Description

Technical Field

[0001] This application relates to the field of sealing strip processing technology, and in particular to a novel equipment for automatic sealing strip buckle hole cutting. Background Technology

[0002] Automotive weatherstripping plays a crucial role in automobile manufacturing, primarily used to fill gaps between body parts, and providing functions such as shock absorption, waterproofing, dustproofing, sound insulation, and decoration. To ensure a tight fit between the weatherstripping and the automotive sheet metal, holes are typically drilled in the weatherstripping and clips or fasteners are installed.

[0003] Most existing sealing strip drilling equipment uses pneumatic drill sets for drilling operations. For example, Chinese patent application "A Multi-Position Sealing Strip Drilling Equipment" (application number: CN202222949114.3) discloses a device including a frame. Two or more X-axis sliding cylinders are fixedly mounted on the top of the frame. A lower crossbeam is fixedly connected to the slides of the two or more X-axis sliding cylinders. A part mold is fixedly connected to the lower crossbeam, and a part placement groove is formed on the part mold. A mounting frame is fixedly mounted on the top of the frame, located on one side of the part mold. Two or more Y-axis sliding cylinders are fixedly mounted on the mounting frame. An upper crossbeam is fixedly connected to the slides of the two or more Y-axis sliding cylinders. A left-side pneumatic drill set and a right-side pneumatic drill set are fixedly mounted at the left and right ends of the upper crossbeam, respectively. A PLC control cabinet and an air tank are fixedly mounted inside the frame, and a controller is fixedly mounted on the front of the frame. This invention can greatly improve the drilling efficiency of sealing strips, reduce the labor intensity of workers, save labor costs, and reduce safety hazards.

[0004] However, the aforementioned equipment has some significant shortcomings. The fixed position and structure of the pneumatic drill assembly in existing equipment limit its processing capabilities to specific models or specifications of sealing strips, lacking versatility. This limitation necessitates manufacturers equipping different drilling devices for different sealing strip models, increasing procurement and maintenance costs. Furthermore, the inflexible nature of the equipment restricts production line flexibility, making it difficult to adapt to the demands of multi-variety, small-batch production. Therefore, a versatile and flexibly adjustable sealing strip drilling device is urgently needed to reduce production costs, improve processing efficiency, and ensure product quality. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a new type of equipment, namely, an automatic sealing strip punching and cutting machine, which can flexibly adjust the position of the drilling group to reduce production costs and improve processing efficiency.

[0006] The technical solution adopted in this application is: a new type of equipment for automatic punching and cutting of sealing strips, including a frame, the frame including a table and a back frame erected vertically on the table, a fixed tooling module detachably installed on the table, the sealing strip to be processed is installed on the fixed tooling module, the fixed tooling module is provided with a cutting knife group connected to a power device, the back frame is provided with a transverse slide rail, multiple mounting brackets are provided on the slide rail, the mounting brackets can move along the slide rail, and a drilling component is detachably installed on the mounting bracket, the drilling component is located above the sealing strip to be processed.

[0007] Compared with existing technologies, the advantages of this application lie in the fact that the transverse slide rail and movable mounting bracket on the back frame form a two-dimensional adjustable system. By setting the sliding mounting bracket, the transverse position of the drilling component can be flexibly adjusted, overcoming the limitations of traditional fixed pneumatic drill sets. Specifically, multiple mounting brackets are movably mounted on the slide rail, and drilling components are detachably mounted on these brackets. Therefore, this application can set mounting brackets at the corresponding positions according to the required drilling locations of the sealing strip, and then install the drilling components on the mounting brackets, resulting in greater flexibility and better versatility. Furthermore, the fixed tooling module of this application adopts a modular quick-change design, achieving rapid replacement through a standardized structure, supporting the clamping of sealing strips with different cross-sectional shapes. Combined with the flexible adjustability of the drilling components, this application has high adaptability, thereby reducing the production and processing costs of the sealing strip. It eliminates the need for additional customized drilling equipment and simultaneously completes the drilling and cutting processes, effectively improving the processing efficiency of the sealing strip.

[0008] In some embodiments of this application, the mounting bracket is equipped with a locking element connected to the slide rail. When the locking element is locked, the mounting bracket and the slide rail are relatively fixed; when the locking element is unlocked, the mounting bracket can move along the slide rail. The operator can adjust the position of the mounting bracket according to the actual drilling position required for the sealing strip to be processed, and install drilling parts on the corresponding mounting bracket to meet the drilling requirements of different sealing strips.

