[0032] The following will further describe the present utility model in detail with reference to the Figures 1-6 accompanying drawings:

[0033] Referring to Figures 1-2 , the present utility model provides a horizontal automatic grinding machine, including:

[0034] A bed base 1, the bed base 1 includes a front bed base 11 and a rear bed base 12, and the front bed base 11 and the rear bed base 12 are arranged in a T shape;

[0035] A workbench 3, the workbench 3 is slidably arranged on the front bed base 11;

[0036] Specifically, the workbench 3 can be moved on the front bed base 11 by means of devices such as a hydraulic transmission rod, a pneumatic transmission rod, a motor 43 screw, a cylinder push rod, etc. Splash guards are provided on both left and right sides of the workbench 3.

[0037] A grinding wheel assembly 4, the grinding wheel assembly 4 is arranged on the rear bed base 12;

[0038] A first driving assembly 5, the first driving assembly 5 is arranged on the rear bed base 12 and drives the grinding wheel assembly 4 to perform a horizontal movement;

[0039] A second driving assembly, the second driving assembly 6 drives the grinding wheel assembly 4 to perform a lifting movement;

[0040] Referring to Figures 3-4 , the grinding wheel assembly 4 includes a frame, a spindle base 44, a spindle 42, a motor 43, and a grinding wheel 41. The spindle 42 passes through the spindle base 44. The motor 43 and the grinding wheel 41 are respectively arranged on both sides of the spindle 42, so that the motor 43 drives the grinding wheel 41 to rotate through the spindle 42. One end of the spindle base 44 is located inside the frame, and linear guide rails 45 are provided on both sides of the frame. The spindle base 44 is slidably arranged on the linear guide rails 45. The first driving assembly 5 is arranged on the side of the frame and drives the frame to perform a horizontal movement. The second driving assembly 6 is arranged on the top of the frame and drives the spindle base 44 to perform a lifting movement.

[0041] Specifically, the motor 43 is connected to the main shaft 42 through a coupling, and the motor 43 is directly fixedly connected to the main shaft seat 44. The main shaft seat 44 located inside the frame is not in contact with the frame. After the main shaft seat 44 extends out of the frame, it extends left and right to form an extension plate, and this extension plate is fixedly connected to the slider on the linear guide 45. Such a setting makes the main shaft seat 44 delicate without external force, and it moves along with the direction of the external force under the action of an external force.

[0042] Referring to Figure 4 , the first driving assembly 5 includes a first driver 51, a first screw 52, a first nut 53, and a fixing plate 54. The fixing plate 54 includes a base plate 541 connected to the side of the frame and a plurality of connecting plates 542 spaced parallel on one side of the base plate 541. Through holes are formed in the connecting plates 542. The first screw 52 passes through the through holes. The first nut 53 is sleeved on the first screw 52, and the first nut 53 is a sleeve-type nut. One end of the first nut 53 is arranged on the connecting plate 542, and the other end passes through the connecting plate 542. When the first driver 51 drives the first screw 52 to rotate, the first nut 53 synchronously drives the fixing plate 54 to move.

[0043] In this embodiment, the first driver 51 is a motor, which is arranged on the rear bed base 12 through a motor seat. The motor is connected to the first screw 52 through a coupling. The first screw 52 passes through the through hole. One end of the first nut 53 has a diameter larger than the diameter of the through hole, and the other end has a diameter smaller than the diameter of the through hole. Therefore, one end of the first nut 53 is connected to the connecting plate 542, and the other end passes through the through hole. When the first driver 51 drives the first screw 52 to make a rotational motion, the first nut 53 makes a linear motion on the first screw 52, and the first nut 53 synchronously drives the fixing plate 54 to move, and then the fixing plate 54 drives the frame to move.

