Description

Technical Field

[0001] This invention belongs to the field of intelligent manufacturing technology, specifically relating to a general processing device and method for linkage components of lock products. Background Technology

[0002] Linkage components are an important part of lock components and are widely used in the upper locks of trigger-type hatches. The boring and milling of linkages is usually done using a machining center. Due to the large batch size, this results in long-term occupation of high-precision machining center resources and a high frequency of rework, leaving significant room for improvement in processing efficiency and quality.

[0003] Connecting rods in linkage components mainly include I-beam and herringbone shapes. Currently, the process route for boring and milling is as follows: after milling on a machining center, a fitter deburrs the rods and then grinds the hole to the final size. Due to the short hole depth, this process route has low processing efficiency; it also cannot machine helical grooves, making it difficult to remove the helical groove burrs generated after boring (upstream process); grinding easily destroys the form and position tolerances guaranteed by the original milling process, and grinding requires a high level of operator skill. When machining different types of connecting rods, different clamping fixtures need to be configured for different types of connecting rods. During machining, the clamping fixtures need to be changed and repositioned, resulting in low processing efficiency and high operational intensity. Summary of the Invention

[0004] The purpose of this invention is to provide a universal processing device and method for linkage assemblies of lock products, so as to solve the problem of low processing efficiency and high operational intensity caused by the need to configure different clamping fixtures for different types of linkages.

[0005] This invention is achieved through the following technical solution: A universal processing device for locking product linkage assemblies, used for processing different types of linkages, one type of linkage having a linkage bracket and linkage lug, and another type of linkage having a linkage hole; all linkages have two connection holes; including: The positioning plate has a first positioning hole and a second positioning hole, which are used for positioning the two connecting holes on different types of connecting rods. A boss is provided on the positioning plate, with a positioning groove for the connecting rod bracket to extend into, used for positioning the connecting rod bracket.

[0007] In some embodiments, a fixing screw is provided on the boss, one end of the fixing screw extends into the positioning groove, and the side of the positioning groove opposite to the fixing screw is provided as a positioning surface for positioning the connecting rod bracket.

[0008] In some embodiments, it also includes: The first reading unit is used to read information of the first identifier; The second sensing unit is used to receive the sensing information from the first sensing unit; The control unit obtains the type of the positioning plate based on the information of the first identifier, controls the CNC lathe tool to move to an initial position that matches the positioning plate, and enables the second sensing unit to move with the tool to a position that can receive the sensing information of the first sensing unit.

[0009] In some embodiments, the first sensing unit is positioned such that when one type of link is positioned and installed on the positioning plate, the link bracket of the link can block the first sensing unit, and when another type of link is positioned and installed on the positioning plate, the link will not block the first sensing unit.

[0010] In some embodiments, when the link is positioned and installed on the positioning plate, the control unit determines the type of the link based on whether the second sensing unit can receive the sensing information from the first sensing unit.

[0011] In some embodiments, the first sensing unit and the second sensing unit are respectively an infrared transmitter and an infrared receiver.

[0012] In some embodiments, a zero-point positioning fixture is further included, wherein the positioning plate is provided with a positioning pin for positioning and clamping on the zero-point positioning fixture.

[0013] In some embodiments, the clamping assembly includes a clamping member, a clamping screw, and a support member, wherein the clamping screw passes through the clamping member and is connected to a positioning plate, and the support member is disposed on the positioning plate and supports the end of the clamping member away from the clamping end.

[0014] On the other hand, the present invention also provides a method for processing linkage assemblies for lock products, which uses the general processing device for lock product assemblies to process the linkage; including the following steps: Read the information of the first identifier, and obtain the type of the current positioning plate based on the information of the first identifier; Based on the type of the current positioning plate, the CNC lathe tool is controlled to move to an initial position that matches the current positioning plate, and at the initial position, it can receive sensing information from the first sensing unit. Output processing start information, detect whether the sensing information of the first sensing unit can be received. When the sensing information can be received, obtain the first processing control program to process the connecting rod.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0030] like Figure 1 and2 The figure shows a herringbone connecting rod 401. This type of connecting rod has two connecting holes with diameters of 10mm and 8mm respectively, and the distance between the connecting holes is 29.5mm. The connecting rod has connecting hole parts 42 corresponding to the two connecting holes, and the connecting rod is provided with a connecting rod bracket 43 and a connecting rod lug 44.

[0031] like Figure 3 and 4 The image shows an I-shaped connecting rod 402. This type of connecting rod also has two connecting holes, each with a diameter of 8mm, and the distance between the connecting holes is 31.5mm. The connecting rod is provided with a connecting rod hole 45.

[0032] The structural comparison of the two types of connecting rods shows that the difference between them lies in the diameter and spacing of one of the holes. The difference in hole diameter is 2mm, and the difference in hole spacing is also 2mm. By utilizing the structural characteristics of the two types of connecting rods, the processing device is designed to be suitable for processing both types of connecting rods.