[0009] In some embodiments of this application, the mounting bracket is an L-shaped support structure, the mounting bracket includes a back plate and a support plate, the back plate is connected to a slide rail, the support plate has a mounting hole that penetrates the top and bottom surfaces of the support plate, and the side of the support plate has an insertion hole equipped with a pin.

[0010] In some embodiments of this application, the drilling component includes a motor and a drill bit. The motor is mounted at a mounting hole, and a pin passes through the hole to act on the motor. The drill bit extends from a support plate. The motor is locked by the pin, enabling quick installation or removal of the drilling component. Specifically, the pin can employ a spring plunger structure to ensure that the motor does not shift under vibration.

[0011] In some embodiments of this application, a storage plate is provided on the top of the back frame, and the storage plate is evenly distributed with storage holes for placing drilling parts. Idle or spare drilling parts can be placed on the storage plate. In actual use, drilling parts need to be connected to electrical equipment and are not suitable for repeated disconnection and connection. Therefore, the drilling parts are integrated on the frame, while the fixed tooling module can be disassembled and replaced.

[0012] In some embodiments of this application, a positioning reference element is provided at one end of the storage plate. The positioning reference element includes an upper card holder and a lower socket. There is a predetermined distance between the upper card holder and the lower socket. The motor of the drilling component is mounted on the upper card holder, and the drill bit end of the drilling component is inserted into the lower socket.

[0013] In some embodiments of this application, a slot is provided on the front side of the lower socket, the slot penetrating the top and bottom surfaces of the lower socket, and the transverse cross-section of the slot is semi-circular. That is, when the drill bit of the drilling component is inserted into the slot, the insertion depth of the drill bit can be visually observed from the front side. Furthermore, a go / no-go gauge is provided on one side of the positioning reference component, which allows for more precise determination of whether the drill bit position of the drilling component is standard.

[0014] In order to achieve synchronous and precise machining of multiple holes on the sealing strip in this application, it is necessary to ensure that the drill bits of multiple drilled parts are located on the same horizontal plane. Therefore, a positioning reference component is further set to inspect the drilled parts.

[0015] In some embodiments of this application, the back frame is provided with a vertical drive device, and the slide rail is connected to the back frame through the vertical drive device. The vertical drive device drives the slide rail to move up and down.

[0016] In some embodiments of this application, the up-and-down driving device includes a rotary drive component, a rotating shaft, and two sets of left and right pulleys. Each pulley set includes an upper drive pulley, a lower drive pulley, and a transmission belt connecting the upper and lower drive pulleys. The rotary drive component is installed between the two upper drive pulleys, and the rotating shaft connects the two upper drive pulleys to the rotary drive component. The slide rail is mounted on the transmission belt at the same height. The rotary drive component operates by driving the transmission belt through the two upper drive pulleys. The dual pulley sets are driven by the same rotating shaft, eliminating the risk of asynchronous lifting on both sides. The two sets of left and right pulleys can bear the total weight of the horizontal plate and slide rail, meeting the integration requirements of multiple drilled parts.

[0017] In some embodiments of this application, the back frame is equipped with two balancing cylinders, one on the left and one on the right. The balancing cylinders adjust the horizontality of the crossbar in real time to counteract tilting caused by belt wear or uneven load.

[0018] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

Detailed Implementation

[0025] The present application will now be described in detail with reference to the accompanying drawings.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] A new type of equipment, the automatic sealing strip buckle hole punching and precision cutting machine, as shown in Example 1. Figure 1As shown: The machine includes a frame 1, which includes a table 2 and a back frame 3 vertically mounted on the table 2. A fixing tooling module 7 is detachably installed on the table 2. The sealing strip 10 to be processed is installed on the fixing tooling module 7. A cutting blade assembly 8 connected to a power unit is provided inside the fixing tooling module 7. The fixing tooling module 7 of this application adopts a modular quick-change design, achieving rapid replacement through a standardized structure. It supports the clamping of sealing strips 10 with different cross-sectional shapes. Combined with the flexible adjustability of the drilling component 6, this application has high adaptability, thereby reducing the production and processing cost of the sealing strip 10. It eliminates the need for additional customized drilling equipment and simultaneously completes the drilling and cutting processes, effectively improving the processing efficiency of the sealing strip 10.

[0028] The back frame 3 is equipped with a transverse slide rail 4, on which multiple mounting brackets 5 are mounted. The mounting brackets 5 are movable along the slide rail 4, and a drilling component 6 is detachably mounted on each mounting bracket 5, positioned above the sealing strip 10 to be processed. The transverse slide rail 4 and the movable mounting brackets 5 form a two-dimensional adjustable system. By using the sliding mounting brackets 5, the transverse position of the drilling component 6 can be flexibly adjusted, overcoming the limitations of traditional fixed pneumatic drill sets. This application allows for the installation of mounting brackets 5 at the corresponding positions where drilling is required on the sealing strip 10, and then the mounting brackets 5 are used to install the drilling component 6, resulting in greater flexibility and better versatility.

