Description

Technical Field

[0001] This application relates to the field of accessory head connection technology for floor-type milling and boring machines, and in particular to an accessory head pin socket device for floor-type milling and boring machines. Background Technology

[0002] Floor-type milling and boring machines are essential machining equipment in modern manufacturing, widely used for the precision machining of large parts. These machines are typically equipped with various attachment heads, such as milling heads and boring heads, to meet the machining needs of different workpieces. With the increasing level of industrial automation, the performance and reliability of these machine tools directly impact production efficiency and product quality.

[0003] Currently, the accessory head and the machine tool are generally electrically connected via a pin socket to allow the accessory head to be mounted on the machine tool. For example... Figure 1 As shown, the socket body 1′ on the machine tool includes a first plug-in area 11′ and a second plug-in area 12′. The first plug-in area 11′ is electrically connected to the machine tool through a connecting component 111′, and the second plug-in area 12′ is electrically connected to the machine tool through a connecting structure 122′. The diameter of the first socket 112′ of the first plug-in area 11′ is smaller than the diameter of the second socket 121′ of the second plug-in area 12′. The pins of the accessory head are plugged into the first plug-in area 11′ to realize the electrical connection between the accessory head and the machine tool. The second plug-in area 12′ is used to electrically connect to a spare motor to realize the driving requirements of a specific accessory head.

[0004] However, because the diameter of the first socket 112' in the first insertion area 11' is small, the diameter of the pin on the accessory head that mates with it is correspondingly small. When the pin is inserted into the socket body 1', it is prone to bending and damage. Simultaneously, because the first socket 112' in the first insertion area 11' is redundant, and the second socket 121' in the second insertion area 12' is exposed when no specific accessory head is used, coolant and metal shavings from the machining process can easily splash into the first socket 112' and second socket 121' of the socket body 1' after the accessory head is inserted into the machine tool. These problems result in low reliability of the pin insertion into the socket body 1', easily causing electrical short circuits. Spare pins need to be custom-made, resulting in long procurement cycles, high purchase prices, and downtime, affecting production efficiency and product delivery cycles.

[0005] Among the aforementioned related technologies, there is a defect of insufficient reliability in the pin socket connection when the accessory head is connected to the machine tool. Utility Model Content

[0032] The following is in conjunction with the appendix Figure 1 and attached Figure 2 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0034] like Figure 2 As shown in the figure, this application discloses an accessory head pin socket device (hereinafter referred to as "device") for a floor-type milling and boring machine. The device includes a socket body 1, a sealing member 2, and a pin assembly (not shown in the figure).

[0035] like Figure 2As shown, the socket body 1 is arranged on the floor-type milling and boring machine, and the socket body 1 includes a first plug-in area 11 and a second plug-in area 12. The first plug-in area 11 includes a plurality of first insertion holes, and the second plug-in area 12 includes a plurality of second insertion holes 121. The diameter of the first insertion hole is smaller than the diameter of the second insertion hole 121, and the second plug-in area 12 is electrically connected to the floor-type milling and boring machine through a connecting assembly 111. The blocking piece 2 is used to block the plurality of first insertion holes of the first plug-in area 11. The pin assembly is arranged on the accessory head, and the pin assembly is used to cooperate with the second insertion hole 121 to realize plug-in connection, so that the accessory head is electrically connected to the floor-type milling and boring machine. In this embodiment, the floor-type milling and boring machine adopts a PAMA floor-type milling and boring machine, and the accessory head adopts a TS accessory head.

