Description

Technical Field

[0001] The utility model relates to a fixture, in particular to a motor-driven grinding needle fixture for a grinding machine. Background Art

[0002] A grinding machine for needles is a special machine tool dedicated to precision grinding of specific parts of slender rod-shaped metal objects (collectively referred to as "needles").

[0003] At present, the corresponding fixture of the grinding machine for needles has a relatively single function and is difficult to achieve multi-angle grinding of needles. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a motor-driven grinding needle fixture.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: It includes a rotating mechanism, a main frame, a translation motor, a translation seat, a clamping cylinder and a clamping plate. The rotating mechanism drives the main frame to rotate. The translation motor is arranged on the main frame and drives the translation seat to move horizontally. The clamping cylinder is arranged on the translation seat and drives the clamping plate to move longitudinally. The clamping plate has an extension extending to the other side of the main frame relative to the translation seat. The extension has a clamping state that fits against the main frame and fixes the needle.

[0006] By adopting the above technical solutions, when in use, the rotating mechanism drives the overall rotation of the main frame to drive the needle to adjust the circumferential angle; the clamping cylinder drives the longitudinal movement of the extension of the clamping plate to make the extension fit against the main frame to form a clamping force and fix the needle body. The translation motor pushes the translation seat to move horizontally to realize the horizontal feeding of the needle and at the same time play a role in grinding the needle. After adjusting the angle, an additional grinding disc grinds the needle, breaking through the single-degree-of-freedom limitation of the traditional fixture, and realizing the precise adjustment of the spatial pose of the needle body through the coordinated control of three axes, solving the core defect of "difficult to grind at multiple angles" in the background art and providing a basis for complex curved surface grinding.

[0007] The utility model is further arranged as follows: The rotating mechanism includes a rotating motor, a left fixing seat, a right fixing seat and a rotating shaft. The rotating shaft is arranged between the left fixing seat and the right fixing seat and the rotating shaft is horizontally arranged. The rotating motor drives the rotating shaft to rotate, and the main frame is fixedly arranged on the rotating shaft.

[0008] By adopting the above technical solutions, the rotating motor drives the main frame to rotate through the rotating shaft. The left fixing seat and the right fixing seat provide double-end support for the rotating shaft to ensure the rotation stability of the main frame, eliminate the eccentric load vibration caused by a single-sided cantilever, and improve the rotation accuracy; the horizontal layout of the rotating shaft directly transmits the torque to the main frame, reduces the transmission chain error, and ensures the angle consistency of the needle body during high-speed grinding.

[0009] The present utility model is further configured as follows: the clamping plate further has a driving part and a connecting part. The driving part is linked with the clamping cylinder and is parallel to the extending part. The connecting part is located between the driving part and the extending part and is arranged longitudinally. The main frame is provided with a longitudinal track for the longitudinal sliding of the connecting part.

[0010] By adopting the above technical solution, the clamping cylinder pushes the driving part, and drives the extending part to move through the longitudinally connected connecting part; the connecting part slides along the longitudinal track of the main frame to restrict the movement track of the clamping plate.

[0011] The present utility model is further configured as follows: a matching part opposite to the needle is provided on the main frame, a clamping section for clamping with the matching part is provided on the extending part, and a fixing groove opposite to the clamping section is further provided on the extending part.

[0012] By adopting the above technical solution, the needle body is placed between the matching part of the main frame and the clamping section of the extending part; when clamping, the clamping section presses towards the matching part, and the fixing groove restricts the needle body from the bottom.

[0013] The present utility model is further configured as follows: the main frame includes a U-shaped frame, a track box and a main board. The U-shaped frame is hung on a rotating shaft, the track box is arranged inside the opening of the U-shaped frame, the longitudinal track is arranged on the track box, and the matching part is located on the main board.

[0014] By adopting the above technical solution, the U-shaped frame is suspended on the rotating shaft to realize the support of the main body; the longitudinal track is arranged inside the track box to guide the clamping plate; the main board integrates the matching part to directly support the needle body.

[0015] The present utility model is further configured as follows: an arc-shaped concave surface is provided on the other side of the extending part relative to the main frame.

