[0002] Elevator guide rails are elevator components consisting of steel rails and connecting plates. While providing guidance, the guide rails also bear the impact force of the car and the elevator during braking. Elevator guide rails are mostly fixed by interlocking male and female tenons.

[0003] Our company has designed a CNC tenon and mortise integrated machining machine (application number CN202210765756.X). This machine has the following drawbacks during its machining process: 1. The machine has a large structural size, high cost, and large footprint; 2. Loading and unloading elevator guide rails on the same side of the machine results in low production efficiency; 3. Existing fixtures cannot independently adjust their alignment with the machine, requiring disassembly and reinstallation, which is quite difficult. This technical problem urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, the purpose of this utility model is to provide a machine tool for machining male and female tenons of elevator T-shaped guide rails. It features double-sided loading and unloading, resulting in high production efficiency.

[0016] In a preferred embodiment of the present invention, a linear guide rail is provided between the fixture seat and the machine tool base. A geared motor is installed on the machine tool base on one side of the fixture seat. The output end of the geared motor is connected to a lead screw transmission assembly. The fixture seat is installed on the lead screw transmission assembly and is driven by the geared motor to reciprocate along the linear guide rail.

[0017] In a preferred embodiment of the present invention, the supporting component includes a U-shaped bracket for through which a T-shaped guide rail passes, and a pair of tapered rollers rotatably mounted in the U-shaped bracket, the tapered rollers being used to support the T-shaped guide rail.

[0018] In a preferred embodiment of the present invention, a through groove for installing a rotating component is provided on the column, and the through groove is arranged perpendicularly to the guide groove.

[0019] The rotating assembly includes an electric roller arranged along the through-slot direction, a support frame rotatably mounted at both ends of the electric roller, and a cylinder for connecting the support frame. The cylinder is mounted on a column and its telescopic end can drive the electric roller to move vertically. The telescopic extension of the cylinder drives the electric roller to contact the upper surface of the T-shaped guide rail and converts the rotational motion of the electric roller into the horizontal movement of the T-shaped guide rail.

[0020] In a preferred embodiment of the present invention, an automatic feeding device is provided at the front end of both fixtures, and the automatic feeding device can automatically input or output the T-shaped guide rail to the center position of the fixture.

[0048] 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.

[0049] like Figure 1-2 As shown, this utility model provides a machine tool for processing male and female tenons of elevator T-shaped guide rails, including a machine tool base 1;

[0050] A column 2 is installed on the base 1 of the machine tool, and slides 3 are installed on both sides of the column 2 along its longitudinal direction. A tenon milling head 4 is installed on one slide 3, and a tenon milling head 5 is installed on the other slide 3.

[0051] On the machine tool base 1, there are clamps 6 for holding T-shaped guide rails at both ends, and material channels 7 are installed on the side of the clamps 6 away from the column 2.

[0052] At the bottom of the aforementioned column 2, a guide groove 21 through which a T-shaped guide rail passes is provided. A support component 8 for supporting the T-shaped guide rail is installed in the guide groove 21. The support component 8 is collinear with the material channel 7, and at least two sets of the support component 8 are arranged.

[0053] A rotating assembly 9 for driving the displacement of the T-shaped guide rail is installed in the aforementioned guide groove 21, and the rotating assembly 9 is arranged between the supporting assemblies 8.

[0054] The working principle and beneficial effects of the above embodiments are as follows:

[0055] This utility model uses a clamp 6 to hold and fix the T-shaped guide rail. The material channel 7 is located on the side of the clamp 6 away from the column 2 and is used to place the T-shaped guide rail to be processed, which facilitates the feeding and discharging of the T-shaped guide rail.

[0056] The T-shaped guide rail is fed into the tenon milling head 4 via the material channel 7 and clamped and fixed by the fixture 6. The tenon milling head 4 moves vertically along the slide table 3 to process the T-shaped guide rail. After processing, the T-shaped guide rail continues to be conveyed forward into the column 2. The rotating component 9 and the supporting component 8 work together to convey the T-shaped guide rail to the position of the tenon milling head 5. Another fixture 6 clamps the T-shaped guide rail. The tenon milling head 5 moves vertically along the slide table 3 on the other side to process the T-shaped guide rail again. After processing, the T-shaped guide rail is unloaded via the material channel 7 on the other side.

[0057] When the T-shaped guide rail moves to the position of the tenon milling head 4, the tenon milling head 4 performs tenon milling on the guide rail; then the T-shaped guide rail continues to move to the position of the tenon milling head 5, and the tenon milling head 5 performs tenon milling on the guide rail. Through this processing technology, the tenon and tenon processing of the T-shaped guide rail can be completed on the same machine tool, reducing the number of clamping operations and the transfer time between machine tools, and improving processing efficiency.