[0044] Furthermore, in order to reduce the friction when the frame moves, linear slide rails 55 are provided on the rear bed base 12. The linear slide rails 55 are symmetrically arranged on both sides of the frame, and a plurality of sliders on the linear slide rails 55 are connected to the fixing plate 54. In order to better connect the fixing plate 54 and the slider, a bottom plate is provided at the bottom end of the fixing plate 54. The bottom plate is respectively connected to the bottom ends of the connecting plates 542, and the bottom surface of the bottom plate is connected to the slider.

[0045] In this embodiment, in order to limit the movement range of the frame, a limiting block is also provided on the rear bed base 12.

[0046] Continuing to refer to Figure 4 , the second driving assembly includes a second driver 61, a second screw 62, and a second nut 63. The second driver 61 is arranged at the top end of the frame. The second screw 62 passes through the frame and extends into the main shaft seat 44. The second nut 63 is sleeved on the second screw 62; the second nut 63 is a sleeve-type nut, one end of which is fixedly arranged on the main shaft seat 44, and the other end extends into the main shaft seat 44.

[0047] In this embodiment, to ensure that the second screw rod 62 does not interfere with the main shaft 42, the second screw rod 62 is arranged close to one side and not in the middle position.

[0048] Furthermore, to reduce the overall height of the device, a U-shaped through groove is formed in the middle of the rear bed base 12, and one end of the frame is located in the U-shaped through groove and the bottom end of the frame is spaced from the bottom end of the U-shaped through groove.

[0049] Refer to Figure 5 , an automatic commutation component 7 is provided on the front bed base 11, and the automatic commutation component 7 ensures accurate commutation distance.

[0050] Refer to Figure 6 , the automatic commutation component 7 includes a rack 71, a gear 72, a transmission shaft 73 and an encoder 74. The rack 71 is fixed on the workbench 3, the gear 72 is meshed with the rack 71 and the gear 72 is sleeved on one end of the transmission shaft 73, the other end of the transmission shaft 73 is connected to the encoder 74, and the transmission shaft 73 is fixed on the front bed base 11.

[0051] In this embodiment, rack seats 75 are respectively provided at both ends of the rack 71, and the rack seats 75 are respectively connected to the workbench 3. The automatic commutation component 7 further includes proximity switches 76 symmetrically arranged on both sides of the gear 72. The proximity switches 76 are arranged on a stop block 77. The stop block 77 is L-shaped and one end of the stop block 77 is connected to the proximity switch 76, and the other end is used to limit the moving distance of the rack seat 75

[0052] Specifically, the gear 72 is connected to the transmission shaft 73 through a coupling. The rack 71 moves with the workbench 3, thereby driving the gear 72 to rotate. Through the transmission shaft 73 and the drive of the coupling, the encoder 74 rotates and emits rotation pulses; the control system receives the pulses, takes the center position as the standard, and calculates the running distance of the rack 71 through counting; the control system pre-sets the running distance. When the workbench 3 moves to the set distance (pulses), the control system issues a commutation signal to drive the control system to commutate; when the encoder 74 fails or the system fails and causes the counting system to fail, after the moving part overtravels, the rack seat 75 runs above the proximity switch 76, and the proximity switch 76 senses and issues a forced commutation or stop signal; when manually moving in a certain direction, the control system displays the distance but does not compare it with the set distance. When the workbench 3 reaches the limit position and senses the signal sent by the proximity switch 76, an overtravel fault alarm is issued. At the same time, the side of the rack seat 75 will contact the side of the stop block 77 to forcibly block the workbench 3 and stop the workbench 3. When manually moving in the other direction, the overtravel alarm is cancelled. When switching back to the automatic state, the set position is compared, and the workbench 3 automatically returns to the moving range.

[0053] In this embodiment, a machine case outer cover 2 is provided on the front bed base 11, and sliding doors are symmetrically provided on the machine case outer cover 2. Such a setting can prevent splashing during operation. A glass window is provided on the sliding door, and the internal working conditions can be observed through the glass window, further ensuring the safety of employees.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
