Description

Technical Field

[0001] This utility model relates to the field of slag removal equipment technology, and in particular to a slag removal mechanism for workpiece handles. Background Technology

[0002] After sand casting, hollow tube handles often retain shell film slag impurities inside the handle after mold opening. These impurities need to be cleaned during subsequent workpiece processing. Because the shell film slag residue inside the handle has a certain degree of hardness, it requires manual drilling to remove it by rotating the drill bit. Traditionally, vertical drill bits are used for easy observation of the cleaning process. This results in the inability to collect and treat the shell film dust generated during core drilling, failing to meet environmental dust control requirements. Furthermore, this traditional core drilling process requires a dedicated operator, wasting manpower and impacting production efficiency. Utility Model Content

[0003] This utility model provides a workpiece shank cleaning mechanism, which mainly addresses the shortcomings of traditional vertical drilling machines in cleaning shell film slag during shank machining, such as the inability to collect shell film slag dust in a concentrated manner, resulting in wasted manpower and low efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A slag removal mechanism for a workpiece handle, wherein the handle is a hollow handle with an opening, and includes a workpiece clamping device and a drill spindle. The workpiece clamping device is used to clamp the workpiece and make the workpiece handle coaxial with the drill spindle. When the workpiece is clamped, the opening of the hollow handle faces the horizontal direction, the vertical downward direction, or a direction between the horizontal and the vertical downward direction. The slag removal mechanism also includes a slag collection mechanism disposed at the opening of the hollow handle.

[0006] Furthermore, the workpiece clamping device includes a chuck for contacting the hollow tube handle of the workpiece, and the chuck is provided with a clamping wall surface having multiple contact points with the hollow tube handle.

[0007] Furthermore, the clamping wall surface and the hollow tube handle are in surface contact.

[0008] Furthermore, the clamping wall surface and the hollow tube handle are in point contact.

[0009] Furthermore, the clamping wall surface is in line contact with the hollow tube handle.

[0010] Furthermore, the slag removal mechanism also includes a workpiece sensing device for sensing that the workpiece is being clamped.

[0011] Furthermore, the slag collection mechanism includes a slag collection box and a blower that generates suction to collect the slag.

[0012] Furthermore, the slag collection mechanism also includes a filter plate disposed inside the slag collection box.

[0013] Furthermore, the slag removal mechanism also includes a protective cover covering the opening of the hollow tube handle and the collection port of the slag collection mechanism, the protective cover being used to prevent the slag from spreading during the slag removal process.

[0014] Furthermore, the slag removal mechanism also includes a receiving tray, which is disposed at the workpiece clamping device and is used to receive the workpiece after slag removal.

[0015] The beneficial effects of this utility model are as follows:

[0016] When the drill shaft drills sand cores into the inner shell membrane slag of the hollow tube handle, the opening of the hollow tube handle faces horizontally, vertically downward, or in a direction between horizontal and vertically downward, so that the sand core dust can be discharged in a timely and concentrated manner into the slag collection mechanism.

[0017] Through the automated linkage design of the workpiece clamping device and the drill spindle, the workpiece sensing device senses the workpiece clamping device holding the workpiece fed by the robot arm, and then instructs the drill spindle to perform core drilling. After the slag removal is completed, the workpiece clamping device releases its clamping action on the workpiece, the workpiece is removed from the workpiece clamping device, and the next workpiece is fed by the robot arm. This fully automates the workpiece handle slag removal process, improves production efficiency, and saves labor costs. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the slag removal mechanism for the workpiece tube handle described in Example 1. Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] One such Figure 1The workpiece slag removal mechanism shown has a hollow tube handle with an opening. In this embodiment, the workpiece is a golf club head blank. The golf club head includes a handle and a striking face. The handle is the neck, used to install the shaft for the golfer to hold; therefore, the handle is hollow. The slag removal mechanism includes a workpiece clamping device 1, a drill spindle 2, and an electrical control system. The workpiece clamping device 1 clamps the workpiece and makes the workpiece handle coaxial with the drill spindle 2. The electrical control system controls the operation of the slag removal mechanism. When the workpiece is clamped, the opening of the hollow tube handle faces horizontally, vertically downward, or a direction between horizontal and vertically downward. In this embodiment, the hollow tube handle opening is preferably horizontal, meaning the drill spindle 2 is horizontal. This facilitates rapid cleaning of the inner shell membrane slag of the hollow tube handle without affecting its service life. The slag removal mechanism also includes a slag collection mechanism 3 located at the opening of the hollow tube handle. The drill spindle 2 drills out the inner shell membrane slag of the hollow tube handle, and the membrane slag is automatically or passively collected into the slag collection mechanism 3.

[0022] The aforementioned drill spindle 2 is a machining component of a horizontal drilling machine, which includes a drilling motor and a drilling stroke adjustment platform, etc. The stroke of the drill spindle is preset for a specific workpiece.