[0058] This utility model provides a guide groove 21 inside the column 2, and a support component 8 and a rotating component 9 are designed inside the guide groove 21. The support component 8 can ensure that the T-shaped guide rail maintains a stable position and posture during the processing, while the rotating component 9 can precisely drive the guide rail to move and ensure the movement accuracy, thereby improving the processing accuracy of the male and female tenons.

[0059] In one embodiment,

[0060] like Figure 3-4 As shown, one tenon milling head 4 is provided, and a protrusion for milling the tenon part of the T-shaped guide rail is provided on the head of the tenon milling head 4.

[0061] Two of the aforementioned tenon milling heads 5 are provided, which are symmetrically arranged on both sides of the T-shaped guide rail of the tenon to be processed.

[0062] In one embodiment,

[0063] like Figure 5-6 As shown, the above-mentioned clamp 6 includes a clamp seat 61 that can move horizontally back and forth, a side clamping assembly 62 arranged in the clamp seat 61, and an upper clamping assembly 63 mounted on the clamp seat 61.

[0064] The aforementioned side clamping assembly 62 includes a side clamping cylinder 621, a rack 622 driven by the side clamping cylinder 621 to move horizontally back and forth, a gear 623 meshing with the rack 622, a left slider 624 connected to the gear 623, and a right slider 625 driven by the side clamping cylinder 621 to move horizontally back and forth.

[0065] The aforementioned upper clamping assembly 63 includes a support 631 mounted on a clamping base 61, an upper clamping cylinder 632 mounted on the support 631, and an upper pressure head 633 driven by the upper clamping cylinder 632 to move vertically back and forth.

[0066] The fixture seat 61 is adjusted to the center position according to the specifications of the T-shaped guide rail. The side clamping cylinder 621 is activated, pushing the rack 622 to move horizontally. Through the rotation of the gear 623, the left slider 624 and the right slider 625 move towards each other, clamping both sides of the T-shaped guide rail. At the same time, the upper clamping cylinder 632 is activated, pushing the upper pressure head 633 to move vertically downward, pressing the upper surface of the T-shaped guide rail, further fixing the guide rail, and ensuring that the T-shaped guide rail is firmly clamped in both the horizontal and vertical directions to prevent movement during processing.

[0067] In one embodiment,

[0068] A linear guide rail is provided between the fixture seat 61 and the machine tool base 1. A geared motor 64 is installed on the machine tool base 1 on one side of the fixture seat 61. The output end of the geared motor 64 is connected to the lead screw transmission assembly. The fixture seat 61 is installed on the lead screw transmission assembly and is driven by the geared motor 64 to move back and forth along the linear guide rail, thereby adjusting the centering position of the fixture seat 61 relative to the machine tool base 1.

[0069] Before processing, according to the specifications and dimensions of the T-shaped guide rail, the screw transmission assembly is driven by the geared motor 64 to make the fixture seat 61 move horizontally along the linear guide rail. The position of the fixture seat 61 is adjusted to align it with the machining center of the machine tool, thereby reducing subsequent processing errors and improving the machining accuracy of the male and female tenons.

[0070] In one embodiment,

[0071] like Figure 7 As shown, the support assembly 8 includes a U-shaped bracket 81 for passing through the T-shaped guide rail, and a pair of tapered rollers 82 rotatably installed in the U-shaped bracket 81. The tapered rollers 82 are used to support the T-shaped guide rail. The U-shaped bracket 81 is made by welding and has high structural strength and stability.

[0072] The U-shaped bracket 81 is used to install the tapered rollers 82 and bear the weight of the T-shaped guide rail. The tapered rollers 82 are arranged in pairs inside the U-shaped bracket 81 to support the T-shaped guide rail. The design of the tapered rollers 82 enables the T-shaped guide rail to automatically center when passing through, reducing the friction between the T-shaped guide rail and the tapered rollers 82 and ensuring the smooth movement of the T-shaped guide rail.

[0073] In one embodiment,

[0074] like Figure 8-9 As shown, a through groove 22 for mounting the rotating component 9 is provided on the column 2, and the through groove 22 is arranged perpendicularly to the guide groove 21.

[0075] The aforementioned rotating assembly 9 includes an electric roller 91 arranged along the through direction of the through slot 22, a support frame 92 rotatably mounted at both ends of the electric roller 91, and a cylinder 93 connected to the support frame 92. The cylinder 93 is mounted on the column 2 and its telescopic end can drive the electric roller 91 to move vertically. The telescopic extension of the cylinder 93 drives the electric roller 91 to contact the upper surface of the T-shaped guide rail and converts the rotational motion of the electric roller 91 into the horizontal movement of the T-shaped guide rail.

