Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a device for measuring the conical surface of a venting screw during drilling. Background Technology

[0002] As a common type of fastener, the vent screw requires drilling and inspection of the conical surface during its processing. Traditional processing methods typically employ a multi-stage processing approach, which is inefficient and prone to errors.

[0003] Currently, most processing equipment on the market is single-machine operation, requiring manual loading, inspection, and sorting, which is not only time-consuming and labor-intensive but also carries the risk of missed inspections. Traditional conical drilling equipment has a processing cycle of 1 piece / 30 seconds, and can only be manually processed by one person with one machine, which cannot meet the needs of modern high-efficiency production. In addition, traditional conical surface measurement requires the use of a separate pneumatic gauge with tooling for manual inspection, which is cumbersome and prone to missed inspections, affecting production efficiency and product quality. Furthermore, the traditional two-stage drilling sequence, which involves processing and inspecting the conical surface twice, may result in wasted time during transfer and transportation, or errors or omissions during processing.

[0004] Therefore, there is an urgent need to develop a new type of venting screw processing equipment that can achieve efficient synchronous drilling, automatic detection of conical surfaces, and sorting of qualified and unqualified products, thereby improving production efficiency and product quality. Summary of the Invention

[0005] The purpose of this invention is to provide a device for drilling and measuring the conical surface of vent screws, which realizes efficient processing and inspection of vent screws. It can complete simultaneous drilling of two holes and automatic inspection of the conical surface within one processing cycle, solving the problem of low efficiency of traditional manual single-machine operation.

[0006] The present invention is achieved through the following technical solution.

[0007] The present invention provides a device for drilling and measuring the conical surface of a venting screw, comprising:

[0008] Loading module: The loading module is used to transfer the workpiece to the processing and inspection station;

[0009] The processing module includes a deep hole drilling assembly, a side hole drilling assembly, a caliper assembly, and an air blowing nozzle. The caliper assembly is used to clamp and fix the workpiece at the processing and inspection station. The deep hole drilling assembly and the side hole drilling assembly are used to perform deep hole and side hole drilling on the fixed workpiece, respectively. The air blowing nozzle is used to blow the workpiece away from the processing and inspection station.

[0010] Conical surface inspection module: includes an inspection head and an inspection device lifting drive. The inspection device lifting drive is used to drive the inspection head to move. When the workpiece is located at the processing inspection station, the inspection device lifting drive drives the inspection head to move towards the workpiece so that the conical surface of the workpiece is inserted into the inspection head. During inspection, air is injected into the inspection head, and the airtightness of the inspection head is tested to determine whether the conical surface is qualified.

[0011] Sorting module: includes qualified product flow channel, unqualified product flow channel, plate body and plate body driving assembly. The qualified product flow channel is provided with sorting holes, and the workpiece can enter the unqualified product flow channel through the through holes. The plate body is connected to the plate body driving assembly, which is used to drive the plate body to move and open and close the sorting holes.

[0012] When the conical surface detection module detects that the conical surface of the workpiece is unqualified, the air nozzle blows the workpiece away from the processing and inspection station. The workpiece is transferred to the qualified product flow channel and moves along the qualified product flow channel. The plate body drive assembly drives the plate body to move, causing the sorting hole to open. The workpiece is transferred from the sorting hole to the unqualified product flow channel and discharged.

[0013] When the conical surface inspection module detects that the conical surface of the workpiece is qualified, the deep hole drilling assembly and the side hole drilling assembly process the workpiece. After processing, the air blowing nozzle blows the workpiece away from the processing and inspection station, and the workpiece is transferred to the qualified product flow channel and discharged along the qualified product flow channel.

[0014] By integrating the conical surface detection module with the processing module, the detection results are judged in real time by the control system. Defective products enter the defective product outlet through the air-blowing slide, while qualified products enter the next processing step. The dual-station synchronous drilling mechanism realizes the synchronous processing of the two holes of the venting screw, and the sorting module realizes the automatic separation of qualified and defective products. These technological innovations have significantly improved the processing efficiency of the equipment, while ensuring processing quality and detection reliability, reducing the need for manual intervention, and making it particularly suitable for the processing needs of large batches and high precision venting screws.

