Description

Technical Field

[0001] The utility model relates to the technical field of half - shaft production, in particular to a truss robot. Background Art

[0002] The automotive half - shaft is also called the drive axle. The half - shaft is a solid shaft that transmits torque between the differential and the drive wheel. Its inner end is generally connected to the half - shaft gear through splines, and the outer end is connected to the wheel hub. In the production process of the half - shaft, it needs to go through multiple processing procedures. In order to save production transfer time between different procedures, the processing machines are arranged in the order of procedures, and then a truss robot is placed horizontally above the machines to transfer the half - shaft between the machines, so as to shorten the processing time. However, when the existing robots grab the half - shaft, they mostly grab it through the manipulators on two cantilever beams, which makes the overall structure control cumbersome and inconvenient to use. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a truss robot to solve the above problems.

[0004] The utility model realizes the above - mentioned purpose through the following technical solutions:

A moving mechanism for controlling the moving position of the half - shaft workpiece is arranged on the support mechanism, and a grasping mechanism for grasping and clamping the half - shaft is further arranged at the lower end of the moving mechanism. The grasping mechanism includes a mounting frame fixed at the lower end of the moving mechanism. Two left - right lead screws are arranged in parallel on the mounting frame. One end of each left - right lead screw passes through the mounting frame and is equipped with a transmission part. The other end of one of the left - right lead screws is connected to a power source. Two clamping components are arranged on the left - right lead screws. The clamping component includes an adjustment seat arranged on the left - right lead screw. A cylinder is vertically fixed on the adjustment seat. The lower end of the movable rod of the cylinder is provided with a movable seat. Two V - shaped clamping rods are arranged at the lower end of the movable seat. A connecting rod connected to the adjustment seat is arranged on the V - shaped clamping rod. Fixed plates are arranged on the opposite bent surfaces of the V - shaped clamping rod.

[0006] Further setting: The left - right lead screws are rotationally connected to the mounting frame, and the adjustment seat is threadedly connected to the left - right lead screws.

[0005]

[0007] Further setting: A sliding groove through which the cylinder passes is opened on the mounting frame.

[0009] Further setting: A rubber cushion plate is installed on the fixed plate through bolts, and the clamping surface of the rubber cushion plate is set to be patterned.

[0010] Further settings: The support mechanism includes vertical columns arranged at intervals, and a cross beam is fixed at the upper end of the columns. The cross beam is a horizontal double-beam structure.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] Through the arrangement of the grasping mechanism at the lower end of the moving mechanism, the left and right lead screws rotate to drive the adjustment seats to move relative to each other, so that the distance between the adjustment seats meets the transfer requirements of half shafts of different lengths, improving the versatility of the overall use. Through the extension or contraction of the cylinder, the movable seat is driven to move downward or upward, so that the movable seat pushes the V-shaped clamping rod to open outward or rotate and close to the middle under the support of the connecting rod, loosening or clamping and limiting the half shaft, improving the convenience of transferring and moving the half shaft.

[0023] The present utility model will be further described below with reference to the drawings:

[0024] As Figures 1 - 5 shown, a truss robot includes a support mechanism spanning across the upper side of a processing machine table. A moving mechanism for controlling the moving position of a half shaft workpiece is provided on the support mechanism, and a grasping mechanism for grasping and clamping the half shaft is further included at the lower end of the moving mechanism;

[0025] In this embodiment: The support mechanism includes columns 11 arranged vertically at intervals. A cross beam 12 is fixed to the upper end of the columns 11. The cross beam 12 is a horizontally arranged double beam structure, which is used to improve the overall support stability.

[0026] In this embodiment: The moving mechanism includes a transverse moving component 21 arranged on the cross beam 12. A longitudinal moving component 22 is arranged on the transverse moving component 21, and a vertical moving component 23 is arranged on the longitudinal moving component 22. The transverse moving component 21, the longitudinal moving component 22, and the vertical moving component 23 are all electric sliding members installed on sliding rails, which are used for adjusting the movement in the transverse, longitudinal, and vertical directions. This part of the content is prior art and is known to those skilled in the art, so it will not be elaborated here.

[0027] In this embodiment: The grasping mechanism includes a mounting frame 31 fixed to the lower end of the moving mechanism. There are two left - right lead screws 32 arranged in parallel on the mounting frame 31. One end of each left - right lead screw 32 passes through the mounting frame 31 and is equipped with a transmission part 34. The other end of one of the left - right lead screws 32 is connected to a reduction motor 33. There are two clamping assemblies arranged on the left - right lead screws 32. The clamping assembly includes an adjustment seat 35 arranged on the left - right lead screw 32. A cylinder 36 is vertically fixed on the adjustment seat 35. A sliding groove through which the cylinder 36 passes is opened on the mounting frame 31. The lower end of the movable rod of the cylinder 36 is provided with a movable seat 37. Two V - shaped clamping rods 38 are arranged at the lower end of the movable seat 37. A connecting rod 310 connected to the adjustment seat 35 is arranged on the V - shaped clamping rod 38. Fixed plates 39 are arranged on the opposite bent surfaces of the V - shaped clamping rod 38. The left - right lead screws 32 are rotatably connected to the mounting frame 31, and the adjustment seat 35 is threadedly connected to the left - right lead screws 32. The transmission part 34 is a synchronous pulley, and a synchronous belt is sleeved between the transmission parts 34. By driving one of the left - right lead screws 32 to rotate through the reduction motor 33, and through the power transmission of the transmission part 34, the two left - right lead screws 32 rotate synchronously. The left - right lead screws 32 drive the adjustment seats 35 to move relatively, so that the distance between the adjustment seats 35 meets the requirements of the half - shaft length, facilitating the adjustment and use for half - shafts of different length specifications. The movable seat 37 and the V - shaped clamping rod 38 are rotatably connected by a pin shaft, and both ends of the connecting rod 310 are rotatably connected to the adjustment seat 35 and the V - shaped clamping rod 38 by pin shafts. By extending the cylinder 36, the movable seat 37 is pushed downward, and the movable seat 37 spreads the V - shaped clamping rod 38 outward. After the V - shaped clamping rod 38 is aligned with the half - shaft, the cylinder 36 contracts, driving the movable seat 37 to move upward. The V - shaped clamping rod 38 rotates and closes in the middle under the support of the connecting rod 310, so that the rubber cushion plate 311 clamps and limits the half - shaft. The rubber cushion plate 311 is installed on the fixed plate 39 by bolts, and the clamping surface of the rubber cushion plate 311 is set to be patterned, improving the reliability of clamping and fixing the half - shaft.

[0028] The working principle and usage process of the present utility model: During the processing of the half - shaft, according to the length specification of the half - shaft, by driving one of the left - right lead screws 32 to rotate through the reduction motor 33, and through the power transmission of the transmission part 34, the two left - right lead screws 32 rotate synchronously. The left - right lead screws 32 drive the adjustment seats 35 to move relatively, so that the distance between the adjustment seats 35 meets the requirements of the half - shaft length. Then, the overall position of the grasping mechanism is adjusted through the lateral movement component 21, the longitudinal movement component 22, and the vertical movement component 23, so that the grasping component is corresponding to the upper side of the half - shaft. By extending the cylinder 36, the movable seat 37 is pushed downward, and the movable seat 37 spreads the V - shaped clamping rod 38 outward. After the V - shaped clamping rod 38 is aligned with the half - shaft, the cylinder 36 contracts, driving the movable seat 37 to move upward. The V - shaped clamping rod 38 rotates and closes in the middle under the support of the connecting rod 310, so that the rubber cushion plate 311 clamps and limits the half - shaft, and then it moves to the next processing step.
