Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a bolt hole machining device for mold machining. Background Technology

[0002] Bolt hole machining equipment for mold machining is mainly used to efficiently and accurately machine bolt holes on molds. It achieves internal thread machining through thread forming technology. It has a compact structure and low cost, and is suitable for bolt hole machining scenarios of various molds, especially industrial scenarios that require high precision and mass production.

[0003] Chinese patent CN212398218U discloses a bolt hole processing device for mold machining. The device includes a base plate with a damper detachably connected to its upper end. A bracket is detachably connected to the upper end of the damper. A stepper motor drives a transmission shaft to rotate, which in turn drives a lead screw to rotate via a coupling. The lead screw performs a threaded feed motion along the inner wall of the lead screw sleeve. Sliders on both sides of the lead screw sleeve slide down a groove track on a limiting plate that matches the end of the slider, thereby driving a U-shaped plate and a processing head connected to its lower end to process bolt holes in the mold. The overall structure is simple and low-cost. The vibration waves generated by the stepper motor during operation are transmitted to the damper through the bottom of the bracket. The external spring of the damper undergoes expansion and contraction deformation, and its amplitude provides shock absorption for the entire device. This device is suitable for widespread promotion and use.

[0004] Cutting fluid is usually added to the surface of bolt hole machining equipment. During the operation of the drilling equipment, a large amount of waste chips are generated. These waste chips may splash into the inside of the cutting fluid addition equipment, which can easily cause blockage at the bottom of the addition structure, thereby affecting the effect and uniformity of cutting fluid addition, and thus affecting the effect of mechanical drilling of molds. Utility Model Content

[0005] The purpose of this invention is to provide a bolt hole processing device for mold machining, in order to solve the problem mentioned in the background art that waste chips may splash into the inside of the cutting fluid addition equipment, which can easily cause blockage at the bottom of the addition structure, thereby affecting the effect and uniformity of cutting fluid addition.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bolt hole processing device for mold machining, comprising a hole opening component fixedly installed on the top of the processing table, an injection anti-clogging component provided at the outer end of the hole opening component, a placement plate fixedly installed on the top of the processing table, and a precision depth component provided on one side of the hole opening component;

[0007] Preferably, the liquid injection anti-clogging component includes a liquid injection tank, which is fixedly installed at the bottom of the protective cylinder. The bottom of the liquid injection tank has multiple liquid injection ports. A drive motor is fixedly installed on one side of the liquid injection tank. A small gear is fixedly installed at the output end of the drive motor. A large gear is meshed with one side of the small gear. A protective ring is fixedly installed inside the large gear.

[0008] Preferably, the hole-opening assembly includes an adjustable support frame, which is fixedly installed on the top of the processing table. An electric slide rail is fixedly installed on one side of the adjustable support frame. A track block is slidably connected to the outer end of the electric slide rail. A control box is fixedly installed on one side of the track block. A protective cylinder is fixedly installed at the bottom of the control box. A hole opener is rotatably connected inside the protective cylinder.

[0009] Preferably, the precision depth component includes a scale, which is fixedly installed on one side of the adjustment support frame, and a lower clamp is slidably connected to the outer end of the scale. A laser emitter is fixedly installed on one side of the control box.

[0010] Preferably, a pointer is fixedly installed on one side of the lower clamp, an upper clamp is slidably connected to the outer end of the scale, and a laser receiver is fixedly installed on one side of the upper clamp.

[0011] Preferably, the injection tank is located at the bottom of the protective cylinder, and the injection port is slidably connected to the protective ring.

[0012] Preferably, the control box is electrically connected to the hole opener, and the electric slide rail is electrically connected to the control box.

[0013] Preferably, the laser emitter is electrically connected to the control box, and the lower clamp and the upper clamp have the same structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a liquid injection anti-clogging component, the liquid injection port adds cutting fluid to the drill bit at the bottom of the hole opener, reducing friction between the drill bit and the hole wall, extending tool life and improving surface quality. With the cooperation of small gear, large gear and protective ring, the inside of the liquid injection port can be protected when liquid injection is not needed, preventing cutting debris from entering the liquid injection port and causing blockage. At the same time, the rotation design of the protective ring can automatically adjust the opening and closing according to the working status of the hole opener, ensuring the accuracy and continuity of the liquid injection process.

[0016] 2. By setting a precision depth component, the scale provides a reference for the sliding of the lower and upper clamps, and the pointer can intuitively indicate the position of the lower clamp. The laser emitter and laser receiver work together. When the lower clamp moves with the workpiece to the set depth, the laser receiver receives the laser signal and feeds it back to the control box. The control box then controls the electric slide rail to stop running, thereby achieving precise control of the bolt hole machining depth and effectively improving machining accuracy.