[0015] Furthermore, the feeding module includes a vibratory feeder, a product flow channel, and a support base. The support base is located at the processing and inspection station, and the support base is provided with positioning holes for positioning workpieces. When inspecting the workpiece, the inspection head is located in the positioning holes.

[0016] Furthermore, the processing module also includes a cutting fluid nozzle, which is used to spray cutting fluid during the workpiece drilling process for cooling during drilling.

[0017] Furthermore, before the workpiece reaches the processing and inspection station, the air nozzle blows air to clean the processing and inspection station, removing the chips and facilitating subsequent processing.

[0018] Furthermore, the caliper assembly includes a caliper and a caliper drive assembly. Two sets of calipers are provided and symmetrically arranged on both sides of the processing and inspection station. The contact position between the caliper and the workpiece is a contour structure. The caliper drive assembly is used to drive the caliper to move. The two sets of calipers arranged in front and behind each other fix the workpiece. The fixed workpiece is then inspected and drilled.

[0019] Furthermore, both the qualified product flow channel and the unqualified product flow channel are inclined, using gravity to achieve product sorting. The unqualified product flow channel is located below the qualified product flow channel, resulting in a simple structure and low cost.

[0020] Furthermore, the extension directions of the qualified product flow channel and the unqualified product flow channel are arranged in an intersecting manner, so that the flow directions of qualified products and unqualified products are staggered, making them easy to distinguish.

[0021] Furthermore, when the conical surface detection module detects that the conical surface of the workpiece is qualified, the detection device lifts and drives the detection head to move and disengage from the conical surface of the workpiece, and then the workpiece is drilled.

[0022] After the detection head moves and disengages from the workpiece's conical surface, the workpiece's conical surface remains within the positioning hole, ensuring the stability of the machining process. This also prevents workpiece vibration during machining from causing wear and other effects on the detection head, thus ensuring the detection head's accuracy and service life.

[0023] Furthermore, a sealing door is provided in the positioning hole. After the detection head is separated from the workpiece conical surface, the sealing door is located between the detection head and the workpiece and is closed. The sealing door can prevent chips and cutting fluid from entering the detection head.

[0024] Furthermore, the closed door includes two sets of door panels disposed in positioning holes. The door panels are installed by spring hinges, and the door panels are opened when the detection head moves toward the conical surface of the workpiece.

[0025] Alternatively, the closed door can also be a sliding door panel, driven by a linear module such as a cylinder to achieve the opening and closing effect.

[0026] Furthermore, the conical surface detection module also includes a detection device body and a detection device mounting frame. The detection device body is movably mounted on the detection device mounting frame to ensure lifting stability.

[0027] The beneficial effects of this invention are as follows: By setting up a feeding module, a processing module, a sorting module, and a conical surface detection module, simultaneous drilling of two holes and automatic detection of the conical surface can be completed within one processing cycle. When the workpiece arrives at the processing position, the conical surface detection module detects the conical surface, and unqualified products are discharged. Only qualified products enter the next drilling process, thus integrating the conical surface detection and hole processing in the same position, eliminating the need for transfer transportation. The sorting module realizes the automatic separation of qualified and unqualified products. The above effects combined significantly improve the processing efficiency of the equipment, shortening the cycle time to 5 seconds / piece, while ensuring processing quality and detection reliability, reducing the need for manual intervention, and making it particularly suitable for the processing needs of large batches and high precision venting screws.

Detailed Implementation

[0039] The following is combined with Figures 1-8 The present invention will be described in detail below.

[0040] Example 1:

[0041] The present invention provides a device for measuring the conical surface of a venting screw during drilling, such as... Figure 1 It includes a frame 4, a feeding module 1, a processing module 2, a sorting module 3, and a conical surface detection module 6. The feeding module 1, the processing module 2, the sorting module 3, and the conical surface detection module 6 are all set in the frame 4, and doors are set on the front and rear sides of the frame 4.

[0042] In this embodiment, the frame 4 is welded from No. 45 steel and coated with anti-rust paint.

