[0002] Before installation, the T-shaped guide rails of an elevator need to undergo end face machining to ensure that the straightness and perpendicularity of the T-shaped guide rails meet the requirements.

[0003] However, existing large-back milling machines for elevator T-shaped guide rails have the following drawbacks in actual production: 1. The elevator T-shaped guide rails are input and output on the same side of the machine. The finished T-shaped guide rails need to be unloaded at the same position, while the next T-shaped guide rail to be processed needs to be loaded at the same position, making continuous processing impossible. After a single processing cycle, the machine tool needs to pause processing and wait for unloading and loading to be completed, increasing loading and unloading time and reducing the overall operating efficiency of the machine tool; 2. The existing T-shaped guide rail fixtures have poor positioning accuracy and cannot adapt to T-shaped guide rails of various specifications and sizes. This technical problem urgently needs to be solved by those skilled in the art. Utility Model Content

[0036] 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.

[0037] like Figure 1-2 As shown, this utility model provides a special machine for back milling of elevator T-shaped guide rails, including a bed 1;

[0038] A slide table 2 is provided on the bed 1. The slide table 2 is a linear slide table. A first milling power head 3 and a second milling power head 4 are installed on the slide table 2. The first milling power head 3 and the second milling power head 4 are arranged at intervals on the same side of the slide table 2.

[0039] The material channel 5 is arranged on the bed 1. The material channel 5 passes through the bed 1 and is arranged perpendicular to the slide table 2. A clamp 6 is provided on the material channel 5. The clamp 6 is used for the lateral and longitudinal positioning of the T-shaped guide rail.

[0040] An auxiliary conveying mechanism 7 is installed on the slide table 2 and moves synchronously with the first milling power head 3 and the second milling power head 4. The auxiliary conveying mechanism 7 is arranged at the end of the material channel 5 and is collinear with the material channel 5.

[0041] The working principle and beneficial effects of the above embodiments are as follows:

[0042] The T-shaped guide rail of this utility model is transported to the processing position through the material channel 5. The material channel 5 passes through the bed 1 and is arranged perpendicular to the slide table 2. The clamp 6 is installed on the material channel 5 to perform lateral and longitudinal positioning of the T-shaped guide rail, so that it remains stable during the processing.

[0043] The first milling power head 3 and the second milling power head 4 are mounted on the same side of the slide table 2 and are arranged at intervals. The movement of the slide table 2 enables the two milling power heads to move along a straight path, thereby processing the T-shaped guide rail. The first milling power head 3 first mills the upper surface of the flange of the T-shaped guide rail, and then the second milling power head 4 mills the end faces of the flange and web of the T-shaped guide rail.

[0044] The auxiliary conveying mechanism 7 is installed on the slide table 2 and moves synchronously with the first milling power head 3 and the second milling power head 4. When the slide table 2 drives the milling power head to move, the auxiliary conveying mechanism 7 also moves accordingly. When the first milling power head 3 and the second milling power head 4 finish processing and return to the waiting position, at this time, the auxiliary conveying mechanism 7 is collinear with the material channel 5 and is arranged at the end of the material channel 5.

[0045] The auxiliary conveying mechanism 7 conveys the processed T-shaped guide rail from the processing area, while making room for the next T-shaped guide rail to be processed. It coordinates with the processing process to ensure the continuity of T-shaped guide rail processing.

[0046] The auxiliary conveying mechanism 7 of this utility model moves synchronously with the slide table 2 and is arranged at the end of the material channel 5 and is collinear with the material channel, so that the conveying and processing of the T-shaped guide rail can be seamlessly connected, realizing continuous processing of the T-shaped guide rail and improving production efficiency.

[0047] In one embodiment,

[0048] like Figure 3 As shown, the first milling power head 3 includes a column 31, a first milling head 32 installed on one side of the column 31, and a top milling cutter 33 installed at the lower end of the first milling head 32. A first motor 34 is provided at the upper end of the first milling head 32.

[0049] The first motor 34 is installed on the upper end of the first milling head 32 and is the power source of the first milling head 32. The first milling head 32 converts the power of the first motor 34 into the rotational motion of the top milling cutter 33, thereby driving the top milling cutter 33 to rotate at high speed. The top milling cutter 33 contacts the T-shaped guide rail and mills the upper surface of the T-shaped guide rail wing plate according to the preset machining path and depth.

[0050] In one embodiment,

[0051] The aforementioned second milling power head 4 includes a second milling head 41, a second motor 42 mounted on one side of the second milling head 41, and a side milling cutter 43 mounted on the output end of the second milling head 41;

[0052] The side milling cutter 43 is installed at the output end of the second milling head 41. When the second motor 42 starts, the side milling cutter 43 starts to rotate through the transmission of the second milling head 41. Through the movement of the slide table 2, the second milling head 41 performs milling on the end face of the T-shaped guide rail.

[0053] In one embodiment,

[0054] like Figure 4As shown, the clamp 6 includes an upper clamping cylinder 61 arranged at the upper end of the material channel 5, a side clamping cylinder 62 arranged on one side of the material channel 5, and a side limiting block 63 arranged on the other side of the material channel 5 and corresponding to the side clamping cylinder 62.

[0055] The side clamping cylinder 62 is arranged on one side of the material channel 5, while the side limiting block 63 is arranged on the other side of the material channel 5, corresponding to the side clamping cylinder 62, and is used to perform lateral positioning and clamping of the T-shaped guide rail. The upper clamping cylinder 61 is arranged at the upper end of the material channel 5 and is used to perform longitudinal positioning and clamping of the T-shaped guide rail.

