Technical Field

[0001] The utility model relates to the technical field of numerical control lathes, and more specifically, to a manipulator for a numerical control lathe. Background Art

[0002] Numerical control lathes are one of the most widely used numerical control machine tools at present. They are mainly used for the cutting processing of the inner and outer cylindrical surfaces of shaft parts or disc parts, the inner and outer conical surfaces with any cone angle, the complex revolving inner and outer curved surfaces, and cylindrical and conical threads, etc., and can perform grooving, drilling, reaming, boring and other operations.

[0003] The manipulator for a numerical control lathe is an automated mechanical device.

Detailed implementation manners

[0031] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0032] As Figures 1-6 shown, a numerically controlled lathe manipulator includes: a support 1 fixed on the support 1, a vertical frame 2 fixed on the top of the vertical frame 2, a horizontal frame 3 fixed on the vertical frame 2, a horizontal transmission assembly 4 installed on the horizontal frame 3, a horizontal control box 5 installed on the horizontal transmission assembly 4, a lifting box 6 connected to the horizontal control box 5, a lifting assembly 7 installed in the lifting box 6, a manipulator body 8 installed at the bottom of the lifting assembly 7, a side frame 9 fixed on the side of the vertical frame 2, a synchronous translation assembly 10 installed on the side frame 9, a placement plate 11 installed on the synchronous translation assembly 10, two material placement trays 12 arranged on the placement plate 11, and a positioning assembly 13 arranged on the placement plate 11 and the two material placement trays 12, wherein

[0033] the horizontal transmission assembly 4 cooperates with the lifting assembly 7 to be adapted to control the stable movement of the manipulator body 8 in the horizontal and vertical directions;

[0034] the synchronous translation assembly 10 is adapted to control the movement of the material placement tray 12 synchronously with the picking and placing of materials by the manipulator body 8;

[0035] The positioning component 13 is adapted to stably place the two material placement trays 12 on the placement plate 11. Before the operation of the equipment, the staff places the two material placement trays 12 loaded with parts to be processed on the placement plate 11. Through the set positioning component 13, the accurate and stable placement position of the material placement trays 12 on the placement plate 11 can be ensured, so that when the placement plate 11 moves horizontally, the two material placement trays 12 will not shift in position, thus effectively ensuring the accuracy of the manipulator body 8 to pick and place parts in the material placement trays 12. During use, the synchronous translation component 10 can control the horizontal control box 5 and the lifting box 6 to move stably in the horizontal direction, so that the manipulator body 8 can reciprocate stably between the numerical control machine tool and the two material placement trays 12. The lifting component 7 in the horizontal control box 5 can drive the manipulator body 8 to move stably in the vertical direction, so that when the manipulator body 8 moves between the numerical control machine tool and the two material placement trays 12, it can pick and place the parts placed in the material placement trays 12, and pick and place the parts at the machining position of the numerical control machine tool to complete the transfer before and after part processing. After the manipulator body 8 grasps a single part to be processed in one of the material placement trays 12 and places the processed part on this material placement tray 12, the set synchronous translation component 10 works to control the placement plate 11 to perform a certain small-range horizontal displacement, so that the position of the manipulator body 8 to pick and place parts next time is changed, effectively increasing the range of the manipulator body 8 to pick and place parts, with high practicability and improved work efficiency. After the manipulator body 8 completes the picking and placing of parts on one material placement tray 12 and all the parts on this material placement tray 12 are processed, at this time, with the cooperation of the synchronous translation component 10, a certain large-range horizontal displacement can be performed on the control board, so that when the manipulator body 8 picks and places parts next time, it can pick and place the parts on the other material placement tray 12. While the manipulator body 8 picks and places parts, the staff can replace the material placement tray 12 loaded with the processed parts, so that the manipulator body 8 can continuously pick and place parts, and when the material placement tray 12 is replaced, the manipulator will not encounter the situation of having no parts to pick and place, preventing the numerical control lathe from stopping part processing, ensuring the processing efficiency of the parts. When the material placement tray 12 is replaced, the set protective cover 39 can effectively protect the staff and avoid potential safety hazards.

[0036] Optionally, the synchronous translation component 10 includes a control box 14 fixed to the side frame 9, two transmission gears 15 symmetrically and rotatably installed in the control box 14, a transmission belt 16 meshed and sleeved on the two transmission gears 15, a first motor 17 fixedly installed at the bottom of the control box 14, a sliding groove 18 opened at the top of the control box 14, a clamping plate 19 with one end fixed to the bottom of the placement plate 11 and the other end passing through the sliding groove 18 and fixedly connected to the transmission belt 16, several connecting blocks 20 with one end fixed to the bottom of the placement plate 11 and the other end extending into the control box 14, two first sliding rails 21 symmetrically fixed in the control box and arranged on both sides of the transmission belt 16, and several first sliding blocks 22 movably installed on the two first sliding rails 21 and respectively fixedly connected to the other ends of the several connecting blocks 20;

[0037] The output end of the first motor 17 is fixedly connected to one of the transmission gears 15. After the manipulator body 8 picks up or places one of the parts in the two material placement trays 12, the first motor 17 operates to drive one of the transmission gears 15 to rotate. Then, with the cooperation of the transmission belt 16, the other transmission gear 15 is meshed and driven to rotate synchronously, so that the clamping block moves in the sliding groove 18 and drives the placement plate 11 to move horizontally on the top of the control box 14, so that the manipulator body 8 moves relative to the two material placement trays 12 to the position where the parts to be picked up and stored are located, facilitating the manipulator to pick up the parts at different positions, saving time and effort, and improving work efficiency. When the placement plate 11 is controlled to move, several first sliding blocks 22 connected to the placement plate 11 through several connecting blocks 20 move on the several first sliding rails 21 to guide and limit the movement of the placement plate 11, effectively improving the stability of the placement plate 11 moving on the control box 14.