[0043] like Figure 2 The feeding module 1 is used to transfer the workpiece to the processing and inspection station. The feeding module 1 includes a vibratory feeder 11, a product flow channel 12 and a support base 13. One end of the product flow channel 12 is connected to the outlet of the vibratory feeder 11, and the other end extends to the processing and inspection station with an inclination angle of 15°. The product flow channel 12 is connected to the vibrator 14 and the material is conveyed by vibration. The support base 13 is located at the bottom of the product flow channel 12, which is the processing and inspection station. The support base 13 is provided with a positioning hole 15. The workpiece is conveyed to the positioning hole 15 through the product flow channel 12. The conical surface of the workpiece enters the positioning hole 15. When the workpiece is inspected, the inspection head 61 is located in the positioning hole 15.

[0044] The vibratory feeder is preferably made of 304 stainless steel with a diameter of 300mm, and has an internal spiral track. The vibration frequency is adjustable from 50-100Hz. The vibrator is an electromagnetic vibrator with a power of 100W.

[0045] like Figure 2 , Figure 4 The machining module 2 includes a deep hole drilling assembly 21, a side hole drilling assembly 22, a caliper assembly, an air blowing nozzle 24, and a cutting fluid nozzle 25.

[0046] The deep hole drilling assembly 21 and the side hole drilling assembly 22 can be any drilling mechanism in the prior art. In this embodiment, both the deep hole drilling assembly 21 and the side hole drilling assembly 22 include a drill bit, a drill bit sleeve, a spindle for driving the drill bit to rotate, and a feed mechanism. The feed mechanism is preferably an electric cylinder lift, and the SMC MGP series is selected with a stroke of 200mm.

[0047] The deep small hole drill bit sleeve is made of cemented carbide, with an inner diameter of 3mm, and is installed at the lower end of the electric cylinder lifter. The side hole cylinder and drill bit sleeve use SMC's CDQ2B series cylinders, with a stroke of 50mm and an inner diameter of 2.5mm for the drill bit sleeve.

[0048] This equipment processes workpieces such as air release screws (5). Figure 8 The vent screw 5 needs to be machined with a deep hole 51 and a side hole 52, and the conical surface 53 needs to be inspected. The deep hole drilling assembly 21 is used to machine the deep hole 51, and the side hole drilling assembly 22 is used to machine the side hole 52.

[0049] The caliper assembly is used to clamp and fix the workpiece at the machining and inspection station. The deep hole drilling assembly 21 and the side hole drilling assembly 22 are used to perform deep hole and side hole drilling on the fixed workpiece, respectively. Figure 3 , Figure 4 The caliper assembly includes calipers 23 and a caliper drive assembly. Two sets of calipers 23 are symmetrically arranged on both sides of the processing and inspection station. The contact position between the calipers 23 and the workpiece is a contour structure. In this embodiment, the calipers 23 contact the hexagonal nut of the vent screw 5. The caliper drive assembly is used to drive the calipers 23 to move. The caliper drive assembly uses two sets of caliper drive cylinders 26. The two sets of calipers 23 arranged in front and behind each other fix the workpiece. The fixed workpiece is then inspected and drilled.

[0050] The air nozzle 24 is used to blow the workpiece away from the processing and inspection station, and to clean the station. Before the workpiece arrives at the processing and inspection station, the air nozzle 24 blows air to clean the processing and inspection station, removing the chips at the processing and inspection station to facilitate subsequent processing.

[0051] The cutting fluid nozzle 25 is used to spray cutting fluid during the drilling process of the workpiece for cooling during the drilling process.

[0052] The cutting fluid nozzle is made of stainless steel with a nozzle diameter of 1mm and an adjustable flow rate of 10-50ml / min. The gas blowing nozzle is made of copper with a nozzle diameter of 2mm and an adjustable air pressure range of 0.2-0.5MPa.

[0053] like Figure 4 , Figure 5The conical surface detection module 6 includes a detection head 61, a detection device body 62, and a detection device lifting drive 63. The detection device lifting drive 63 is preferably a cylinder, but a lead screw linear module can also be used. The detection device lifting drive 63 is used to drive the detection head 61 to move up and down in the positioning hole 15. The detection device body 62 is movably mounted on the detection device mounting bracket 64 via a slide rail to ensure lifting stability.

[0054] The inspection head 61 is located at the processing and inspection station. The conical surface of the workpiece can be inserted into the inspection head 61. During inspection, air is injected into the inspection head 61, and the airtightness of the inspection head 61 is tested to determine whether the conical surface is qualified.

