The present invention relates to a device for removing burrs from die-casting products. Specifically, when an operator sequentially clamps a die-casting product to a plurality of clamping means installed radially on a turntable, the turntable rotates to move the die-casting product step by step, and the clamping means While the die-casting product is rotated 360°, the height of the burr formed on the edge of the die-casting product is recognized using a 3D scanner. When the die-casting product is moved in front of the polishing means, the polishing means moves forward and backward according to the height of the burr recognized by the vision camera, and the clamping means It relates to a burr removal device for die-casting products that reduces work time and allows precise burr removal by removing burrs from die-casting products that are rotated 360°.

In general, golf is a sports game in which a golf ball called a golf club is used to hit a golf ball into a hole cup at a certain distance, and unlike other sports, it requires considerably high accuracy and mental strength. Additionally, in golf, unlike other sports, the direction and distance of the hit may depend on the golfer's shot posture, swing form, and grip state. Golf clubs are broadly divided into three types: drivers for increasing distance, irons for precise shots, and putters for hitting the golf ball on the green. Most are made of titanium. Manufactured from high-strength metal.

In particular, in the case of driver clubs, human factors such as posture and speed and repulsion force depending on the material or characteristics of the driver club play an important role in increasing the distance.

The heads of these golf clubs are made of various materials such as ferrous metal alloys, non-ferrous metal alloys, titanium alloys, aluminum alloys, zinc alloys, etc.

Recently, aluminum alloy containing zinc has been used as the metal that constitutes the golf club head, and is manufactured by a die casting method.

The head of a golf club manufactured by the die casting method is manufactured by a die casting mold that presses molten metal into the cavity through a runner (passage) connecting the sprue and the cavity and then cools the molten resin to demold the casting.

In die cast castings produced by the die casting method, runners, overflows, push pins, etc. remain, and it is difficult to avoid the phenomenon of burrs, residues of molten metal, sticking to most push pins.

Runners and overflows remaining in die cast castings must be removed anyway, and in the case of products that require precision, burrs attached to the push pin must be removed. In the case of runners and overflows, such as press molds, etc. Equipment was used to cut and remove the necessary burrs, but in the case of burrs formed on the mill pin, the grinding (removal) work was dependent on manual work, which inevitably resulted in an increase in the number of processes and time, as well as an increase in cost due to the requirement of manpower.

In addition, in some cases, the push pin is formed close to the die cast product, and in this case, the removal of the burr attached to the push pin must be done more precisely, so there is a problem that the work time is inevitably increased. It is being pointed out.

In order to solve this problem, a chamfering device for removing burrs from round products, published in Domestic Patent Publication No. 10-054954, has been published.

The chamfering device for removing burrs from a circular product is a chamfering device for removing burrs from a circular product that chamfers burrs of a product using a cutting tool, as shown in FIGS. 1 and 2. The product to be chamfered (104) A driving jig 110 provided with a structure that can be driven in a shape that can be seated in a horizontal state and can be partially exchanged; The driving jig presses the upper surface of the product 104, which is maintained in a state of being seated on the driving jig 110, so that the product 104 to be chamfered is chucked between the driving jig 110 and the driving jig 110. A lifting jig (120) that is operable to be driven at the upper position of the driving jig (110) corresponding to (110); A driving means connected to the driving jig 110 through a power transmission device and positioned at a lower position of the driving jig 110 so as to drive the driving jig 110; Elevating means mounted on the upper frame (F2) in a structure that couples the lifting jig 120 to the rod end so that the lifting jig 120 can be raised and lowered by the lifting jig cylinder 180. class; a tool rest (150) fixed to the frame (F) at a height corresponding to the product (104) chucked between the driving jig (110) and the lifting jig (120); It includes a controller (C) that controls the operation of the driving means, the lifting means, and the tool post 150.

However, in the chamfering device for removing burrs from circular products according to the prior art, when an operator places one product, it chuks it and then rotates to remove the burr, removes the product, and then performs the above operation again, so the work time is relatively short. There is a problem in that it is difficult to reduce the time and cost required for production because it takes a long time.

Referring to Figures 3 and 5, the device for removing burrs from die casting products according to the present invention (1) includes a turntable (10), a clamping means (20), a rotary cylinder (30), a 3D scanner (40), It includes a polishing means (50) and a dust collecting means (60).

First, the turntable 10 rotates an equal angle step by step by the main servo motor 11. For example, when four clamping means 20 are provided, the turntable 10 rotates by 90°, and when eight clamping means are provided, it rotates by 35°.

The turntable 10 is equipped with a clamping means 20, which will be described below, at the center of the upper surface, and a rotary joint 13 to supply pneumatic pressure to the rotary cylinder 30 and prevent the pneumatic line from being twisted.