[0038] Optionally, the positioning component 13 includes several positioning rods 23 fixedly installed on the upper surface of the placement plate 11 and several positioning grooves 24 arranged on the two material placement trays 12;

[0039] Several of the positioning rods 23 are respectively inserted into the several positioning grooves 24 in a fitting manner. When the two material placement trays 12 are placed on the placement plate 11, the several positioning grooves 24 on the two material placement trays 12 respectively correspond to the several positioning rods 23 one by one. Then, under the control and limitation of the several positioning rods 23, the two material placement trays 12 can be ensured to be stable when placed on the placement plate 11, and when the synchronous translation component 10 controls the placement plate 11 to move horizontally, the two material trays will not shift in position, thereby effectively improving the accuracy of the manipulator body 8 in picking up and placing the parts in the two material placement trays 12.

[0040] Optionally, the horizontal transmission assembly 4 includes a lateral transmission rod 25 fixed to the top of the cross frame 3, a first driving rack 26 fixed to the top of the lateral transmission rod 25, two second slide rails 27 fixed to the front surface of the upper lateral transmission rod 25, several second sliding blocks 28 fixed to the upper part of the lifting box 6 and slidably mounted on the two second slide rails 27 respectively, a second motor 29 fixed to the horizontal control box 5, and a first driving gear 30 fixed to the output end of the second motor 29 and meshed with the first driving rack 26. When the lifting assembly 7 drives the manipulator body 8 to complete the picking and placing of the parts to be processed and the processed parts, the second motor 29 is started to drive the first driving gear 30 to rotate. Since the first driving rack 26 is fixed to the lateral transmission rod 25, and the lifting box 6 is slidably engaged with the lateral transmission rod 25 under the cooperation of the two second slide rails 27 and several second sliding blocks 28, the horizontal control box 5 and the lifting box 6 can be controlled to move along the direction of the first driving rack 26 when the first driving gear 30 rotates, so that the parts clamped by the manipulator body 8 can have stable movement in the horizontal direction.

[0041] Optionally, the lifting assembly 7 includes two control blocks 31 symmetrically fixed in the lifting box 6, several third sliding blocks 32 fixed in the lifting box 6 and on the two control blocks 31, two third slide rails 33 slidably mounted with the several third sliding blocks 32, a vertical transmission rod 34 fixedly connected to the two third slide rails 33, a second driving rack 35 fixed to the vertical transmission rod 34, a third motor 36 fixed in the horizontal control box 5, and a second driving gear 37 fixed to the output end of the third motor 36 and meshed with the second driving rack 35;

[0042] The manipulator body 8 is fixed to the bottom of the vertical transmission rod 34. After the lifting box 6 and the horizontal control box 5 are controlled by the horizontal transmission assembly 4 to move to the required positions, the third motor 36 is started to drive the second driving gear 37 to rotate, and then the second driving rack 35 is engaged and driven, so as to control the vertical transmission rod 34 to move synchronously. Under the restriction of the several third sliding blocks 32, the vertical transmission rod 34 fixed with the two third slide rails 33 can be guided, so as to drive the manipulator body 8 to stably move in the vertical direction and complete the picking and placing of the parts to be processed and the processed parts.

[0043] Optionally, several L-shaped connecting rods 38 are symmetrically and fixedly connected to the lower surface of the control box, and a protective cover 39 is fixedly sleeved on the several L-shaped connecting rods 38. Through the arranged protective cover 39, the upper periphery of the control box is protected, and a space for the manipulator body 8 to move is left. Thus, when the staff replaces the two material placing trays 12, potential safety hazards can be avoided when the manipulator body 8 moves above the two material placing trays 12.

[0044] Optionally, both the first driving rack 26 and the second driving rack 35 are helical racks, and both the first driving gear 30 and the second driving gear 37 are helical gears. The advantages of the cooperation between a helical gear and a helical rack include good meshing performance, stable transmission, low noise, and large contact ratio. The meshing of the first driving rack 26, the second driving rack 35, the first driving gear 30 and the second driving gear 37 adopts a helical gear cooperating with a helical rack, thereby effectively improving the load-bearing capacity of the first driving gear 30 and the second driving gear 37, ensuring the service life of the first driving gear 30 and the second driving gear 37, and having a smaller minimum number of teeth without undercut, making the mechanism more compact.

[0045] 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, the present invention can have various modifications and changes. 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.