[0033] One of the objectives of this invention is to provide a universal machining device that can be applied to both herringbone and I-shaped connecting rods, in order to solve the problem that different types of connecting rods require different tooling for machining.

[0034] In some embodiments of the present invention, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a general processing device for linkage assemblies of lock products includes: The positioning plate 20 has a first positioning hole 221 and a second positioning hole 222, which are used for positioning the two connecting holes on different types of connecting rods. A boss 23 is provided on the positioning plate, and a positioning groove 24 is provided on the boss 23 for the connecting rod bracket to extend into. The positioning groove 24 is used for positioning the connecting rod bracket. A positioning hole 26 is provided on the positioning plate 20 to mate with the connecting rod hole. A first identifier 51 for identifying the type of positioning plate and a first sensing unit 52 for identifying the type of connecting rod installed on the positioning plate are provided on the positioning plate 20. The clamping assembly is used to clamp the connecting rod onto the positioning plate.

[0035] The general-purpose processing device in this embodiment utilizes the structural relationship and characteristics of the two types of connecting rods to design a first positioning hole and a second positioning hole on the positioning plate. The first positioning hole and the second positioning hole can be used simultaneously to position the connecting holes on the herringbone and I-shaped connecting rods. Furthermore, utilizing the structural characteristics of each connecting rod, other corresponding positioning structures are designed on the positioning plate to achieve accurate positioning of the two types of connecting rods on the positioning plate, enabling the positioning plate to be used simultaneously for positioning processing of the two types of connecting rods.

[0036] A first identifier 51 is set on the positioning plate, such as a QR code, to identify the type of the positioning plate. A first sensing unit is set on the positioning plate to emit sensing information. Based on the first identifier, the processing equipment can automatically identify the type of the positioning plate and obtain information about the connecting rod to be processed, thereby preparing for processing. Furthermore, based on the sensing information, the type of connecting rod installed on the positioning plate can be automatically identified to realize automatic processing of the connecting rod and ensure safety during the processing of different types of connecting rods.

[0037] In some embodiments, refer to Figure 7 and Figure 8 Both the first positioning hole portion 221 and the second positioning hole portion 222 are stepped holes, including a large hole portion and a small hole portion. The circumferential surface of the large hole portion includes a first semi-circular surface 223 facing outward and a second semi-circular surface 224 facing inward. The first semi-circular surface 223 and the second semi-circular surface 224 are used for positioning and fitting with the connecting hole portion on different types of connecting rods, and enable the small hole portion to simultaneously adapt to the machining of connecting rod holes on different types of connecting rods.

[0038] like Figure 7 and Figure 8 As shown, the first semi-circular surface 223 of the first positioning hole and the second positioning part are respectively configured to mate with the outer sides of the two connecting holes of the I-shaped connecting rod, for positioning and installing the I-shaped connecting rod on the positioning plate; at the same time, using the positioning holes provided on the positioning plate and the connecting rod holes on the connecting rod, a positioning pin 27 is inserted into the connecting rod holes and the positioning holes. At this time, the positioning and installation of the I-shaped connecting rod on the positioning plate is achieved through the insertion and positioning of the first semi-circular surface, the positioning hole and the positioning pin.

[0039] The second semi-circular surfaces 224 of the first positioning hole and the second positioning part are respectively configured to mate with the inner sides of the two connecting holes of the herringbone connecting rod, for positioning and installing the herringbone connecting rod on the positioning plate; at the same time, the positioning groove on the positioning plate is used to position the connecting rod bracket. At this time, the positioning and installation of the herringbone connecting rod on the positioning plate is achieved through the positioning of the second semi-circular surface and the positioning groove.

[0040] In some embodiments, a fixing screw 25 is provided on the boss 23, with one end of the fixing screw 25 extending into the positioning groove 24. The side of the positioning groove 24 opposite to the fixing screw is provided as a positioning surface 241 for positioning the connecting rod bracket. By providing a fixing screw on the boss, the connecting rod bracket is tightly fitted into the positioning groove, thereby achieving better positioning of the connecting rod while fixing it on the positioning plate.

[0041] Reference Figure 5 and Figure 6 The clamping assembly includes a clamping member 30, a clamping screw 31, and a support member 32. The clamping screw 31 passes through the clamping member 30 and is threadedly connected to the positioning plate 20. The support member 32 is disposed on the positioning plate 20 and supports the end of the clamping member away from the clamping end.

[0042] The support member 32 and the positioning plate 20 are connected by threads to facilitate the adjustment of the support height.

[0043] The clamping member 30 is provided with a waist-shaped hole 301, and the clamping screw 31 is fitted into the waist-shaped hole 301. The support member 32 is made of hex socket screw. The waist-shaped hole 301 has a stepped structure, and the clamping screw is fitted into the stepped structure to apply a clamping force to the clamping member. At the same time, the waist-shaped hole allows for easy adjustment of the support member.

