Description

Technical Field

[0001] The utility model relates to the technical field of machine tool slides, in particular to an angle-adjustable cross slide structure for machine tools. Background Art

[0002] A cross slide refers to a combined slide formed by combining two sets of linear slides in the X-axis and Y-axis directions. One set of linear slides is fixed to the slider of the other set of slides, so that the slider can complete fixed-point motion, linear or curved motion on the plane coordinate. It is mainly used in the automation industry. An existing patent (Announcement No.: CN213318829U) discloses a combined machine tool cross slide. This new type of use proposes to adjust the angle between the mounting seat and the base by flipping it up and down. However, in actual application, according to the above technical solution, the mounting seat and the base are hinged at one end, and the electric push rod at the other end is fixedly connected to the mounting seat and the base at the upper and lower ends respectively. This makes it impossible for the electric push rod to extend and retract while maintaining its original direction, and thus cannot achieve the purpose of adjusting the angle between the mounting seat and the base. To this end, we propose an angle-adjustable machine tool cross slide structure. Utility Model Content

[0006] In the above solution, an assembly seat is fixed on the top of the second sliding seat, and the assembly seat is sleeved on the middle part of the support platform.

[0007] In the above scheme, a sinking base is provided at one end of the support platform, and a lifting frame is installed at one end of the mounting platform three close to the sinking base. Connecting seats are provided inside the sinking base and at the bottom of the lifting frame, and both ends of the electric push rod are connected to the connecting seats through pin shafts.

[0008] In the above solution, moving blocks are fixed on the bottom of the first and second clamping plates, and a moving groove matching the moving blocks is provided on the top of the third mounting platform.

[0010] In the above solution, a mounting groove is provided in the mounting platform three, and a driving device connected to the driving shaft is installed in the mounting groove.

[0011] In the above solution, the ends of the first and second clamping plates are covered with buffer pads.

[0012] The advantages and beneficial effects of the present invention are as follows: by arranging the mounting platform three, the support platform, the connecting seat and the electric push rod, on the basis of hinged connection between one end of the mounting platform three and the support platform, the electric push rod is used to connect the mounting platform three and the other end of the support platform, and by extending the electric push rod, the mounting platform three is turned upward, thereby expanding the angle between the mounting platform three and the support platform, and by shortening the electric push rod, the mounting platform three is turned downward, thereby reducing the angle between the mounting platform three and the support platform.

By setting the clamping plate one, clamping plate two, connecting arms, gears, tooth surfaces, drive shafts and drive devices, the ends of clamping plate one and clamping plate two are used to clamp the workpiece to be processed. The power generated by the drive device causes the drive shaft to drive the gear to rotate, thereby moving clamping plate one along the mounting platform three and cooperating with the connecting arm to drive clamping plate two to move. Compared with the existing technology, the drive device can automatically start the gears to move clamping plate one and clamping plate two, thereby completing the task of clamping the workpiece and improving the degree of automation.

DETAILED DESCRIPTION

[0019] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: an angle-adjustable machine tool cross slide structure, comprising a mounting platform 1 and a mounting platform 3, wherein a sliding seat 2 assembled with the mounting platform 3 is slidably connected between the two ends of the mounting platform 1, and a sliding seat 2 4 is slidably connected between the two ends of the mounting platform 3;

[0021] Specifically, a linear reciprocating motion mechanism is provided in both mounting platform 1 and mounting platform 2 3, and the linear reciprocating motion mechanism includes a ball screw rotatably installed between the two ends of mounting platform 1 and mounting platform 2 3, and sliding seat 1 2 and sliding seat 2 4 are respectively threadedly connected to the corresponding ball screws, and guide rods fixed to mounting platform 1 1 and mounting platform 2 3 are provided on both sides of the ball screw, and the guide rods movably pass through sliding seat 1 2 and sliding seat 2 4, and driving motors connected to the ball screws are installed on mounting platform 1 and mounting platform 2 3, and the driving motors are connected to the power supply, thereby constituting the main structure of the cross slide.

[0022] A support platform 6 is provided above the sliding seat 2 4;

[0023] Furthermore, an assembly seat 5 is fixed to the top of the sliding seat 2 4, and the assembly seat 5 is sleeved on the middle of the support platform 6, and the assembly seat 5 is connected to the support platform 6 by fasteners;

[0024] One end of the top of the support platform 6 is hinged with a mounting platform 3 7, and an electric push rod 19 is movably installed between the other end of the mounting platform 3 7 and the support platform 6;

