All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1

[0029] As Figure 1 shown, a machine tool bus control system includes a numerical control operation host 2, the numerical control operation host 2 is rotationally connected to an outer support assembly 5, the bottom end of the outer support assembly 5 is horizontally slidably installed on the front panel 41 of the chassis 4, a split observation window 42 is slidably installed in the middle of the front panel 41, and a main machine box is embedded in the top of the front panel 41; an industrial control main board 1 and an IO board 3 are installed inside the main machine box;

[0030] The IO board 3 is internally provided with a CB104 connector, a CB105 connector, a CB106 connector, a CB107 connector, a JA3 connector, a JD1A connector, and a JD1B connector; the signal output end of the industrial control main board 1 is connected to the JD1A interface of the numerical control operation host 2 through a data cable; the back of the numerical control operation host 2 is provided with a JA41 connector, a JD51 connector, a JA40 connector, a JD36B connector, a JD36A connector, and a JA2 connector; the JD1B connector is connected to the JD51 connector through a wire harness.

[0031] In the above wiring method, the industrial control main board 1 is directly connected to the JD1A interface of the IO unit, and the IO unit is connected to the JD51 interface of the numerical control operation host 2 through the JD1B interface. In this way, the two interfaces CB105 and CB107 of the IO unit are not occupied. A total of 4 interfaces, namely CB104 - CB107, of the IO unit, with 96 input points and 64 output points, are used for the machine tool design. This doubles the number of usable points compared to the original, solves the design difficulty, enables the PLC to make a unified plan, and can solve the wiring scheme of the machine tool without adding another IO unit, thus improving the competitiveness of the enterprise.

[0032] Embodiment 2

[0033] In order to meet the requirements of the fast movement and convenient operation of the numerical control operation host 2 while implementing the above wiring, the following design is given:

[0034] As Figure 2 and Figure 3 shown, the outer support assembly 5 includes a column 51, a bending frame 52, a positioning sleeve 53, and a sliding assembly 54; a sliding assembly 54 is provided on the inner wall of the bottom end of the column 51, and the top end is rotatably connected to a Z-shaped bending frame 52. A positioning sleeve 53 is provided on the side wall of the bending frame 52, and a horizontally arranged numerical control operation host 2 is rotatably installed inside the positioning sleeve 53; a horizontally distributed moving groove 411 is opened at the bottom of the front panel 41, and the sliding assembly 54 is slidably embedded in the moving groove 411; one end of the wire harness passes through the sliding assembly 54, the column 51, and the bending frame 52 and is electrically connected to the numerical control operation host 2 at one end, the outer wall of the wire harness is fixedly connected to the sliding assembly 54, and the other end of the wire harness is electrically connected to the IO board 3.

[0035] The bending frame 52 includes a first vertical section, a horizontal section, and a second vertical section. The first vertical section, the horizontal section, and the second vertical section are integrally formed in a Z-shaped structure. The first vertical section is rotatably installed at the top end of the column 51, and a positioning sleeve 53 is provided on the side wall of the second vertical section;

[0036] Through the above structural design, the adjustment of the numerical control operation host 2 can have three degrees of freedom. The sliding assembly 54 can slide along the moving groove 411, the bending frame 52 can rotate around the column 51, and the numerical control operation host 2 can rotate around the positioning sleeve 53; the two rotation joints are constrained and positioned by means of damping friction;

[0037] As Figures 4 - 7As shown in the figure, at the relative position of the inner wall of the front panel 41 and the moving groove 411, there is a strip-shaped guiding cover 7. The inner wall of the guiding cover 7 is provided with insertion holes 71 distributed in a horizontal linear array. The inner end of the sliding assembly 54 slides into the guiding cover 7. The locking rod 9 horizontally slides through the upright column 51 and the sliding assembly 54, and the locking rod 9 moves inward and inserts into the insertion hole 71 to fix the sliding assembly 54 in the guiding cover 7. The locking rod 9 includes an outer movable column 91, a spring 92, and an insertion rod 93. A horizontal first central hole 511 is provided inside the upright column 51, and a horizontal second central hole 5411 is provided inside the sliding assembly 54. The first central hole 511 and the second central hole 5411 are coaxially arranged. The inner diameter of the first central hole 511 is larger than the inner diameter of the second central hole 5411. The outer movable column 91 and the insertion rod 93 are connected as a whole. The outer diameter of the outer movable column 91 is larger than the outer diameter of the insertion rod 93. The outer movable column 91 fits and slides into the first central hole 511. The insertion rod 93 slides through the second central hole 5411 and one end of the insertion rod 93 extends into the first central hole 511. A spring 92 is sleeved on the part of the insertion rod 93 extending into the first central hole 511. One end of the spring 92 is connected to the outer movable column 91 and the other end abuts against the inner end step surface of the first central hole 511.