[0055] When the workpiece reaches the processing position, the photoelectric sensor set at the processing and inspection station triggers the positioning signal. The lifting drive 63 of the inspection device drives the main body 62 of the inspection device to rise, causing the inspection head 61 to move towards the conical surface of the vent screw 5 until the inspection head 61 hits the conical surface 53 under the vent screw. At this time, the conical surface presses on the round hole of the inspection head 61. The inside of the inspection head is inflated for 2 seconds, and then the pressure is maintained for 5 seconds. The leakage is detected to be higher or lower than the inspection standard. The specific principle is that the air tightness is qualified if the air tightness meets the following conditions: ≤0.3cc / min, 2.5±0.3bar (inflation time 2s, pressure holding time 5s, test time 7s). Otherwise, it is unqualified. The structure can be referred to the patent with publication number CN209639944U entitled: Detection Device for Conical Surface Jumping of Vent Screw.

[0056] Specifically, the detection head 61 is a tubular structure with a hole at the end for inserting a conical surface. The inside of the detection head 61 is connected to an air source and a pneumatic gauge. After the conical surface mates with the circular hole in the detection head 61, a relatively sealed space is formed inside. The air source fills this space with air, and the pneumatic gauge measures the leakage. The measurement data is then automatically used by a computer system or PLC controller to determine whether the product is qualified. In this embodiment, a PLC controller (Siemens S7-1200 series) is preferably used, with TIA Portal V15 as the programming software. The control program is set to an automatic operation mode, with a processing cycle of 5 seconds per piece. A screen is installed on the frame, and the human-machine interface includes a parameter adjustment interface, allowing real-time modification of parameters such as drilling depth and detection pressure.

[0057] like Figure 3 , Figure 6 The sorting module 3 includes a qualified product flow channel 32, a qualified product box 31, a non-qualified product flow channel 33, a plate 35, and a plate driving assembly. The qualified product flow channel 32 is provided with sorting holes, and the workpiece can enter the non-qualified product flow channel 33 through the through holes. The plate 35 is connected to the plate driving assembly, which is used to drive the plate 35 to move and open and close the sorting holes.

[0058] The plate drive assembly preferably uses a cylinder or any linear module.

[0059] Both the qualified product flow channel 32 and the unqualified product flow channel 33 are inclined and use gravity to achieve product sorting. The unqualified product flow channel 33 is located below the qualified product flow channel 32. The structure is simple and the cost is low. The extension directions of the qualified product flow channel 32 and the unqualified product flow channel 33 are intersecting, so that the flow directions of qualified products and unqualified products are staggered and easy to distinguish. The qualified product material box 31 is located at the end of the qualified product flow channel 32.

[0060] When the conical surface detection module 6 detects that the conical surface of the workpiece is unqualified, the air nozzle 24 blows the workpiece away from the processing and inspection station, the workpiece is transferred to the qualified product flow channel 32 and moves along the qualified product flow channel 32, the plate body drive assembly drives the plate body 35 to move so that the sorting hole is opened, and the workpiece is transferred from the sorting hole to the unqualified product flow channel 33 for discharge.

[0061] When the conical surface detection module 6 detects that the conical surface of the workpiece is qualified, the deep hole drilling assembly 21 and the side hole drilling assembly 22 process the workpiece. After processing, the air blowing nozzle 24 blows the workpiece away from the processing and inspection station, and the workpiece is transferred to the qualified product flow channel 32 and discharged along the qualified product flow channel 32.

[0062] By integrating the conical surface detection module 6 with the processing module 2, the detection results are judged in real time by the control system. Defective products enter the defective product outlet through the air blowing slide, while qualified products enter the next processing step. The dual-station synchronous drilling mechanism realizes the synchronous processing of the two holes of the venting screw. The sorting module 3 realizes the automatic separation of qualified and defective products. These technological innovations have significantly improved the processing efficiency of the equipment, shortened the cycle time to 5 seconds / piece, and ensured the processing quality and detection reliability, reducing the need for manual intervention. It is particularly suitable for the processing needs of large batches and high precision venting screws.