[0076] A through groove 22 is provided on the column 2. The through groove 22 is arranged perpendicularly to the guide groove 21 to provide space for the installation and movement of the rotating component 9. At the same time, it ensures that the movement direction of the rotating component 9 is perpendicular to the movement direction of the T-shaped guide rail, which facilitates precise driving.

[0077] The electric roller 91 is driven to rotate by a motor. Its surface contacts the upper surface of the T-shaped guide rail, and its rotational motion is converted into the horizontal movement of the T-shaped guide rail through friction.

[0078] The cylinder 93 drives the electric roller 91 to move vertically. Through the extension and retraction of the cylinder 93, the electric roller 91 can contact or separate from the upper surface of the T-shaped guide rail, and can adapt to T-shaped guide rails of various specifications.

[0079] In one embodiment,

[0080] like Figure 10 As shown, an automatic feeding device is provided at the front end of both of the above-mentioned clamps 6. The automatic feeding device can automatically input or output the T-shaped guide rail to the center position of the clamp 6.

[0081] The automatic feeding device automatically feeds the T-shaped guide rail into the material channel 7 and clamps it with the fixture 6. The tenon milling head 4 performs tenon milling on the guide rail. After the processing is completed, the fixture 6 releases the T-shaped guide rail, and the automatic feeding device starts again, feeding the T-shaped guide rail into the support component 8 in the guide groove 21. The drive rotating component 9 feeds the T-shaped guide rail into the automatic feeding device at the tenon milling station. The automatic feeding device at the tenon milling station drives the T-shaped guide rail in the reverse direction and delivers it into place. It is clamped by another fixture 6, and the tenon milling head 5 performs tenon milling on the guide rail. After the processing is completed, the automatic feeding device at this station drives the T-shaped guide rail to unload in the forward direction.

[0082] The automatic feeding device can automatically process the two T-shaped guide rails. One T-shaped guide rail is used for the female tenon, and the other T-shaped guide rail is used for the male tenon, so that the female and male tenon milling of the machine tool can be carried out simultaneously, which further improves the processing efficiency of the machine tool.

[0083] The automatic feeding device is existing technology and is not the invention point of this utility model. It is only used to explain the working principle of this utility model, so its specific structure will not be described in detail.

[0084] In one embodiment,

[0085] like Figure 11 As shown, a limiting member is installed on both of the above-mentioned slides 3. The limiting member moves vertically with the slide 3 and is arranged facing the above-mentioned clamp 6.

[0086] The design of the limiting component allows the T-shaped guide rail to be precisely displaced to the machining position of the male and female tenons, ensuring cutting accuracy.

[0087] In one embodiment,

[0088] A counterweight cylinder is installed on the column 2. The telescopic end of the counterweight cylinder is connected to the slide 3. The telescopic direction of the counterweight cylinder is consistent with the displacement direction of the slide. The telescopic action of the counterweight cylinder can directly counteract the gravity effect generated by the slide 3 during vertical movement, ensuring that the slide 3 moves smoothly and without shaking.

[0089] In summary:

[0090] This utility model discloses a machine tool for machining male and female tenons of elevator T-shaped guide rails. When the T-shaped guide rail moves to the position of the male tenon milling head, the male tenon milling head mills the male tenon of the guide rail. Subsequently, the T-shaped guide rail continues to move to the position of the female tenon milling head, and the female tenon milling head mills the male tenon of the guide rail. The machining of male and female tenons of the T-shaped guide rail can be completed on the same machine tool, reducing the number of clamping operations and the transfer time between machine tools, and improving machining efficiency.

[0091] This utility model opens a guide groove in the column, and designs a support component and a rotating component in the guide groove. The support component can ensure that the T-shaped guide rail maintains a stable position and posture during the processing, while the rotating component can accurately drive the guide rail from the male tenon processing position to the female tenon processing position, and ensure the displacement accuracy of the guide rail, thereby improving the processing accuracy of the male and female tenons of the T-shaped guide rail.

[0092] This utility model designs a single column for both the male and female tenon milling heads, and arranges a support component and a rotating component inside the column to enable rapid transfer of the T-shaped guide rail at the male and female tenon machining positions. This makes the overall structure of the machine tool compact and reasonable, optimizes space utilization, reduces the machine tool's floor space, and improves the machine tool's processing efficiency.

[0093] The fixture base of this invention achieves rapid centering adjustment through a geared motor and a lead screw transmission assembly, and the slide table achieves rapid and stable vertical movement through a counterweight cylinder, enabling the machine tool to quickly adapt to the processing needs of guide rails of different specifications.