[0025] Furthermore, a sinking base 18 is provided at one end of the support platform 6. The depth of the sinking base 18 is equal to the shortest total length of the electric push rod 19, so that the electric push rod 19 can be completely placed in the sinking base 18 when it is at its shortest, so that the support platform 6 and the mounting platform 3 7 can be overlapped, so that the mounting platform 3 7 is in a horizontal state, thereby improving the flexibility of the mounting platform 3 7. A lifting frame 20 is installed on one end of the mounting platform 3 7 near the sinking base 18 by fasteners. The lifting frame 20 is sleeved on both sides of the mounting platform 3 7. Connecting seats 21 are fixedly provided in the sinking base 18 and at the bottom of the lifting frame 20. Both ends of the electric push rod 19 are connected to the connecting seats 21 by pins. When the angle between the mounting platform 3 7 and the support platform 6 changes, the electric push rod 19 can automatically adjust the angle to adapt to the positional relationship between the mounting platform 3 7 and the support platform 6.

[0026] Specifically, by setting the mounting platform three 7, the support platform 6, the connecting seat 21 and the electric push rod 19, on the basis of the hinge connection between one end of the mounting platform three 7 and the support platform 6, the electric push rod 19 is used to connect the mounting platform three 7 and the other end of the support platform 6. By extending the electric push rod 19, the mounting platform three 7 is flipped upward, thereby expanding the angle between the mounting platform three 7 and the support platform 6. By shortening the electric push rod 19, the mounting platform three 7 is flipped downward, thereby reducing the angle between the mounting platform three 7 and the support platform 6. Compared with the existing technology, in conjunction with the connecting seat 21, the electric push rod 19 can move as the angle between the mounting platform three 7 and the support platform 6 changes, so as to adapt to the positional relationship between the mounting platform three 7 and the support platform 6, so as to improve the flexibility of the mounting platform three 7 and facilitate use.

[0027] Two pairs of oppositely arranged clamping plates 1 8 and 2 10 are slidably provided in the mounting platform 3 7;

[0028] Furthermore, a moving block 12 is fixed to the bottom of each of the first and second clamping plates 8 and 10, and a moving groove 13 is provided on the top of the third mounting platform 7 to match the moving block 12. The moving block 12 and the moving groove 13 cooperate to make the first and second clamping plates 8 and 10 move more smoothly on the third mounting platform 7.

[0029] Furthermore, a gear 14 rotatably mounted on the mounting platform 3 7 via a drive shaft 15 is provided between the first and second clamping plates 8 and 10. A tooth surface 9 meshing with the gear 14 is provided on one side of the first clamping plate 8, and a connecting arm 11 is fixed between the first and second clamping plates 8 and 10. The connecting arm 11 connects the first and second clamping plates 8 and 10. By rotating the drive shaft 15, the gear 14 rotates, driving the first clamping plate 8 to move, thereby causing the first and second clamping plates 8 and 10 to move simultaneously, so as to clamp workpieces of different widths.

[0030] Furthermore, a mounting groove 16 is provided in the mounting table 3 7, and a driving device 17 connected to the drive shaft 15 is installed in the mounting groove 16. The driving device 17 includes a motor, and the motor is connected to a reducer. The rotating shaft of the reducer is connected to the drive shaft 15, and then transmits power to the drive shaft 15, so that the gear 14 rotates, thereby achieving the purpose of automatically starting the clamping operation. In actual application, before the workpiece enters the present invention through the manipulator, the specific size of the workpiece is measured, and the motor is a stepping motor, so as to further control the rotation angle of the drive shaft 15, thereby controlling the moving distance of the splint 1 8 and the splint 2 10;

[0031] Specifically, in actual applications, a driving device 17 can be set at both ends of the mounting platform 3 7 to drive the two pairs of splints 1 8 and 10, or only one driving device 17 can be installed, and then the splints 1 8 and 10 at the other end can be driven through a pulley and belt assembly.

[0032] Furthermore, the ends of the first clamping plate 8 and the second clamping plate 10 are covered with a buffer pad 22; the buffer pad 22 is used to prevent the first clamping plate 8 and the second clamping plate 10 from directly contacting the workpiece surface, thereby preventing the workpiece from being damaged during clamping;

[0033] Specifically, by setting up clamp plate 1 8, clamp plate 2 10, connecting arm 11, gear 14, tooth surface 9, drive shaft 15 and drive device 17, the ends of clamp plate 1 8 and clamp plate 2 10 are used to clamp the workpiece to be processed. The power generated by the drive device 17 causes the drive shaft 15 to drive the gear 14 to rotate, and then clamp plate 1 8 moves along the mounting table 3 7, and cooperates with the connecting arm 11 to drive clamp plate 2 10 to move. Compared with the existing technology, the drive device 17 can automatically start the gear 14 to move clamp plate 1 8 and clamp plate 2 10, thereby completing the task of clamping the workpiece and improving the degree of automation.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
