Description

Technical field:

[0001] The utility model relates to a polishing device for producing a shot head. Background technology:

[0002] The shot head is a metal mold used for casting automobile, electronic and mechanical parts, which has the characteristics of high temperature, high pressure and high speed. After long-term use, the surface of the shot head is prone to wear, corrosion and scratches. Grinding and polishing can remove the wear layer and oxide layer on the surface, restore the finish and flatness of the shot head, extend its service life, and reduce the frequency of replacement and maintenance.

[0003] Chinese patent publication number CN215470402U discloses an automatic polishing device for drill production, including a fixed plate, a rotating clamping device is fixedly installed on the top of the fixed plate, a first connecting plate located on the left side of the rotating clamping device is fixedly installed on the top of the fixed plate, a waist-shaped hole is opened inside the first connecting plate, a sliding plate is slidably connected to the inner side of the waist-shaped hole, a limiting plate is fixedly installed on the left side of the sliding plate, a locking pin in contact with the first connecting plate is threadedly connected to the left side of the limiting plate, an electric push rod is fixedly installed on the right side of the sliding plate, a second connecting plate is fixedly installed on the right side of the electric push rod, a polishing frame is rotatably connected to the bottom of the second connecting plate, and a third connecting plate is fixedly installed on the right side of the second connecting plate. The automatic polishing device for drill production has the advantage of being able to conveniently polish drills of various sizes.

[0004] However, the above patent is not applicable to the polishing of the injection head, which may easily cause one end of the injection head to be clamped and unable to be polished. After replacement after polishing, the polished end will be re-clamped and the polished end will be worn, thereby destroying the polishing effect. Therefore, improvement is needed. Utility model content:

[0005] The utility model aims to improve the problems existing in the prior art, that is, the technical problem to be solved by the utility model is to provide a polishing device for producing injection heads.

[0007] Furthermore, the moving assembly includes a supporting seat plate arranged in parallel and just above the lifting seat plate, the bottom surface of the supporting seat plate is coaxially provided with an annular track, a rotating motor is vertically provided at the center of the annular track, the output shaft of the rotating motor extends downward and is fixed with a horizontal connecting rod, a moving seat is fixed at one end of the horizontal connecting rod away from the rotating motor, and the moving seat is slidably matched with the annular track; the polishing motor is fixedly connected to the moving seat.

[0008] Furthermore, a vertically arranged support frame is fixed to the bottom of the movable seat, and a movable cylinder arranged radially along the circular track is installed on the support frame. The cylinder rod of the movable cylinder extends toward the side where the air expansion shaft is located and the end is connected to the motor frame of the polishing motor to drive the polishing motor to move radially along the circular track.

[0009] Furthermore, the annular track is coaxially distributed with the inflation axis.

[0010] Furthermore, the cross section of the annular track is T-shaped, and the upper end of the movable seat is T-shaped and extends into the annular track.

[0011] Furthermore, the lifting seat plate is driven to lift vertically by a lifting cylinder vertically arranged below the lifting seat plate.

[0012] Furthermore, a vertically arranged cylindrical protective cover is fixed on the outer peripheral side of the support seat plate, the bottom of the protective cover is open and is used to cover the outer side of the lifting seat plate, and the side wall of the protective cover is connected to a dust suction pipe, which is connected to a vacuum cleaner.

[0013] Compared with the prior art, the utility model has the following effects: the utility model has a reasonable structural design, and uses an air expansion shaft to fix the injection head. This fixing method does not contact the outer peripheral side of the injection head. The polishing of the peripheral side of the injection head can be completed by one clamping, and no secondary clamping is required, which effectively avoids the current problem of secondary clamping destroying the polishing effect.

[0018] like Figures 1-2 As shown, the utility model is a polishing device for producing shot heads, comprising a lifting seat plate 1 horizontally arranged directly below the polishing assembly, and a gas expansion shaft 2 for extending into the inner hole of the shot head 3 is vertically arranged in the middle of the top surface of the lifting seat plate 1; the polishing assembly comprises a polishing head 4 vertically arranged on the outer peripheral side of the gas expansion shaft 2, and the polishing head is cylindrical, and the polishing head 4 is driven to rotate by a polishing motor 5 arranged above it, and the polishing motor 5 is driven by a moving assembly to move around the outer peripheral side of the gas expansion shaft. When working, the shot head is vertically sleeved on the outer side of the gas expansion shaft, and the gas expansion shaft is inflated to fix the shot head, and then the lifting seat plate drives the shot head to move upward, so that the positions of the shot head and the polishing head correspond, and finally the moving assembly drives the polishing motor and the polishing head to move around the outer peripheral side of the gas expansion shaft, and the polishing motor drives the polishing head to rotate, and the outer circumferential surface of the polishing head contacts the outer circumferential surface of the shot head, so as to realize the polishing treatment of the outer circumferential surface of the shot head.

[0019] In this embodiment, the moving assembly includes a support seat plate 6 arranged parallel to and just above the lifting seat plate 1, a circular track 7 is coaxially arranged on the bottom surface of the support seat plate 6, a rotating motor 8 is vertically arranged at the center of the circular track 7, the output shaft of the rotating motor 8 extends downward and is fixed with a horizontal connecting rod 9, a moving seat 10 is fixed at one end of the horizontal connecting rod 9 away from the rotating motor 8, and the moving seat 10 is slidably matched with the circular track 7; the polishing motor 5 is fixedly connected with the moving seat 10. When working, the rotating motor drives the horizontal connecting rod to rotate in the horizontal plane, the horizontal connecting rod drives the moving seat to move along the circular track, and the moving seat drives the polishing motor and the polishing head to move synchronously.

[0020] In this embodiment, a vertically arranged support frame 11 is fixed to the bottom of the movable seat 10, and a movable cylinder 12 arranged radially along the circular track 7 is installed on the support frame 11. The cylinder rod of the movable cylinder 12 extends toward the side where the air shaft 2 is located and the end is connected to the motor frame of the polishing motor 5 to drive the polishing motor to move radially along the circular track.

[0021] In this embodiment, the annular track 7 is coaxially distributed with the air expansion shaft 2 .

[0022] In this embodiment, the cross section of the annular track 7 is T-shaped, and the upper end of the movable seat 10 is T-shaped and extends into the annular track, so that the movable seat and the annular track can slide together without falling downward.

[0023] In this embodiment, the lifting seat plate 1 is driven to lift vertically by a lifting cylinder 13 vertically arranged below the lifting seat plate 1 .

[0024] In this embodiment, a vertically arranged cylindrical protective cover 14 is fixed to the outer peripheral side of the support base plate 6, the bottom of the protective cover 14 is open and is used to cover the outer side of the lifting base plate 1, and a dust suction pipe 15 is connected to the side wall of the protective cover 14, and the dust suction pipe 15 is connected to a vacuum cleaner. Since debris is generated during the polishing process, the vacuum cleaner sucks the debris through the dust suction pipe.