[0023] 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.

[0024] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 This utility model provides a technical solution: a bolt hole processing device for mold machining, including a hole opening component fixedly installed on the top of the processing table 1, an injection anti-blocking component provided at the outer end of the hole opening component, and a placement plate 4 fixedly installed on the top of the processing table 1.

[0025] The fluid injection anti-clogging component includes a fluid injection tank 31, which is fixedly installed at the bottom of the protective cylinder 25. Multiple fluid injection ports 32 are provided at the bottom of the fluid injection tank 31. A drive motor 33 is fixedly installed on one side of the fluid injection tank 31. A pinion gear 34 is fixedly installed at the output end of the drive motor 33. A large gear 35 is meshed with one side of the pinion gear 34. A protective ring 36 is fixedly installed inside the large gear 35. The uniform supply of cutting fluid can be achieved through the sliding connection between the fluid injection ports 32 and the protective ring 36, further optimizing the chip removal effect during bolt hole machining, reducing machining errors caused by chip accumulation, and ensuring the dimensional accuracy and machining efficiency of the bolt holes. The hole-opening component includes an adjusting support frame 21, which is fixedly installed on the top of the machining table 1. An electric slide rail 2 is fixedly installed on one side of the adjusting support frame 21. 2. The outer end of the electric slide rail 22 is slidably connected to a track block 23. A control box 24 is fixedly installed on one side of the track block 23. A protective cylinder 25 is fixedly installed at the bottom of the control box 24. An opening device 26 is rotatably connected inside the protective cylinder 25. The liquid injection tank 31 is located at the bottom of the protective cylinder 25. The liquid injection port 32 is slidably connected to the protective ring 36. The control box 24 is electrically connected to the opening device 26. The electric slide rail 22 is electrically connected to the control box 24. The adjusting support frame 21 provides stable support for the electric slide rail 22. The electric slide rail 22 drives the track block 23 and the control box 24 to realize the up and down movement of the opening device 26 to meet the processing requirements of different depths. The protective cylinder 25 can protect the opening device 26 during the opening process, avoid damage to the equipment caused by flying debris during processing, and also ensure the safety of the operator.

[0026] Please see Figure 1 , Figure 2 and Figure 3 A precision depth component is provided on one side of the opening assembly. The precision depth component includes a scale 51, which is fixedly installed on one side of the adjusting support frame 21. The outer end of the scale 51 is slidably connected to a lower clamp 52. A laser emitter 56 is fixedly installed on one side of the control box 24. A pointer 53 is fixedly installed on one side of the lower clamp 52.

This retains the intuitiveness of the traditional scale 51 and realizes automated depth monitoring through real-time transmission of laser signals, avoiding errors that may occur from manual observation. At the same time, the consistent structural design of the lower clamp 52 and the upper clamp 54 ensures stability during the sliding process, so that the depth control can maintain a high consistency in repeated processing, further improving the overall processing reliability of the device.

[0027] Working principle: The operator fixes and limits the mold machine above the placement plate 4, adjusts the position of the lower clamp 52 so that the pointer 53 is level with the top of the mold machine, and then adjusts the upper clamp 54. The upper clamp 54 will drive the laser receiver 55 to adjust, and adjust the laser receiver 55 to the scale of the required drilling depth.

[0028] Cutting fluid is delivered from inside the injection tank 31 to the drill bit surface at the bottom of the hole opener 26 to add cutting fluid to the drill bit surface. After the addition is completed, the drive motor 33 is started. The drive motor 33 drives the pinion 34 to rotate, the pinion 34 drives the large gear 35 to rotate, and the large gear 35 drives the protective ring 36. The protective ring 36 protects the injection port 32.

[0029] Subsequently, the hole opener 26 is activated, and the drill bit at the bottom of the hole opener 26 drills bolt holes on the mechanical surface of the mold. The electric slide rail 22 is activated, and the electric slide rail 22 drives the track block 23 to adjust downward. The track block 23 drives the control box 24, and the control box 24 drives the hole opener 26 to adjust downward, thereby adjusting the hole opening depth of the hole opener 26. At the same time, the control box 24 drives the laser emitter 56, and the laser emitted by the laser emitter 56 is received by the laser receiver 55. The laser receiver 55 transmits the signal to the control box 24, and the control box 24 controls the equipment to stop drilling. The above is the working process of the entire device.