[0044] In some embodiments, the general processing device for linkage assemblies of lock products further includes a zero-point positioning fixture. The positioning plate is provided with a positioning pin for positioning and clamping on the zero-point positioning fixture. The positioning plate can achieve rapid positioning and alignment on the part positioning fixture, ensuring positioning accuracy. Furthermore, it can quickly switch between different connection holes when processing them, without the need for repeated alignment, thus improving processing efficiency.

[0045] In some embodiments, refer to Figure 9 The general processing equipment for linkage assemblies of lock products also includes: The first reading unit 53 is used to read information of the first identifier, such as using a barcode scanner to identify QR code information. The second sensing unit 54 is used to receive the sensing information of the first sensing unit. The first sensing unit can be an infrared transmitter, and the second sensing unit can be an infrared receiver. The infrared receiver receives the infrared information emitted by the infrared transmitter. The control unit 50 obtains the type of the positioning plate according to the information of the first identifier, controls the CNC lathe tool to move to an initial position that matches the positioning plate, and enables the second sensing unit to move with the tool to a position that can receive the sensing information of the first sensing unit.

[0046] By obtaining the type of the positioning plate, the corresponding control program is selected from the program library according to the type information of the positioning plate, and the CNC lathe is controlled. The CNC lathe is prepared before machining. At the same time, the second sensing unit can move with the tool to a position where it can receive the sensing information of the first sensing unit, so as to prepare for the subsequent determination of the linkage type.

[0047] In some embodiments, the position of the first sensing unit is designed by further utilizing the structural differences and characteristics of the herringbone link and the I-beam link. Specifically, the position of the first sensing unit is such that when the herringbone link is positioned and installed on the positioning plate, the link bracket of the herringbone link can block the first sensing unit, and when the I-beam link is positioned and installed on the positioning plate, the I-beam link will not block the first sensing unit.

[0048] At this time, when the connecting rod is positioned and installed on the positioning plate, the control unit determines the type of the connecting rod based on whether the second sensing unit can receive the sensing information from the first sensing unit, and then automatically calls the corresponding machining program and parameters for machining.

[0049] On the other hand, in some embodiments of the present invention, a method for processing a linkage assembly for lock products is provided, which processes the linkage based on the aforementioned general processing apparatus for lock product assemblies, and includes the following steps: Read the information of the first identifier, and obtain the type of the current positioning plate based on the information of the first identifier; Based on the type of the current positioning plate, the CNC lathe tool is controlled to move to an initial position that matches the current positioning plate, and at the initial position, it can receive sensing information from the first sensing unit. Output processing start information, detect whether the sensing information of the first sensing unit can be received. When the sensing information can be received, obtain the first processing control program to process the connecting rod. When the sensing information cannot be received, obtain the second processing control program to process the connecting rod.

[0050] When processing using the general processing device and processing method in this embodiment, the positioning plate is positioned and installed on the zero-point positioning fixture; the information of the first identifier is read by the barcode scanner to identify the type of the current positioning plate; the control unit controls the CNC lathe tool to move to the initial position according to the information of the first identifier; at this time, the second sensing unit can receive the sensing information of the first sensing unit. The herringbone connecting rod is positioned and installed on the positioning plate, and the connecting rod is clamped and fixed using a clamping assembly to complete the positioning and clamping of the connecting rod. At this time, the connecting rod bracket blocks the first sensing unit, preventing the second sensing unit from receiving the sensing information from the first sensing unit. The control unit outputs processing start information. Since the second sensing unit cannot receive the sensing information, the control unit determines that the part to be processed is the herringbone connecting rod, and the control program calls the second processing control program for processing herringbone connecting rods from the program library to perform the processing operation of the connecting rod.

[0051] The I-shaped connecting rod is positioned and installed on the positioning plate, and the connecting rod is clamped and fixed using a clamping assembly to complete the positioning and clamping of the connecting rod. At this time, the connecting rod will not block the first sensing unit, allowing the second sensing unit to receive the sensing information from the first sensing unit. The control unit outputs processing start information, and the second sensing unit can receive the sensing information. The control unit determines that the part to be processed is the I-shaped connecting rod, and the control program calls the first processing control program for I-shaped connecting rod processing from the program library to perform the processing operation of the connecting rod.

[0052] During the machining of the connecting rod, one hole is machined first, and then the positioning plate is rotated so that the second hole is positioned at the machining station. The second hole is then machined. This avoids the cumulative error caused by the secondary clamping of the connecting rod and improves the machining accuracy.

[0053] The positioning pin is set at the midpoint of the line connecting the center of the first positioning hole and the center of the second positioning hole. In the positioning installation of the positioning plate, the first positioning hole and the second positioning hole are set along the X-axis direction of the tool. In this way, when changing the machining program during the machining of different types of connecting rods, it is only necessary to control the tool to move 1mm along the X-axis direction, without repeating the tool setting, which ensures the machining accuracy and further improves the machining efficiency.

[0054] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in during use. They are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0055] Furthermore, the use of terms such as "horizontal" and "vertical" in the description of this invention does not imply that the components are required to be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0056] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