[0038] The guiding cover 7 can support and guide the movement process of the outer support assembly 5, making the lateral movement of the outer support assembly 5 more stable. After moving to the designated position, insert the locking rod 9 so that the inner end of the insertion rod 93 is inserted into the slot, and the constraint positioning can be realized.

[0039] As Figure 6 and Figure 7 As shown in the figure, as an improvement of the above technical solution, the bottom outer wall of the upright column 51 is hinged with a foot pedal 6 and a torsion spring is installed at the hinge connection. A semi-circular retaining ring 61 is provided on the surface of the foot pedal 6. The restoring force of the torsion spring is greater than the restoring force of the spring 92. A horizontal support plate 542 is provided at the bottom of the upright column 51.

[0040] The foot pedal 6 in the unfolded state: The foot pedal 6 abuts against the support plate 542, and the spring 92 drives the insertion rod 93 away from the insertion hole 71.

[0041] The foot pedal 6 in the retracted state: The retaining ring 61 squeezes the locking rod 9 to retract, the movable column compresses the spring 92, and the insertion rod 93 is inserted into the insertion hole 71.

[0042] With the above design of the foot pedal 6, on the one hand, it is convenient for workers to push the outer support assembly 5 to move. Workers can stand and operate, adjusting the bending frame 52 and the numerical control operation host 2 with both hands and pushing the foot pedal 6 with their feet to quickly adjust the position of the numerical control operation board. On the other hand, with the cooperative design of the torsion spring and the spring 92, it can be realized that stepping on the foot pedal 6 unlocks and releasing the foot pedal 6 locks. The unlocking and locking processes can be linked with the foot adjustment process, eliminating the need for workers to bend down separately to lock or unlock, resulting in higher adjustment efficiency.

[0043] As an improvement of the above technical solution, the sliding assembly 54 includes a slider 541 and a baffle 512. The baffle 512 is provided on the outer wall of the middle part of the slider 541. One end of the slider 541 is vertically and fixedly connected to the column 51. The front panel 41 is fitted between the column 51 and the baffle 512. The second central hole 5411 is opened in the slider 541. The slider 541 and the baffle 512 are slidably embedded in the guide cover 7. The baffle 512 can be configured with the column 51 to achieve restraint positioning.

[0044] Embodiment 3

[0045] To enable the cable to adapt to the adjustment requirements of the outer support assembly 5, the following structural design is given:

[0046] As Figure 5 shown, a wire harness storage assembly 8 is provided on the inner side of the front panel 41. The wire harness storage assembly 8 includes a fixing plate 81, a first side plate 82, a second side plate 83, and a weight roller 86. A vertical groove 811 is opened at the midline of the fixing plate 81. The first side plate 82 and the second side plate 83 are symmetrically provided on both sides of the vertical groove 811. The weight roller 86 is vertically and slidably embedded in the vertical groove 811. The wire harness passes under the weight roller 86 in a U shape. The fixing plate 81 is fixedly connected to the front panel 41. An extension plate 84 extends upward from the top of the fixing plate 81. The extension plate 84 is vertically provided with a clamping plate 85, and the clamping plate 85 clamps and positions the wire harness.

[0047] When adjusting the outer support assembly 5 at one end, the wire harness 9a will be pulled outwards, flattening the wire harness 9a. The weight roller 86 is lifted upward by the wire harness. When resetting, the weight roller 86 moves downward to reset, thereby realizing the automatic storage of the wire harness and enabling the redundant part of the cable to be flattened and stored.

[0048] When implementing the above Embodiment 2 and Embodiment 3:

[0049] When the numerical control operation host 2 needs to be used, step on the foot pedal 6. The foot pedal 6 rotates downward and compresses the torsion spring. The spring 92 drives the outer movable column 91 to extend and reset. The insertion rod 93 leaves the jack 71. Then the worker can push the sliding assembly 54 to move along the guide cover 7 through the foot pedal 6. Then rotate the adjusting bending frame 52 and the numerical control operation host 2. During the movement, the wire harness is pulled out, and the wire harness drives the weight roller 86 to move upward along the vertical groove 811.

[0050] When it is not used and needs to be reset, push the outer support component 5 back, the heavy roller 86 presses down on the wire harness to form a U-shaped structure, both feet leave the foot pedal 6, the torsion spring drives the foot pedal 6 to rotate upward, the retaining ring 61 abuts against the movable column and contracts inward, the movable column compresses the spring 92, and the inner end of the inserting rod 93 is inserted into the jack 71.
