Description

Technical Field

[0001] This utility model relates to the field of electrical discharge machining (EDM) small hole machine technology, and in particular to an EDM small hole machine with a slider-type moving worktable structure. Background Technology

[0002] Electrical discharge machining (EDM) small hole machines are widely used in many fields such as machining and mold manufacturing, and are used to process high-precision small holes in various materials.

[0003] During the operation of an EDM hole drilling machine, the stability of the moving clamping component plays a crucial role in machining accuracy. Traditional EDM hole drilling machines suffer from numerous stability issues with their moving clamping components. Firstly, common single-slider or simple guide rail structures are prone to shifting and wobbling when subjected to workpiece weight and the discharge impact force during machining. For instance, when machining small holes in large molds, the weight of the workpiece makes it difficult for traditional clamping structures to maintain stability, leading to deviations in the relative positions of the electrode and workpiece during machining. This results in the hole's positional accuracy failing to meet requirements, and fluctuations in hole diameter, severely impacting product quality.

[0004] To address the aforementioned issues, we propose an EDM (Electrical Discharge Machining) machine with a slider-type moving worktable structure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an EDM (Electrical Discharge Machining) machine with a slider-type moving worktable structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An EDM (Electrical Discharge Machining) machine with a slider-type movable worktable structure includes a worktable. A first slide plate and a second slide plate are sequentially arranged on the upper side of the worktable. A clamping assembly is arranged on the upper side of the second slide plate. The clamping assembly includes a rotating cylinder and a fixed column. A clamping groove is fixedly installed on the upper side of the rotating cylinder. The rotating cylinder is rotatably mounted on the upper side of the second slide plate. The fixed column is located inside the rotating cylinder and is fixedly installed on the upper side of the second slide plate. A top cap is fixedly fitted onto the upper end of the fixed column. Three inclined fixing blocks are fixedly installed inside the clamping groove. Clamping blocks are arranged inside the inclined fixing blocks. Telescopic cylinders are fixedly installed between the bottom of each of the three clamping blocks and the top cap. Compression springs are fixedly installed inside the telescopic cylinders.

[0008] Furthermore, a high-torque self-locking motor is fixedly installed on the upper side of the second slide plate, a small gear is fixedly installed on the output end of the high-torque self-locking motor, and a large gear is fixedly installed on the outer wall of the rotating drum, the large gear meshing with the small gear.

[0009] Furthermore, several rollers are rotatably mounted on the outer side of the clamping block, and the rollers are in rolling contact with the inner side of the inclined fixing block.

[0010] Furthermore, a gasket is fixedly installed on the inner side of the clamping block, and the gasket is made of rubber.

[0011] Furthermore, the bottom of the clamping groove is provided with an opening, and the telescopic cylinder is located within the range of the opening.

[0012] Furthermore, a controller and a bracket are fixedly installed on the upper side of the workbench, and an EDM hole puncher is fixedly installed on the side of the bracket.

[0013] Furthermore, the first slide plate is slidably mounted on the upper side of the workbench, and a lower electric telescopic rod is fixedly installed between the first slide plate and the upper side of the workbench. A driven telescopic rod is symmetrically arranged on both sides of the lower electric telescopic rod, and the driven telescopic rod is fixedly installed between the first slide plate and the upper side of the workbench.

[0014] Furthermore, the second slide plate is slidably mounted on the upper side of the first slide plate, and an upper electric telescopic rod is fixedly installed between the side of the second slide plate and the upper side of the first slide plate.

[0015] Compared with related technologies, the EDM hole drilling machine with a slider-type moving worktable structure proposed in this utility model has the following advantages:

[0016] In this invention, an EDM (Electrical Discharge Machining) machine with a slider-type movable worktable structure features a clamping assembly. Three evenly distributed clamping blocks are positioned within the clamping groove of the assembly. When the clamping groove rotates, the clamping blocks are constantly pressed against the inclined fixing block inside the groove by the rebound force of the compression spring. The inclined fixing block rotates synchronously with the clamping groove, causing its inclined surface to abut against the outer surface of the clamping block. This gradually pushes the radial distance between the inner surfaces of the three clamping blocks and the inner side of the clamping groove to change synchronously, thus stably clamping cylindrical workpieces of different specifications. The three clamping blocks, through structural abutment and cooperation, achieve synchronous adjustment of the clamping, ensuring consistent movement steps and improving the clamping stability of the workpiece. This facilitates subsequent drilling accuracy and enhances practicality. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Reference Figures 1-4 An EDM (Electrical Discharge Machining) machine with a slider-type movable worktable structure includes a worktable 1. A first slide plate 5 and a second slide plate 6 are sequentially arranged on the upper side of the worktable 1. A clamping assembly 7 is arranged on the upper side of the second slide plate 6. The clamping assembly 7 includes a rotating cylinder 71 and a fixed column 79. A clamping groove 72 is fixedly installed on the upper side of the rotating cylinder 71. The rotating cylinder 71 is rotatably mounted on the upper side of the second slide plate 6. The fixed column 79 is located inside the rotating cylinder 71 and is fixedly installed on the upper side of the second slide plate 6. A top cap 710 is fixedly sleeved on the upper end of the fixed column 79. Three inclined fixing blocks 76 are fixedly installed inside the clamping groove 72. Clamping blocks 78 are arranged inside the inclined fixing blocks 76. Telescopic cylinders 711 are fixedly installed between the bottom of the three clamping blocks 78 and the top cap 710. A compression spring 712 is fixedly installed inside the telescopic cylinder 711.