[0056] When the T-shaped guide rail enters the material channel 5, the upper clamping cylinder 61 and the side clamping cylinder 62 are activated. The upper clamping cylinder 61 extends downward to press the top of the T-shaped guide rail tightly; the side clamping cylinder 62 clamps the side of the T-shaped guide rail tightly onto the side limit block 63 to prevent it from shifting horizontally and vertically during processing.

[0057] The fixture 6 adopts a clamping cylinder design to quickly clamp and release the T-shaped guide rail, achieving high positioning accuracy and significantly improving the subsequent machining accuracy and stability.

[0058] In one embodiment,

[0059] like Figure 5 As shown, the auxiliary conveying mechanism 7 includes a drive assembly 71 mounted on the slide table 2 and a support assembly 72 arranged on both sides of the drive assembly 71. The drive assembly 71 and the support assembly 72 are arranged along the moving direction of the T-shaped guide rail.

[0060] The support assembly 72 is arranged on both sides of the drive assembly 71 to directly contact and support the T-shaped guide rail. The drive assembly 71 is mounted on the slide table 2 and is the power source of the auxiliary conveying mechanism 7. The drive assembly 71 and the support assembly 72 are arranged along the moving direction of the T-shaped guide rail so that the T-shaped guide rail can move smoothly during the conveying process and reduce friction and vibration caused by inconsistent directions.

[0061] After the T-shaped guide rail is processed, the clamp 6 is released, and the T-shaped guide rail is conveyed from the processing position to the end of the material channel 5. The auxiliary conveying mechanism 7 is started to realize the automated conveying of the T-shaped guide rail and improve production efficiency.

[0062] In one embodiment,

[0063] like Figure 6-7 As shown, the drive assembly 71 includes a support frame 711 for passing through the T-shaped guide rail, a cylinder 712 mounted on the support frame 711, a support plate 713 mounted on the telescopic end of the cylinder 712 and slidably mounted in the support frame 711, and an electric roller 714 rotatably mounted on the lower end of the support plate 713, the electric roller 714 contacting the upper surface of the T-shaped guide rail.

[0064] The cylinder 712 is mounted on the support frame 711, and its telescopic end is connected to the support plate 713. The function of the cylinder 712 is to adjust the support plate 713 to a suitable height through telescopic movement, so that the electric roller 714 can accurately contact the upper surface of the T-shaped guide rail. The electric roller 714 rotates and drives the T-shaped guide rail to move, so that the T-shaped guide rail can move smoothly under the drive of the electric roller 714 to complete the conveying task.

[0065] The cylinder 712 can flexibly adjust the position of the support plate 713 according to the height and size of the T-shaped guide rail.

[0066] In one embodiment,

[0067] The aforementioned support assembly 72 includes a U-shaped bracket 721 for passing through the T-shaped guide rail, and tapered rollers 722 rotatably mounted on both sides of the U-shaped bracket 721, wherein the tapered rollers 722 are used to support the T-shaped guide rail.

[0068] Conical rollers 722 are installed on both sides of the U-shaped bracket 721 to directly support the T-shaped guide rail. The design of the conical rollers 722 allows them to adapt to the shape of the lower surface of the T-shaped guide rail flange, reducing friction through rolling, thereby achieving smooth transmission of the T-shaped guide rail.

[0069] In one embodiment,

[0070] Guide rollers are provided on both sides of the beginning of the material channel 5 to guide the T-shaped guide rail to convey the material into the material channel 5 in the correct posture.

[0071] In one embodiment,

[0072] An automatic feeding device is provided at the front end of the aforementioned material channel 5. This automatic feeding device can automatically input the T-shaped guide rail into the center position of the fixture 6.

[0073] An automatic feeding device for T-shaped guide rails is arranged near the material channel 5 on one side of the large back milling machine (this automatic feeding device is existing technology, and its detailed structure will not be described here). The automatic feeding device transports the T-shaped guide rails to the processing position of the material channel 5 one by one. After one end of the T-shaped guide rail is processed, the automatic feeding device is restarted to continue to transport the T-shaped guide rail forward, docking with the auxiliary conveying mechanism 7. The auxiliary conveying mechanism 7 then unloads the processed T-shaped guide rails or allows them to enter the next processing step.

[0074] In summary:

[0075] The fixture 6 of this utility model achieves precise positioning and clamping of the T-shaped guide rail. The upper clamping cylinder 61 and the side clamping cylinder 62 position and clamp the T-shaped guide rail from two directions, ensuring its stability during processing and significantly improving processing accuracy.

[0076] This utility model has stable milling power. The first milling power head 3 and the second milling power head 4 are driven by independent motors, which can stably complete the milling task of the T-shaped guide rail. The first milling power head 3 and the second milling power head 4 respectively mill the upper surface and end face of the T-shaped guide rail, improving the flatness and dimensional accuracy of the machined surface.

[0077] The auxiliary conveying mechanism 7 of this utility model realizes the automated conveying of T-shaped guide rails. At the same time, it moves synchronously with the slide table 2 and is arranged at the end of the material channel 5 and is collinear with the material channel, so that the conveying and processing of T-shaped guide rails can be seamlessly connected, improving production efficiency and greatly shortening the production cycle.

[0078] The special machine of this utility model has a compact layout. By adjusting the parameters of the two milling power heads, the positioning method of the fixture 6 and the auxiliary transmission mechanism 7, it can adapt to the processing of T-shaped guide rails of different sizes and specifications, and meet diverse production needs.