[0036] Since no special accessory head and standby motor are needed during use, the original connecting structure of the second plug-in area 12 is removed, the original connecting assembly 111 of the first plug-in area 11 is connected to the second plug-in area 12, and the pin assembly corresponding to the second insertion hole 121 is connected to the second insertion hole 121 to realize plug-in connection, so that the accessory head is electrically connected to the floor-type milling and boring machine. The connecting assembly 111 can include wires and necessary electrical elements to realize electrical connection. Compared with the related art, the accessory head is plugged into the first plug-in area 11 by using five pins of the seventeen-pin pin assembly. In this embodiment, the pin assembly is plugged into the second plug-in area 12. Since the diameter of the second insertion hole 121 is larger than that of the first insertion hole, it helps to ensure stable electrical connection between the accessory head and the machine tool, and reduces the problem that the diameter of the pin of the pin assembly is too small due to the need to cooperate with the first insertion hole with a smaller diameter, so that the pin assembly can have sufficient strength and reduce the risk of bending. By plugging into the second insertion hole 121, the problem of coolant and iron filings entering the second insertion hole 121 can be reduced. At the same time, since the first plug-in area 11 no longer needs to be connected, the first plug-in area 11 is blocked by the blocking piece 2, which can reduce the risk of coolant and iron filings entering the first insertion hole during processing, reduce the occurrence of electrical short circuit failure, thereby improving the reliability of the electrical connection of the accessory head and the floor-type milling and boring machine, reducing the failure frequency and downtime caused by the connection problem of the pin assembly and the socket body 1, and thereby improving production efficiency and shortening the delivery cycle. At the same time, since the diameter of the second insertion hole 121 is larger than that of the first insertion hole, the diameter of the pin of the corresponding pin assembly can be increased, the maintenance space can be increased, and the difficulty of maintenance welding can be reduced.

[0037] As Figure 2As shown, optionally, the first and second plug-in hole parts are included in the plurality of second plug-in holes 121, the accessory head includes a first accessory head and a second accessory head, and the plug pin assembly structures of the first and second accessory heads are different. Specifically, the plug pin assembly of the first accessory head is provided with a first plug pin part for cooperating with the first plug-in hole part for plug-in, and the first plug-in hole part is used to identify whether the first accessory head is plugged in. The plug pin assembly of the second accessory head is provided with a second plug pin part for cooperating with the second plug-in hole part for plug-in, and the second plug-in hole part is used to identify whether the second accessory head is plugged in. The first and second plug-in hole parts enable the floor-type milling and boring machine tool to accurately identify different accessory heads, ensuring that the machine tool can accurately and reliably determine which accessory head is currently installed, thereby reducing operation errors caused by incorrect identification, enabling the machine tool to correctly execute corresponding operation instructions when detecting that the corresponding plug pin is inserted, and improving the reliability and safety of the machine tool operation.

[0038] Optionally, the third plug-in hole part is included in the plurality of second plug-in holes 121, and the plug pin assembly includes a third plug pin part for cooperating with the third plug-in hole part for plug-in. The third plug-in hole part is used to identify whether the floor-type milling and boring machine tool clamps the accessory head. If the third plug pin part is inserted into the third plug-in hole part and is electrified, it indicates that the floor-type milling and boring machine tool has clamped the accessory head. If the third plug pin part is not inserted into the third plug-in hole or is not electrified, it indicates that the floor-type milling and boring machine tool has not clamped the accessory head. The third plug-in hole part enables the floor-type milling and boring machine tool to accurately identify whether the accessory head is clamped, effectively preventing equipment failure caused by incorrect operation and improving the safety and reliability of the equipment. At the same time, it reduces the frequent inspection and maintenance work caused by the machine tool's inability to correctly determine the connection state of the accessory head, further improving production efficiency.

[0039] As shown, Figure 2 Optionally, the fourth plug-in hole part is included in the plurality of second plug-in holes 121, and the plug pin assembly includes a fourth plug pin part for cooperating with the fourth plug-in hole part for plug-in. The fourth plug-in hole part is used to identify whether the floor-type milling and boring machine tool releases the accessory head, and the identification and determination process is similar to that of the clamping state, which will not be described here.

[0040] As shown, Figure 2 Optionally, the fifth and sixth plug-in hole parts are included in the plurality of second plug-in holes 121, and the plug pin assembly includes a fifth plug pin part and a sixth plug pin part. The fifth plug pin part is used to cooperate with the fifth plug-in hole part for plug-in, and the sixth plug pin part is used to cooperate with the sixth plug-in hole part for plug-in. The voltage of the fifth plug-in hole part is 0V, and the voltage of the sixth plug-in hole part is greater than 0V, so that the circuit in the accessory head can form a loop, realize the loop formation and reliable connection of the internal circuit of the accessory head, ensure that the accessory head can work normally, and improve the stability and safety of the machine tool operation.