[0063] Processing steps:

[0064] When the equipment is working, the deflating screws to be processed are first automatically arranged and conveyed by a vibratory feeder, with the vibration frequency set to 80Hz. When the workpiece reaches the processing position, the photoelectric sensor (Omron E3Z-T61) detects a signal, and the PLC controls the lifting drive 63 of the detection device to mate the conical surface with the circular hole of the detection head 61 for conical surface detection, with the detection pressure set to 0.3MPa. Workpieces that fail the inspection (conical surface angle deviation exceeds ±0.5°) are blown out by the air nozzle (air pressure 0.4MPa) and discharged through the non-conforming product flow channel 33.

[0065] For qualified workpieces, the hexagonal cylinder caliper simultaneously clamps the workpiece for 0.5 seconds. Then, the electric cylinder lift moves the deep small hole drill bit (3mm diameter) downwards, while the side hole cylinder pushes the side hole drill bit (2.5mm diameter) forward, completing simultaneous machining of two holes. The drilling depths are 8mm and 5mm respectively, with a feed rate of 10mm / s for both. During machining, cutting fluid (5% emulsion concentration) is sprayed at a flow rate of 30ml / min for cooling.

[0066] During drilling, the detection head 61 may or may not detach from the workpiece's conical surface; detachment is preferred. When the conical surface detection module 6 detects that the workpiece's conical surface is qualified, the detection device's lifting drive 63 drives the detection head 61 to move and detach from the workpiece's conical surface, and then the workpiece undergoes drilling. After the detection head 61 moves and detaches from the workpiece's conical surface, the workpiece's conical surface remains within the positioning hole 15, ensuring the stability of the machining process and preventing wear and tear on the detection head 61 caused by workpiece vibration during machining. This ensures the detection head 61's detection accuracy and service life. After the detection head 61 moves and detaches from the workpiece's conical surface, a shield may or may not be provided at the gap between them.

[0067] After processing, the cylinder resets, and the air nozzle blows the workpiece into the qualified product flow channel 32 at a pressure of 0.4 MPa, where it enters the qualified product receiving box. The entire processing cycle is completed within 5 seconds, and the equipment capacity can reach 720 pieces / hour.

[0068] When the vibratory feeder is short of material, the alarm light on the top of the frame flashes red and the machine stops; when there is a processing abnormality, the alarm light turns on yellow; when the equipment is running normally, the green light stays on.

[0069] The equipment maintenance cycle is to replenish cutting fluid every 8 hours of operation and check drill bit wear every 200 hours of operation. When replacing drill bits, a dedicated tool setter is used to ensure that the coaxiality of the two drill bits is within 0.02mm. The equipment noise is controlled below 75 decibels, which meets industrial environmental standards.

[0070] All functional modules are connected via a CAN bus to transmit operational data in real time. Historical data can be stored for 30 days for easy quality traceability. The equipment is powered by AC220V±10%, 50Hz, with a total power of 2.2kW. The grounding resistance is less than 4Ω to ensure operational safety.

[0071] Example 2:

[0072] Based on Example 1, after the detection head 61 moves and disengages from the workpiece conical surface, a shield is placed in the gap between them. For example... Figure 7A sealing door 7 is provided in the positioning hole 15. After the detection head 61 is separated from the workpiece conical surface, the sealing door 7 is located between the detection head 61 and the workpiece and is closed. The sealing door can prevent chips and cutting fluid from entering the detection head 61 and ensure the normal use of the detection device.

[0073] The closed door 7 can be optionally equipped with a drive module or pushed open by the detection head 61.

[0074] In this embodiment, the closed door 7 includes two sets of double-leaf door panels disposed in the positioning hole 15. The door panels are installed by spring hinges. When the detection head 61 moves toward the conical surface of the workpiece, it pushes open the door panels, allowing the detection head 61 to move smoothly up and down. The cross-section of the positioning hole 15 at the location of the closed door 7 can be circular or square, and its diameter should be larger than the outer diameter of the detection head 61. The shape of the door can be circular or square, as long as it can cover the upper side of the detection head 61. After the door panel is pushed by the detection head 61, it is in a vertical state. The positioning hole 15 on one side of the door panel rotation opening direction can be configured as an open type or have a receiving space. An open type means that it is connected to the outside. After the door panel is opened, if there is cutting fluid or chips on the upper side of the door panel, they can be discharged through the open channel on the hole wall of the positioning hole 15 or collected in the receiving space during the flipping process.

[0075] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand and implement the present invention. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
