical plate can only move back and forth vertically along the positioning pins, and the compression spring can exert an upward pushing force on the vertical plate after it moves downward.

[0035] In this embodiment, the length of the lower grinding plate 2 is greater than that of the upper grinding plate 1. The extra end of the lower grinding plate 2 is the tooth-swinging area for inserting the gear 6, and the extra end of the lower grinding plate 2 is the tooth-removing area for taking out the gear 6. The distance between the upper grinding plate 1 and the lower grinding plate 2 matches the thickness of the gear 6.

[0036] In this embodiment, the length of the fixing frame 3 matches the length of the lower grinding plate 2, and the side of the gear 6 away from the vertical plate 4 contacts the inner side of the fixing frame 3. The fixing frame can limit one side of the gear, so that the gear can only mesh with the grinding strip. The meshing grinding strip can drive the gear to rotate.

[0037] In this embodiment, the opposing surfaces of the upper grinding plate 1 and the lower grinding plate 2 are grinding end faces. The grinding end faces are in contact with the top and bottom surfaces of the gear 6, so that the gear can be directly ground after it enters between the upper grinding plate and the lower grinding plate.

[0038] In this embodiment, both the positioning groove and the positioning rod 16 have rectangular cross-sections, which allows the push rod to move up and down along the positioning rod, avoiding twisting. Furthermore, the push rod has a cylindrical structure, which reduces friction with the gear center hole and allows for better gear pushing, enabling the gear to move and rotate simultaneously.

[0039] In this embodiment, the end of the guide rod 14 away from the electric slide table 9 forms a hemispherical guide section. The guide section contacts the inner wall of the guide groove 13, and the cross-section of the guide rod 14 is circular, making the outer ring and end face of the guide rod relatively smooth, reducing friction with the guide groove, and better pushing the vertical plate upward, so that the vertical plate moves quickly up and down along the positioning rod.

[0040] To ensure the polishing effect, in this embodiment, the outer wall surface of the polishing strip 5 is provided with polishing patterns, and the cross-section of the polishing strip can match the cross-section of the tooth groove, so that the polishing strip can fully contact the tooth groove and increase the comprehensiveness of polishing.

[0041] In use, the gear can be directly fitted onto the push rod, and the bottom end face of the gear can contact the grinding end face of the lower grinding plate. After the electric slide is started, the moving platform on the electric slide can move backward. The movement of the moving platform drives the guide rod, column, positioning rod and push rod. The movement of the push rod can push the gear, so that the gear is conveyed backward along the upper and lower grinding plates. During the conveying process, the top and bottom end faces of the gear can rub against the grinding end faces of the upper and lower grinding plates, thereby polishing them. Since one end of the gear is meshed with the grinding strip, the gear can rotate during the pushing process, so that the gear can convey and polish at the same time, thereby increasing the quality and efficiency of polishing.

[0042] When the mobile platform moves synchronously with the guide rod, the guide rod can move along the guide groove and squeeze the vertical plate, causing the vertical plate to move back and forth up and down along the positioning column. The movement of the vertical plate synchronously drives the grinding strip, which can grind the tooth grooves and teeth of the gear through the up and down movement of the grinding strip. This process can be completed during the movement of the gear, so that the gear has been completely ground after it moves out from between the lower grinding plate and the upper grinding plate, allowing the grinding operation to be carried out during the conveying process.

[0043] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of the invention. Therefore, the scope of protection of the invention should be determined by the scope defined in the claims.