[0024] With the above-described configuration, the radial rebound force of the compression spring 712 keeps the clamping block 78 in contact with the inclined surface fixing block 76. When the clamping groove 72 rotates clockwise, the compression spring 712 causes the telescopic cylinder 711 to adaptively drive the clamping block 78 to slide towards the bottom of the inclined surface fixing block 76, thus expanding the clamping area inside the clamping block 78. When the clamping groove 72 rotates counterclockwise, the inclined surface fixing block 76 abuts against the clamping block 78, causing the clamping block 78 to gradually move closer to the inside of the clamping groove 72.

[0025] In this method, a controller 2 and a bracket 3 are fixedly installed on the upper side of the workbench 1, and an EDM hole puncher 4 is fixedly installed on the side of the bracket 3.

[0026] With the above-described setup, the EDM small hole machine 4 is a machine tool that uses the principle of electric spark discharge to process conductive materials. It is a common existing drilling device and will not be described in detail here.

[0027] In this method, the first slide plate 5 is slidably installed on the upper side of the workbench 1. A lower electric telescopic rod 9 is fixedly installed between the first slide plate 5 and the upper side of the workbench 1. A driven telescopic rod 10 is symmetrically arranged on both sides of the lower electric telescopic rod 9. The driven telescopic rod 10 is fixedly installed between the first slide plate 5 and the upper side of the workbench 1. The second slide plate 6 is slidably installed on the upper side of the first slide plate 5. An upper electric telescopic rod 8 is fixedly installed between the side of the second slide plate 6 and the upper side of the first slide plate 5.

[0028] With the above-mentioned setup, when the lower electric telescopic rod 9 is started, it can drive the entire clamping assembly 7 to move back and forth. When the upper electric telescopic rod 8 is started, it can drive the clamping assembly 7 to move left and right. Thus, through the combined action of the lower electric telescopic rod 9 and the upper electric telescopic rod 8, the clamping assembly 7 can drive the workpiece it clamps to adjust its position in the plane. By adjusting its precise position coordinates through the controller 2, precise positioning and drilling work can be achieved.

[0029] In this method, a high-torque self-locking motor 74 is fixedly installed on the upper side of the second slide plate 6, a small gear 75 is fixedly installed on the output end of the high-torque self-locking motor 74, and a large gear 73 is fixedly installed on the outer wall of the rotating drum 71. The large gear 73 meshes with the small gear 75.

[0030] With the above configuration, the high-torque self-locking motor 74 has a self-locking function after stopping. When the high-torque self-locking motor 74 is started, it drives the small gear 75 to mesh with the large gear 73, thereby driving the upper clamping groove 72 to rotate.

[0031] In this configuration, a plurality of rollers 714 are rotatably mounted on the outer side of the clamping block 78, and the rollers 714 are in rolling contact with the inner side of the inclined fixing block 76.

[0032] By setting the roller 714 in the above manner, the frictional loss between the clamping block 78 and the inclined surface fixing block 76 is reduced.

[0033] In this method, a gasket 713 is fixedly installed on the inner side of the clamping block 78, and the gasket 713 is made of rubber.

[0034] By setting the pad 713 in the above manner, the clamping stability of the inner side of the clamping block 78 is improved.

[0035] In this method, the bottom of the clamping groove 72 is provided with a slot 77, and the telescopic cylinder 711 is located within the range of the slot 77.

[0036] By setting it up in the above manner, the slot 77 provides a working area for the telescopic cylinder 711.

[0037] The working principle of the EDM small hole drilling machine with a slider-type moving worktable structure provided by this utility model is as follows:

[0038] When using it, place the cylindrical workpiece to be processed into the clamping groove 72. The high-torque self-locking motor 74 is started, and the output end of the motor drives the pinion 75 to rotate. The pinion 75 meshes with the large gear 73 on the outer wall of the rotating drum 71, driving the rotating drum 71 and the clamping groove 72 fixed on it to rotate. When the clamping groove 72 rotates, the inclined surface fixing block 76 rotates accordingly. Its inclined surface pushes the clamping block 78 to slide along the axial direction of the telescopic drum 711, reducing the clamping area until the three clamping blocks 78 are tightly attached to the surface of the workpiece, completing the stable clamping of the cylindrical workpiece placed inside the clamping groove 72. Through the operation of the controller 2, the extension and retraction of the lower electric telescopic rod 9 and the upper electric telescopic rod 8 are started to achieve precise positioning of the workpiece in the plane, so that the workpiece is in the processing position of the EDM small hole machine 4. After positioning, the EDM small hole machine 4 installed on the side of the bracket 3 is started. The EDM small hole machine 4 uses the principle of electric spark discharge to perform hole drilling on the workpiece. During the processing, the clamping component 7 stably fixes the workpiece to prevent it from being displaced due to the discharge impact force, ensuring the accuracy of the hole drilling.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
