The elevator guide rail processing machine is mainly used to process elevator guide rails. When in use, the raw material needs to be fixed on the base, and the raw material moves with the base. The planing device on the gantry planer is used to plan the raw material into the shape of the guide rail. The raw material needs to be clamped and aligned before processing. The elevator guide rail processing machine in the prior art generally uses a gear rack structure to center and fix multiple elevator guide rails, and controls the opening and closing of the chuck by the cylinder, and each cylinder controls three chucks. However, this structure is very complicated, with too many parts, and the matching relationship between the parts is complicated. The cost is high and the amount of later maintenance is large. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides an auxiliary equidistant alignment device used when a gantry planer is used to process elevator guide rails, so as to overcome the deficiencies in the prior art.
[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:
[0005] The invention discloses an auxiliary equidistant alignment device used for machining elevator guide rails by a gantry planer, comprising a lifting frame, an assembly frame and a bottom frame which are sequentially arranged from high to low and are fixed together by connecting rods.
[0006] The assembly frame is provided with a centering mechanism, which includes a servo stepper motor and a plurality of fixture units arranged side by side at even intervals;
[0007] The clamp unit comprises a driving screw and a guide rod which are arranged in parallel up and down, and a pair of clamping plates which are arranged on the driving screw and the guide rod at intervals on the left and right sides; the driving screw is connected to the output shaft of the servo stepper motor, and the guide rod passes through the centering mechanism and is fixed on the assembly frame;

[0009] The driving screw is provided with positive threads and negative threads at intervals on the left and right sides, and the pair of clamps includes a positive clamp and a negative clamp, the screw sleeve in the first assembly hole of the positive clamp is screwed to the positive thread on the driving screw, and the screw sleeve in the first assembly hole of the negative clamp is screwed to the negative thread on the driving screw.
[0010] Furthermore, a screw coupler is provided between two adjacent clamp units, and threads are provided at both ends of the screw coupler corresponding to the threads on the drive screw; the screw coupler couples and docks the drive screw in the previous clamp unit with the drive screw in the next clamp unit.
[0011] Furthermore, a limit buffer assembly is arranged on the guide rod between two adjacent clamp units; the limit buffer assembly includes a limit block, a buffer block and a buffer spring, the limit block is fixedly arranged on the guide rod, the buffer block is slidably arranged on the guide rod, and the buffer spring is sleeved on the guide rod and is located between the limit block and the buffer block.
[0012] Furthermore, locking studs are respectively provided at both ends of the screw coupler.
[0013] Preferably, a docking flange is provided on the lifting frame.

[0018] Compared with the prior art, the beneficial effects of the utility model are:
[0019] 1) In this case, an auxiliary equidistant alignment device is used for machining elevator guide rails on a gantry planer. By setting positive threads and negative threads on the driving screw, a positive clamping plate and a negative clamping plate are driven to clamp multiple T-shaped elevator guide rails placed at intervals on the gantry planer, so that the multiple T-shaped elevator guide rails are equidistant and aligned.