[0023] The workpiece clamping device includes two chucks 11 for contacting the outer periphery of the hollow tube handle of the workpiece. Each chuck 11 has a clamping wall surface with multiple contact points with the hollow tube handle. The clamping force of the chucks 11 on the workpiece is sufficient to prevent the workpiece from moving or rotating when the shell film slag is removed.

[0024] In this embodiment, the clamping wall of the chuck 11 is in surface contact with the hollow tube handle. For a golf club head, the hollow tube handle is cylindrical, and the clamping wall is an arc-shaped wall that fits the outer circumference of the cylindrical tube handle. The arc-shaped wall has a large contact area with the hollow tube handle, providing good coverage and better facilitating the cleaning of the hollow tube handle by the drill spindle.

[0025] like Figure 1 As shown, the slag removal mechanism also includes a workpiece sensing device 4 for sensing that the workpiece is clamped by the workpiece clamping device 1. The workpiece sensing device 4 can be a conventional sensor, an infrared beam sensor, etc. The workpiece sensing device 4 is set on the workpiece clamping device 1. When it senses that the workpiece is clamped, the signal is fed back to the electronic control system, which then controls the drill spindle 2 to advance to drill the sand core of the workpiece.

[0026] With the workpiece clamping device as the boundary, on the side opposite to the drill spindle 2, the slag removal mechanism is also equipped with a receiving tray 5. The receiving tray 5 is set close to the workpiece clamping device 1 and is used to receive the workpiece after slag removal. When the hollow tube shank is finished drilling the sand core, the workpiece clamping device 1 will release its grip on the workpiece, and the workpiece will fall into the receiving tray 5 due to the shift of the center of gravity.

[0027] like Figure 1 As shown, the slag collection mechanism 3 includes a slag collection box 31 and a fan that generates suction to collect the slag. The fan is located inside the slag collection box 31, which has a vertically oriented collection port. The slag collection box 31 also contains a filter plate to filter out non-dust-laden membrane slag. The bottom of the slag collection box 31 has a removable drawer structure 32 for easy cleaning after a certain amount of membrane slag dust has accumulated. The drawer structure 32 is generally filled with water for dust sedimentation. A dust extraction duct interface can also be connected to the slag collection box 31, which can be connected to dust treatment equipment for timely treatment of accumulated dust.

[0028] The slag removal mechanism also includes a protective cover 6 covering the opening of the hollow tube handle and the collection port of the slag collection mechanism. The protective cover 6 is preferably an arched cover. The protective cover 6 is used to prevent the slag from spreading during the slag removal process and to avoid dust affecting the working space environment.

[0029] This embodiment's slag removal mechanism integrates automatic core drilling and dust treatment functions. Through the automated linkage design of the workpiece clamping device and the drill spindle, the workpiece sensing device detects the workpiece clamping device's gripping of the workpiece fed by the robotic arm, thereby instructing the drill spindle to perform core drilling. After slag removal is completed, the workpiece clamping device releases its gripping action on the workpiece, and the workpiece detaches from the workpiece clamping device, allowing the next workpiece to be fed in by the robotic arm. This fully automates the workpiece handle slag removal process. The specific operation can be performed by the personnel in the previous process of workpiece processing, significantly improving production efficiency and saving labor costs. When the drill spindle drills cores for the inner shell membrane slag of the hollow tube handle, the core drilling dust can be collected in a timely and concentrated manner into the slag collection mechanism, achieving the purpose of centralized dust collection and treatment.

[0030] The overall working process of the slag removal mechanism is as follows: When the workpiece is transferred to the workpiece clamping device by the robotic arm, the workpiece sensing device outputs a signal, and the electrical control system controls the workpiece clamping device to hold the handle. The drill spindle of the horizontal drilling machine moves along the fixed axial stroke direction. When the set stroke is reached, the drill spindle stops moving forward and returns to the origin. The electrical control system controls the workpiece clamping device to release the workpiece, and the workpiece falls into the receiving tray. Subsequent workpiece placement can be repeated. During the movement of the drill spindle, the fan of the slag collection mechanism starts, so that the drill core dust is collected into the drawer structure.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that the clamping wall of the chuck is in line contact with the hollow tube handle, that is, the cross-section formed after the two chucks come together is a polygonal structure with an inscribed circle. It is sufficient to ensure that the inscribed circle is adapted to the outer circumference of the hollow tube handle. The cross-sectional structure of the chuck is consistent in all parts of the axial direction.

[0033] This line contact method between the clamping wall and the hollow shaft offers comparable clamping stability to surface contact, and it is more compatible, accommodating golf club heads with hollow shafts of varying sizes. However, line contact may be limited by the materials chosen for the chuck and the hollow shaft. If the chuck material is more rigid than the hollow shaft, scratches may appear on the shaft.

[0034] Example 3

[0035] The difference between this embodiment and embodiment 2 is that the clamping wall of the chuck is in point contact with the hollow tube handle, that is, there is only one section in the axial direction of the chuck that is in contact with the hollow tube handle.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
