Description

Technical Field

[0001] This application relates to the field of PCB CNC drilling machines, and in particular to a spindle transverse movement structure for a PCB CNC drilling machine. Background Technology

[0002] PCB CNC drilling machines are specialized equipment for producing PCBs (Printed Circuit Boards). PCB manufacturing demands high speed, high precision, high stability, and intelligent operation from the equipment. Currently, most PCB CNC drilling machines use linear motors for their X-axis mechanical transmission. A mounting plate is mounted on the linear motor, and multiple spindle modules are then mounted on the mounting plate. These modules are connected via a single mounting plate. This results in a large overall size of the mounting plate, leading to a heavy load on the linear motor and consequently affecting its lifespan. Utility Model Content

[0003] To improve the service life of the motor, this application provides a lateral movement structure for the spindle of a PCB CNC drilling machine.

[0004] This application provides a PCB CNC drilling machine spindle transverse movement structure, which adopts the following technical solution:

[0005] A lateral movement structure for a PCB CNC drilling machine spindle includes a crossbeam, a linear motor, and a mounting plate. The mounting plate is slidably connected to the crossbeam along its length. The linear motor is mounted on the crossbeam to drive the mounting plate to slide. The crossbeam has several base plates distributed along its length. Each base plate is slidably connected to the crossbeam along its length. A spindle module is mounted on each base plate. The mounting plate has connecting rods for connecting to the base plates.

[0006] By adopting the above technical solution, the linear motor drives the mounting plate to slide, and the mounting plate is connected to the base plate through a connecting rod. Compared with the prior art, this connection method can reduce the size of the mounting plate, thereby reducing the load on the linear motor and increasing the service life of the linear motor.

[0007] Optionally, a slide rail is provided on the crossbeam, the length direction of the slide rail is parallel to the length direction of the crossbeam, and a first slider is provided on the mounting plate, the first slider being slidably connected to the slide rail.

[0008] By adopting the above technical solution, a slide rail is provided on the crossbeam, and the mounting plate is slidably connected to the slide rail through the first sliding block, thereby realizing the sliding connection.

[0009] Optionally, two slide rails are provided, which are distributed vertically, and several first sliders are provided and distributed on the upper and lower sides of the mounting plate.

[0010] By adopting the above technical solution, two slide rails are provided, and the upper and lower sides of the mounting plate are connected to the two slide rails, thereby improving the stability of the sliding of the mounting plate.

[0011] Optionally, the mounting plate is provided with a plurality of positioning rods, and the connecting rod is provided with a plurality of positioning holes for the positioning rods to be inserted.

[0012] By adopting the above technical solution, the mounting plate can be connected to the connecting rod via the positioning rod, which facilitates the connection between the mounting plate and the connecting rod.

[0013] Optionally, the connecting rod is provided in two sets, and the two sets of connecting rods are respectively connected to several base plates on both sides of the linear motor.

[0014] By adopting the above technical solution, two sets of connecting rods are provided, and the two connecting rods are respectively connected to the base plates on both sides to improve the convenience of installation.

[0015] Optionally, a positioning plate is provided on the side of the mounting plate near the crossbeam. When the mounting plate is connected to the two sets of connecting rods, the end face of the connecting rod abuts against the positioning plate.

[0016] By adopting the above technical solution, the connecting rod and the base plate are installed first, and then the mounting plate is installed. When installing the mounting plate, the connecting rods on both sides are abutted against the two sides of the positioning plate, thereby limiting the relative position of the connecting rod and the mounting plate along the length of the beam, which facilitates the connection of the mounting plate and the connecting rod.

[0017] Optionally, the positioning plate has positioning grooves on both sides distributed along the length of the crossbeam, and the connecting rod can be slidably locked in the positioning grooves.

[0018] By adopting the above technical solution, the connecting rod is locked in the positioning groove on the positioning plate. Then, the mounting plate is pushed to move closer to the connecting rod, which makes it easier for the positioning rod to be locked in the positioning hole, thereby improving the convenience of installation.

[0019] Optionally, several steel balls are rotatably connected to both the upper and lower side walls of the positioning groove, and the several steel balls are distributed along the extension direction of the positioning groove.