Additionally, the clamping means 20 is installed radially and vertically around the rotation axis on the turntable 10 and is installed to rotate on its own by the bearing B. At this time, the clamping means 20 are installed at equal angles, that is, at every 90° position when four clamping means 20 are provided.

The clamping means 20 is installed at a fixed height and spaced apart from the pedestal 21 on which the die-casting product (D) is seated, and on the same line as the pedestal 21, and fixes the die-casting product (D) while moving up and down, and pneumatically It consists of a raised and lowered actuator (23) that operates.

The die casting product (D) is fixed to the end of the pedestal 21 and the lifting and lowering actuator 23, and the first and second plates 25 and 27 are formed in a plate shape with a size that does not interfere with the polishing means 50. , It is preferable that projections or grooves are formed on the first and second plates (25, 27) to be inserted into the bolt holes and projections provided on the upper and lower surfaces of the die casting product (D), and are made of rubber or synthetic resin to suppress vibration generation. An anti-vibration pad 29 may be provided.

The pedestal 21 is equipped with an optical sensor (S) to check whether the die casting product (D) is seated.

The second plate 27 of the raising and lowering actuator 23 is rotated by the bearing B to rotate the die casting product D according to the rotation of the pedestal 21.

In addition, the rotary cylinder 30 is installed on the bottom of the turntable 10 at the lower part of the pedestal 21 of the clamping means 20 and rotates each clamping means 20 360° forward and backward. At this time, the rotary cylinder 30 is operated by pneumatics, and it is preferable that the rack and pinion type is applied.

The rotary cylinder 30 rotates the die casting product D by rotating the base 21 of the clamping means 20 by 360° at the position of the 3D scanner 40 and then rotates it to its original position before moving to the polishing means 50.

The rotary cylinder 30 rotates the clamping means 20 by 360° at the position of the polishing means 50, and when polishing of the die-casting product (D) is completed, it rotates the die-casting product (D) by 360° in the opposite direction before moving to the discharge position. I order it.

In addition, the 3D scanner 40 is installed spaced apart on one side of the turntable 10 (for example, if the input position is 0° and the discharge position is 270°, it is installed at a 90° position) so that the die casting product (D) moves. After being positioned, the clamping means (20) is rotated 360° by the rotary cylinder (30), and the die casting product (D) is scanned to measure the height of the burr.

Next, the polishing means 50 is a grinder, which is installed at a distance from the other side of the turntable 10 (installed at a 180° position), and when the die casting product D is moved and positioned, it is advanced by the forward and backward actuator 51. When the clamping means 20 is rotated 360° by the rotary cylinder 30, the burr is polished by moving forward and backward according to the height of the burr of the die casting product D measured by the 3D scanner 40. At this time, the polishing means 50 is equipped with an optical sensor (S) to measure the distance from the die casting product (D).

Subsequently, the dust collecting means 60 sucks in and discharges the burs that are polished and scattered by the polishing means 50 through the blowing fan 61 and the duct 63.

Hereinafter, the operation of the device for removing burrs from die casting products according to the present invention will be described in detail with reference to the attached drawings.

Referring to FIG. 6, when the operator first places the die casting product (D) in the correct position on the first plate (25) provided at the end of the pedestal (21) of the clamping means (20), the optical sensor (S) confirms this. Then, the second plate 27 of the raising and lowering actuator 23 is lowered and fixed while applying pressure to the die casting product (D).

When the die casting product (D) is fixed, the turntable (10) rotates 90° by the main servo motor (11) and then stops. When the turntable 10 is rotated and stopped, the worker fixes the die casting product D to the clamping means 20 through the above process again.

At the same time, the rotary cylinder 30 rotates the base of the clamping means 20 located at 90° 360°, and the 3D scanner 40 scans the die casting product D to measure the height of the burr.

When scanning of the die casting product (D) is completed, the turntable (10) is again rotated by 90° by the main servo motor (11) and stopped at the position of the polishing means (50). At this time, the rotary cylinder 30 rotates the die casting product D by rotating the stand 21 360° at the position of the 3D scanner 40 and then rotates it to its original position before moving to the polishing means 50.

When the die casting product (D) is moved forward and stopped by the polishing means (50), the polishing means (50) is advanced by the optical sensor (S) and the forward and backward actuator (51) in a state in contact with the side of the die casting product (D). When the stand 21 is rotated 360° by the rotary cylinder 30, the burr is polished by moving forward and backward according to the height of the burr formed on the side of the die casting product (D) measured by the 3D scanner 40.

When polishing of the bur is completed, the polishing means 50 returns to the original position, and then the turntable 10 is rotated 90° by the main servo motor 11 and moves to the discharge position, and at the discharge position, the lifting and lowering actuator ( When 23) rises, the operator removes the die casting product (D).

Afterwards, the clamping means 20 is rotated to its initial position and the above process is repeated.

Therefore, according to the present invention, work time can be shortened by processing burrs while rotating a plurality of die casting products on a turntable.