[0041] Optionally, the voltage of the sixth socket part is 24V. By setting the voltage of the sixth socket part to 24V, on the one hand, the internal circuit of the accessory head can reliably form a loop, thereby realizing the recognition of the accessory head by the machine tool and improving the stability and reliability of the operation of the machine tool; on the other hand, the safe voltage of 24V also ensures the personal safety of the operator and reduces the risk of electrical accidents caused by excessively high voltage. The first socket part, the second socket part, the third socket part, the fourth socket part, the fifth socket part and the sixth socket part are all single socket parts in the second sockets 121. The remaining socket parts in the plurality of second sockets 121 can be used as backup sockets to realize plugging when a socket part fails or a new structure electrical connection is needed.

[0042] As shown in Figure 2 Optionally, the device further comprises a fastener 3, and the socket body 1 and the floor-type milling and boring machine tool are each provided with a fastening hole. The fastener 3 cooperates with the fastening hole to connect the socket body 1 to the floor-type milling and boring machine tool. The cooperation of the fastener 3 and the fastening hole enables the socket body 1 to be firmly installed on the floor-type milling and boring machine tool, reducing the loosening of the socket body 1 caused by vibration or impact, thereby improving the stability and reliability of the connection. At the same time, this detachable connection method simplifies the installation process and facilitates maintenance and replacement. The fastener 3 can be a bolt or a screw, and the fastening hole is a threaded hole.

[0043] As shown in Figure 2 Optionally, the blocking piece 2 is made of insulating bakelite. Using insulating bakelite as the blocking piece 2, on the one hand, the physical blocking effect of the insulating bakelite effectively prevents the splashing of cooling liquid and iron filings into the first socket; on the other hand, it can guarantee the insulation effect of the first plugging area 11, reduce the problem of electrical short circuit, thereby improving the reliability and stability of the electrical connection between the accessory head and the floor-type milling and boring machine tool, and reducing the downtime caused by connection failure of the pin assembly and the socket body 1.

[0044] It can be understood that since the original connection assembly 111 is connected to the second plugging area 12, the functions realized by the original socket structure in the related art can be transferred from the first plugging area 11 to the second plugging area 12, thereby maintaining the original functions such as accessory head recognition, recognition of clamping or loosening state, and formation of accessory head loop, and the implementation principle remains unchanged. The device also includes necessary structures for electrical connection, support, sealing and control, etc. to enable the device to operate normally; the shape, size, material and number of each part of the device can be determined as needed to achieve the corresponding functions.

[0045] The implementation principle of the embodiment of the accessory head pin socket device of the floor-type milling and boring machine is that the original connecting assembly 111 of the first plug-in area is connected to the second plug-in area 12, and the pin assembly is matched and plugged with the second insertion hole 121, so as to realize the electrical connection between the accessory head and the floor-type milling and boring machine. Since the diameter of the second insertion hole 121 is greater than that of the first insertion hole, the stable electrical connection between the accessory head and the machine tool is ensured, and the problem that the diameter of the pin of the pin assembly is too small due to the need to cooperate with the first insertion hole with a smaller diameter is reduced, so that the pin assembly has sufficient strength and the risk of bending of the pin assembly is reduced. At the same time, since the first plug-in area 11 is no longer needed for connection, the first plug-in area 11 is blocked by the blocking piece 2, which can reduce the risk of cooling liquid and iron filings entering the first insertion hole during machining, reduce the occurrence of electrical short circuit failure, thereby improve the reliability of the electrical connection between the accessory head and the floor-type milling and boring machine, reduce the failure frequency and downtime caused by the connection problem of the pin assembly and the socket body 1, and further improve the production efficiency and shorten the delivery cycle.

[0046] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
