Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control machine tools, and more specifically, relates to a numerical control machine tool for producing half shafts. Background Art

[0002] Axle shafts, also called drive shafts, connect the differential to the drive wheels. They transmit torque between the transmission reducer and the drive wheels. Each half shaft has a universal joint at its inner and outer ends, connected to the reducer gear and the inner ring of the wheel hub bearing via splines on the joint.

[0003] Based on the above, the inventors have found the following problems: the machining heads of current CNC machine tools are mostly fixed inside the machine tools by bolts. When they need to be disassembled, repaired or replaced, corresponding tools must be specially prepared and multiple bolts need to be tightened, which wastes a lot of time and brings inconvenience to the staff. In addition, a large amount of waste chips will be generated when processing the half-shafts, which cannot be collected in a unified manner. The debris accumulates in the machine tool, causing inconvenience to subsequent processing.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a CNC machine tool for producing half-axles is provided in order to achieve a purpose with greater practical value. Utility Model Content

[0005] The purpose and effect of the utility model of a CNC machine tool for producing half shafts are achieved by the following specific technical means:

[0006] A CNC machine tool for producing half-axles includes a machine tool body, a support frame is provided inside the machine tool body, a three-jaw chuck is provided on the top of the support frame, a group of electric telescopic rods are installed on the inner wall of the machine tool body, one side of the electric telescopic rods is connected to a mounting plate, one side of the mounting plate is installed with a connecting plate, one side of the connecting plate is provided with a clamping assembly, the other side of the connecting plate is installed with a fixing block, a motor is provided inside the fixing block, the output shaft of the motor passes through the fixing block to the outside and is connected to a processing head, and a collecting assembly is provided at the bottom of the machine tool body.

[0007] Furthermore, the locking assembly includes several mounting rods arranged on one side of the connecting plate, one side of the mounting rods is connected to a mounting block, several mounting holes are opened on the mounting plate, one side of the mounting holes is connected to a slide groove, and the mounting rods and slide grooves, and the mounting blocks and mounting holes are all matched.

[0008] Furthermore, the diameter of the mounting hole is greater than the width of the sliding groove.

[0009] Furthermore, a chamber is opened inside the mounting plate, a pull rod is provided on one side of the mounting plate, one end of the pull rod passes through the mounting plate to the chamber and is connected to a limit plate, a spring is sleeved on the pull rod, and a clamping block is installed on one side of the limit plate.

[0010] Furthermore, a through hole is provided on the connecting plate, and the through hole matches the card block.

[0011] Furthermore, the collection assembly includes two sets of guide plates, a collection box is provided below the guide plates, and one end of the collection box passes through the machine tool body to the outside where a handle is installed.

[0012] Furthermore, a control panel is installed on one side of the machine tool body, and the control panel is electrically connected to each electrical appliance.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Through the coordinated use of the mounting block, mounting hole, slide groove, pull rod, spring and clamping block, the mounting block is inserted into the mounting hole, and the clamping block is squeezed by the connecting plate and moves to the inner side of the chamber. At this time, the spring is compressed, and then the connecting plate is rotated to rotate the mounting block to the other side of the slide groove. Since the width of the mounting block is greater than the width of the slide groove, the connecting plate is fixed on one side of the mounting plate. When the through hole is rotated to the corresponding position of the clamping block, the spring rebounds and squeezes the clamping block into the through hole to fix the connecting plate, thereby avoiding relative rotation between the mounting plate and the connecting plate, thereby improving the stability and safety of the device. When the processing head needs to be disassembled, the pull rod is pulled to disengage the clamping block from the through hole, and the connecting plate is rotated to pull the mounting block out of the mounting hole. There is no need to prepare corresponding tools to tighten the bolts, which saves time and improves work efficiency.

[0015] 2. Through the coordinated use of the guide plate and the collection box, the waste chips generated during processing fall into the collection box below through the guide plate. When the collection box is full of waste chips, the staff pulls out the collection box by the handle and cleans the waste chips inside in a centralized manner, thus avoiding the problem of waste chips accumulating inside the machine tool and affecting subsequent processing.

[0029] Among them, the locking assembly includes several mounting rods 10 arranged on one side of the connecting plate 6, one side of the mounting rod 10 is connected to a mounting block 11, and several mounting holes 12 are opened on the mounting plate 5, one side of the mounting hole 12 is connected to a slide groove 13, the mounting rod 10 and the slide groove 13, the mounting block 11 and the mounting hole 12 are all matched, through the coordinated use of the mounting block 11, the mounting hole 12, the slide groove 13 and the mounting plate 5, the mounting block 11 is inserted from the mounting hole 12, and then the connecting plate 6 is rotated to rotate the mounting block 11 to the other side of the slide groove 13. Since the width of the mounting block 11 is greater than the width of the slide groove 13, the connecting plate 6 is fixed to one side of the mounting plate 5, which is easy to install and brings convenience to the staff.

[0030] The diameter of the mounting hole 12 is greater than the width of the sliding groove 13 .

[0031] Among them, the interior of the mounting plate 5 is provided with a chamber 14, and a pull rod 15 is provided on one side of the mounting plate 5. One end of the pull rod 15 passes through the mounting plate 5 to connect to the limit plate 16 in the chamber 14. A spring 17 is sleeved on the pull rod 15, and a clamping block 18 is installed on one side of the limit plate 16. Through the coordinated use of the pull rod 15, the spring 17 and the clamping block 18, when the processing head 9 is installed, the mounting block 11 is inserted into the mounting hole 12, and the clamping block 18 is squeezed by the connecting plate 6 and moves to the inside of the chamber 14. When the spring 17 is compressed, when the through hole 19 is rotated to the corresponding position of the block 18, the spring 17 rebounds and squeezes the block 18 into the through hole 19, fixing the connecting plate 6, avoiding relative rotation between the mounting plate 5 and the connecting plate 6, and improving the stability and safety of the device. When the processing head 9 needs to be disassembled, pull the pull rod 15 to disengage the block 18 from the through hole 19, and rotate the connecting plate 6 to pull the mounting block 11 out of the mounting hole 12.

Through the coordinated use of the guide plate 20 and the collection box 21, the waste chips generated during processing fall into the collection box 21 below through the guide plate 20. After the collection box 21 is full of waste chips, the staff pulls out the collection box 21 through the handle 22 and cleans the waste chips inside in a centralized manner, thereby avoiding the problem of waste chips accumulating inside the machine tool and affecting subsequent processing.

[0034] A control panel 23 is installed on one side of the machine tool body 1 , and the control panel 23 is electrically connected to various electrical appliances.

Since the width of the mounting block 11 is greater than the width of the slide groove 13, the connecting plate 6 is fixed to one side of the mounting plate 5. When the through hole 19 is rotated to the corresponding position of the block 18, the spring 17 rebounds and squeezes the block 18 into the through hole 19, fixing the connecting plate 6 and avoiding the mounting plate 5 and the connecting plate 6. Relative rotation occurs, which improves the stability and safety of the device. When the processing head 9 needs to be disassembled, the pull rod 15 is pulled to disengage the clamping block 18 from the through hole 19, and the connecting plate 6 is rotated to pull the mounting block 11 out of the mounting hole 12.