[0016] By adopting the above technical solution, the arc-shaped concave surface is provided to provide enough space for the grinding disc to grind the needle. Description of the Drawings

[0023] As Figures 1-3 shown, the present utility model discloses a motor-driven needle grinding fixture, which includes a rotating mechanism 1, a main frame 2, a translating motor 3, a translating seat 4, a clamping cylinder 5 and a clamping plate 6. The rotating mechanism 1 drives the main frame 2 to rotate. The translating motor 3 is arranged on the main frame 2 and drives the translating seat 4 to move horizontally. The clamping cylinder 5 is arranged on the translating seat 4 and drives the clamping plate 6 to move longitudinally. The clamping plate 6 has an extension part 61 extending to the other side of the main frame 2 relative to the translating seat 4. The extension part 61 has a clamping state of being attached to the main frame 2 and fixing the needle. When in use, the rotating mechanism 1 drives the whole main frame 2 to rotate, driving the needle to adjust the circumferential angle; the clamping cylinder 5 drives the extension part 61 of the clamping plate 6 to move longitudinally, so that the extension part 61 is attached to the main frame 2 to form a clamping force to fix the needle body. The translating motor 3 pushes the translating seat 4 to move horizontally, realizing the horizontal feeding of the needle and at the same time playing a role in grinding the needle. After adjusting the angle, an additional grinding disc grinds the needle, breaking through the single-degree-of-freedom limitation of the traditional fixture, and realizing the precise adjustment of the spatial pose of the needle body through the coordinated control of three axes, solving the core defect of "difficult to grind at multiple angles" in the background technology and providing a basis for complex curved surface grinding.

[0024] The rotating mechanism 1 includes a rotating motor 11, a left fixed seat 12, a right fixed seat 13 and a rotating shaft 14. The rotating shaft 14 is arranged between the left fixed seat 12 and the right fixed seat 13 and is horizontally disposed. The rotating motor 11 drives the rotation of the rotating shaft 14. The main frame 2 is fixedly arranged on the rotating shaft 14. The rotating motor 11 drives the main frame 2 to rotate through the rotating shaft 14. The left fixed seat 12 and the right fixed seat 13 provide double-end support for the rotating shaft 14 to ensure the rotational stability of the main frame 2, eliminate the eccentric load vibration caused by a single-sided cantilever, and improve the rotation accuracy. The horizontal layout of the rotating shaft 14 directly transmits the torque to the main frame 2, reduces the error of the transmission chain, and ensures the angular consistency of the needle body during high-speed grinding.

[0025] The clamping plate 6 also has a driving portion 62 and a connecting portion 63. The driving portion 62 is linked with the clamping cylinder 5 and the driving portion 62 is parallel to the extending portion 61. The connecting portion 63 is located between the driving portion 62 and the extending portion 61 and the connecting portion 63 is longitudinally arranged. The main frame 2 is provided with a longitudinal track 21 for the longitudinal sliding of the connecting portion 63. The clamping cylinder 5 pushes the driving portion 62, and drives the extending portion 61 to move through the longitudinally connected connecting portion 63. The connecting portion 63 slides along the longitudinal track 21 of the main frame 2 to restrict the movement track of the clamping plate 6.

[0026] A mating portion 22 opposite to the needle is provided on the main frame 2. A clamping section 64 for clamping with the mating portion 22 is provided on the extending portion 61. A fixing groove 65 opposite to the clamping section 64 is also provided on the extending portion 61. The needle body is placed between the mating portion 22 of the main frame 2 and the clamping section 64 of the extending portion 61. When clamping, the clamping section 64 presses against the mating portion 22, and the fixing groove 65 restricts the needle body from the bottom.

[0027] The main frame 2 includes a U-shaped frame 23, a track box 24 and a main board 25. The U-shaped frame 23 is hung on the rotating shaft 14. The track box 24 is arranged inside the opening of the U-shaped frame 23. The longitudinal track 21 is arranged on the track box 24. The mating portion 22 is located on the main board 25. The U-shaped frame 23 is suspended on the rotating shaft 14 to achieve the main body support. The longitudinal track 21 is built in the track box 24 to guide the clamping plate 6. The main board 25 integrates the mating portion 22 to directly support the needle body.

[0028] An arc-shaped concave surface 66 is provided on the other side of the extending portion 61 relative to the main frame 2. The arc-shaped concave surface 66 is provided to provide enough space for the grinding disc to grind the needle.

[0029] During the working process, the needle body is placed between the mating part 22 of the main frame 2 and the extension part 61 of the clamping plate 6. The clamping cylinder 5 is started to push the driving part 62, and the extension part 61 is driven to move longitudinally through the rigid guidance of the longitudinal track 21, so that the clamping section 64 and the mating part 22 form the main clamping surface. At the same time, the fixing groove 65 restricts the needle body from the bottom to complete the stable clamping of the needle. The rotating motor 11 drives the overall rotation of the U-shaped frame 23 through the rotating shaft 14 to drive the needle body to adjust the circumferential angle. At the same time, the translation motor 3 drives the translation seat 4 to move horizontally to realize the radial feeding of the needle body. After the multi-angle pose adjustment of the needle body is completed, the grinding wheel performs multi-directional precision grinding on the needle body.