[0031] See also Figure 1-5 The utility model provides an auxiliary equidistant alignment device used for machining elevator guide rails on a gantry planer, comprising a lifting frame 1, an assembly frame 2 and a base frame 3 which are arranged in sequence from high to low, the lifting frame 1, the assembly frame 2 and the base frame 3 are connected and fixed into one body through a connecting rod, a centering mechanism is arranged on the assembly frame 2, and the centering mechanism comprises a servo stepper motor 4 and a plurality of fixture units 5 which are evenly spaced and arranged side by side.
[0032] The clamp unit 5 includes a driving screw 51 and a guide rod 52 which are arranged in parallel up and down, and a pair of clamping plates 53 which are arranged on the driving screw 51 and the guide rod 52 at intervals on the left and right; the driving screw 51 is connected to the output shaft of the servo stepper motor 4, and the guide rod 52 passes through the centering mechanism and is fixed on the assembly frame 2.
[0033] The clamping plate 53 has a first assembly hole 531 and a second assembly hole 532 spaced apart above and below; a screw sleeve 533 is fixedly arranged in the first assembly hole 531, and the driving screw 51 passes through the first assembly hole 531 and is threadedly connected to the screw sleeve 533; the guide rod 52 passes through the second assembly hole 532 and is fixedly connected to the assembly frame 2.
[0034] Specifically, the driving screw 51 is provided with a positive thread 511 and a negative thread 512 at intervals on the left and right sides, and the pair of clamps 53 include a forward clamp 53A and a negative clamp 53B, the screw sleeve 533 in the first assembly hole 531 of the forward clamp 53A is screwed to the positive thread 511 on the driving screw 51, and the screw sleeve 533 in the first assembly hole 531 of the negative clamp 53B is screwed to the negative thread 512 on the driving screw 51, so that when the servo stepper motor 4 drives the driving screw 51 to rotate forward, the forward clamp 53A and the negative clamp 53B move closer to each other, thereby clamping the vertical plate of the T-type elevator guide rail 9; when the servo stepper motor 4 drives the driving screw 51 to reverse, the forward clamp 53A and the negative clamp 53B move away from each other, thereby loosening the vertical plate of the T-type elevator guide rail 9.
[0035] Furthermore, since the multiple clamp units 5 are all driven by a servo stepper motor 4, they are multi-stage linkage. If a traditional single drive screw is used, the position of the drive screw 51 will deviate after long-term operation, and the deviation will be amplified in multiple stages, resulting in inaccurate travel of the clamping plate 53 in each clamp unit 5. Therefore, a screw coupler 6 is provided between two adjacent clamp units 5, and threads are provided at both ends of the screw coupler 6 to correspond to the threads on the drive screw 51; the screw coupler 6 couples and docks the drive screw 51 in the previous clamp unit 5 with the drive screw 51 in the next clamp unit 5. In actual applications, a gap is provided between the driving screw 51 in the previous clamp unit 5 and the driving screw 51 in the subsequent clamp unit 5. By rotating the screw coupler 6, the distance between the driving screw 51 in the previous clamp unit 5 and the driving screw 51 in the subsequent clamp unit 5 can be adjusted, thereby ensuring that if the position of the driving screw 51 deviates after long-term operation, it is only necessary to adjust the screw coupler 6 so that the forward clamping plate 53A and the reverse clamping plate 53B in each clamp unit 5 can clamp the elevator guide rail 9 and make them equidistant and centered.
[0036] Furthermore, locking studs 61 are respectively provided at both ends of the screw coupler 6 , and tightening the locking studs 61 can fix the driving screw 51 in the screw coupler 6 .
[0037] Furthermore, a limit buffer assembly is provided on the guide rod 52 between two adjacent clamp units 5; the limit buffer assembly includes a limit block 71, a buffer block 72 and a buffer spring 73, the limit block 71 is fixedly provided on the guide rod 52, the buffer block 72 is slidably provided on the guide rod 52, the buffer spring 73 is sleeved on the guide rod 52 and is located between the limit block 71 and the buffer block 72, one end of the buffer spring 73 is connected to the limit block 71, and the other end is connected to the buffer block 72. The limit buffer assembly limits the forward clamping plate 53A and the reverse clamping plate 53B in each clamp unit 5, further ensuring the accuracy of the travel of the forward clamping plate 53A and the reverse clamping plate 53B.
[0038] Furthermore, the servo stepper motor is connected to an encoder (not shown), and the encoder's pulse signal is used to control the forward and reverse signals output by the servo stepper motor 4 per unit time, thereby driving the drive screw 51 to rotate forward and reverse by controlling the servo stepper motor 4 to rotate forward and reverse.
[0039] Preferably, in this embodiment, a docking flange 11 is provided on the lifting frame 1, and the docking flange 11 is used for docking with an external lifting mechanism.
[0040] Preferably, in this embodiment, docking protrusions 31 are symmetrically provided at the four corners of the bottom surface of the base frame 3, and the docking protrusions 31 are used to cooperate with the positioning grooves on the slide seat of the gantry planer, so that the centering device of this case can be positioned on the gantry planer.
[0041] Preferably, in this embodiment, an anti-slip pad 534 is provided on the inner side of the clamping plate 53 that contacts the elevator guide rail 9 .
[0042] The auxiliary equidistant alignment device used in the gantry planer for processing elevator guide rails in this case has the following working principle and process in actual working conditions:
[0043] 1. The centering device is lowered and placed on the slide of a planer (not shown) by a lifting mechanism (not shown). The docking protrusion 31 on the base frame 3 cooperates with the positioning groove on the slide of the planer to position the centering device so that there is an elevator guide rail 9 between the positive clamping plate 53A and the reverse clamping plate 53B of each clamp unit 5.
[0044] 2. The servo stepper motor 4 drives the driving screw 51 to rotate forward, and the forward clamping plate 53A and the reverse clamping plate 53B move closer to each other, thereby clamping the vertical plate of the T elevator guide rail 9, so that each elevator guide rail 9 is equidistantly aligned;
[0045] 3. The servo stepper motor 4 drives the driving screw 51 to reverse, and the positive clamping plate 53A and the reverse clamping plate 53B move away from each other, thereby loosening the vertical plate of the T elevator guide rail 9;
[0046] 4. The centering device is lifted up and away from the slide of the planer by the lifting mechanism. At this time, the multiple elevator guide rails 9 on the slide of the planer have been equidistantly aligned, and the elevator guide rails 9 can be processed in the next step by the planer.