[0020] By adopting the above technical solution, steel balls are provided to facilitate the sliding of the end of the connecting rod within the positioning groove.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The linear motor drives the mounting plate to slide, and the mounting plate is connected to the base plate through a connecting rod. Compared with the existing technology, this connection method can reduce the size of the mounting plate, thereby reducing the load on the linear motor and increasing the service life of the linear motor.

[0023] 2. The connecting rod is locked in the positioning groove on the positioning plate. Then, the mounting plate is pushed towards the connecting rod, which makes it easier for the positioning rod to be locked in the positioning hole, thereby improving the convenience of installation.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] Example 1:

[0032] Embodiment 1 of this application discloses a lateral movement structure for the spindle of a PCB CNC drilling machine. (Refer to...) Figure 1 and Figure 2 The system includes a crossbeam 1, a linear motor 4, and a mounting plate 2. The linear motor 4 is fixedly mounted on the side of the crossbeam 1. Two slide rails 11 are fixedly mounted on the crossbeam 1. The two slide rails 11 are distributed vertically and their length direction is parallel to the length direction of the crossbeam 1. Two first sliders 21 are fixedly connected to the upper and lower sides of the mounting plate 2. The two first sliders 21 are distributed along the length direction of the slide rails 11 and are slidably connected to the two slide rails 11 respectively. The linear motor 4 is fixedly connected to the mounting plate 2 to drive the mounting plate 2 to move.

[0033] Reference Figure 1 and Figure 2 The crossbeam 1 is located on both sides of the mounting plate 2, and several base plates 3 are provided. The base plates 3 are distributed along the length of the crossbeam 1, and the spindle module 31 is fixedly installed on the base plate 3. The upper and lower ends of the base plate 3 are fixedly connected to the second slider 32, and the two second sliders 32 are respectively slidably connected to the two slide rails 11.

[0034] Reference Figure 1 and Figure 2 The mounting plate 2 is provided with two sets of connecting rods 5, which are fixedly connected to the mounting plate 2 by bolts. The two connecting rods 5 are distributed on both sides of the mounting plate 2 and are respectively connected to the base plates 3 on both sides. Each set of connecting rods 5 includes two connecting rods 5, which are distributed in the vertical direction. The connecting rods 5 are fixedly connected to several base plates 3 in sequence.

[0035] Reference Figure 3 The mounting plate 2 is fixedly connected with several positioning rods 22, and the connecting rod 5 has several positioning holes 51 for the positioning rods 22 to be inserted.

[0036] The implementation principle of Embodiment 1 of this application is as follows: the linear motor 4 drives the mounting plate 2 to slide, and the mounting plate 2 is connected to the base plate 3 through the connecting rod 5. Compared with the prior art, this connection method can make the size of the mounting plate 2 smaller, thereby reducing the load on the linear motor 4 and improving the service life of the linear motor 4.

[0037] Example 2:

[0038] The difference between Example 2 and Example 1 is that, referring to Figure 4 and Figure 5 Two positioning plates 23 are fixedly connected to the side of the mounting plate 2 near the crossbeam 1. The two positioning plates 23 are distributed vertically and correspond to the connecting rods 5 on the upper and lower sides respectively. Positioning grooves 231 are provided on both sides of the positioning plates 23 along the length of the crossbeam 1, and the length direction of the positioning grooves 231 is distributed along the thickness direction of the mounting plate 2. When the mounting plate 2 is connected to the two sets of connecting rods 5, the ends of the connecting rods 5 slide and engage in the positioning grooves 231.

[0039] Reference Figure 4 and Figure 5 The upper and lower side walls of the positioning groove 231 are rotatably connected with several steel balls 232. The steel balls 232 are distributed along the extension direction of the positioning groove 231. When the connecting rod 5 is located in the positioning groove 231, the connecting rod 5 is located between two steel balls 232 and abuts against the steel balls 232.

[0040] The implementation principle of Example 2 is as follows: the connecting rod 5 is engaged in the positioning groove 231 on the positioning plate 23, and then the mounting plate 2 is pushed to move closer to the connecting rod 5, so that the positioning rod 22 can be engaged in the positioning hole 51, thereby improving the convenience of installation.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