[0029] The back frame 3 is equipped with two balancing cylinders 52, one on the left and one on the right. The balancing cylinders 52 adjust the level of the cross plate 22 in real time to counteract tilting caused by belt wear or uneven load.

[0030] Example 2, as Figures 1 to 3 As shown, the mounting bracket 5 is equipped with a locking element that connects to the slide rail 4. When the locking element is locked, the mounting bracket 5 and the slide rail 4 are relatively fixed; when the locking element is unlocked, the mounting bracket 5 can move along the slide rail 4. The operator can adjust the position of the mounting bracket 5 according to the actual drilling position required for the sealing strip 10 to be processed, and install the drilling element 6 on the corresponding mounting bracket 5 to meet the drilling requirements of different sealing strips 10.

[0031] The mounting bracket 5 has an L-shaped support structure. The mounting bracket 5 includes a back plate 45 and a support plate 46. The back plate 45 is connected to the slide rail 4. The support plate 46 has a mounting hole that passes through the top and bottom surfaces of the support plate 46. The side of the support plate 46 has an insertion hole equipped with a pin 49.

[0032] The drilling component 6 includes a motor 50 and a drill bit 51. The motor 50 is mounted at the mounting hole, and a pin 49 passes through the hole and acts on the motor 50. The drill bit 51 extends out from the support plate 46. The motor 50 is locked by the pin 49, enabling quick installation or removal of the drilling component 6. Specifically, the pin 49 can adopt a spring plunger structure to ensure that the motor 50 does not shift under vibration.

[0033] like Figures 1 to 4 As shown, the top of the back frame 3 is provided with a storage plate 38, and the storage plate 38 is evenly distributed with storage holes 39 for placing the drilling parts 6. Idle or spare drilling parts 6 can be placed on the storage plate 38. In actual use, the drilling parts 6 need to be connected to electrical equipment and are not suitable for repeated disconnection and connection. Therefore, the drilling parts 6 are integrated into the frame 1, while the fixed tooling module 7 can be disassembled and replaced.

[0034] One end of the storage plate 38 is provided with a positioning reference component 40, which includes an upper card holder 41 and a lower socket 42. There is a predetermined distance between the upper card holder 41 and the lower socket 42. The motor 50 frame 1 of the drilling component 6 is mounted on the upper card holder 41, and the end of the drill bit 51 of the drilling component 6 is inserted into the lower socket 42.

[0035] The lower socket 42 has a slot 43 on its front side, which penetrates the top and bottom surfaces of the lower socket 42. The transverse cross-section of the slot 43 is semi-circular. This means that when the drill bit 51 of the drilling component 6 is inserted into the slot 43, the insertion depth of the drill bit 51 can be visually observed from the front side. Furthermore, a go / no-go gauge is provided on one side of the positioning reference component 40, which allows for more precise determination of whether the position of the drill bit 51 of the drilling component 6 is standard. In this application, to achieve simultaneous and precise machining of multiple holes on the sealing strip 10, it is necessary to ensure that the positions of the drill bits 51 of multiple drilling components 6 are on the same horizontal plane. Therefore, a positioning reference component 40 is further provided to inspect the drilling components 6.

[0036] The rest of the contents of Example 2 are the same as those of Example 1.

[0037] Example 3, as Figures 1 to 3 As shown, the back frame 3 is equipped with a vertical drive device, and the slide rail 4 is connected to the back frame 3 through the vertical drive device. The vertical drive device drives the slide rail 4 to move up and down.

[0038] The up-and-down driving device includes a rotary drive component 29, a rotating shaft 30, and two sets of left and right pulleys. Each pulley set includes an upper drive pulley 32, a lower drive pulley 33, and a transmission belt 34 connecting the upper and lower drive pulleys 33. The rotary drive component 29 is installed between the two upper drive pulleys 32, and the rotating shaft 30 connects the two upper drive pulleys 32 to the rotary drive component 29. The slide rail 4 is mounted on the transmission belt 34 at the same height. The rotary drive component 29 operates by driving the transmission belt 34 through the two upper drive pulleys 32. The double pulley sets are driven by the same rotating shaft 30, eliminating the risk of asynchronous lifting on both sides. The two sets of left and right pulleys can bear the total weight of the horizontal plate 22 and the slide rail 4, meeting the integration requirements of multiple drilled parts 6.

[0039] The other contents of Example 3 are the same as those of Example 1 or Example 2.
