Description

Technical Field

[0001] The present invention relates to the technical field of double-section robotic arms, and in particular to an auxiliary installation jig for adjusting the installation accuracy of a double-section robotic arm. Background Art

[0002] At present, industrial robots are constantly seeking innovation and innovation, and industrial robots with double-section robotic arms have also been widely used. Figure 1 As shown, the double-section robotic arm mainly includes an upper structural beam 100, a lower structural beam 101, a slide rail 102 and a pair of sliders 103 (the sliders 103 include a first slider located at the end and a second slider located in the middle) arranged at intervals on the slide rail 102; the slide rail 102 is installed and fixed on the top surface of the lower structural beam 101, and the slider 103 is installed and fixed on the bottom surface of the upper structural beam 100. The slider 103 is installed in conjunction with the slide rail 102, so that the upper structural beam 100 can slide on the lower structural beam 101.

[0003] At present, when installing a double-section robotic arm, the installation and coordination of the upper structural beam 100, the lower structural beam 101, the slide rail 102 and the slider 103 are all installed based on experience and visual inspection. However, in actual production, since some dimensions of the structural beams have certain deviations after processing, and the through-holes of the linear rails are larger than the diameter of the fastening screws, there is a certain gap between the screw holes. It is difficult for manual workers to accurately position them during installation, resulting in the following defects of the installed double-section robotic arm:

[0004] 1) In the vertical direction, the installation positions of the upper structural beam 100 and the lower structural beam 101 are not aligned;

[0005] 2) In the horizontal direction, there is a large error in the overall parallelism between the upper structural beam 100 and the lower structural beam 101 .

[0006] The above defects directly reduce the overall accuracy of the robotic arm and affect the quality. Summary of the Invention

[0007] In view of the deficiencies in the prior art, the present invention provides an auxiliary installation jig for adjusting the installation accuracy of a double-section robotic arm, so as to overcome the deficiencies in the prior art.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] An auxiliary installation jig for adjusting the installation accuracy of a double-section robotic arm includes a base plate and a first positioning plate and a second positioning plate standing upright on the base plate, further comprising:

[0010] The first positioning plate and the second positioning plate are both Z-shaped plates. The first positioning plate, the second positioning plate and the bottom plate are combined to form a symmetrical step-shaped positioning groove, which includes an upper positioning groove with a larger width and a lower positioning groove with a smaller width; a support assembly is respectively provided at the four corners of the bottom of the upper positioning groove;

[0011] A slider debugging window is provided in the middle of each of the first positioning plate and the second positioning plate;

[0012] The side wall of the step-shaped positioning groove is further provided with a slider limiting assembly, which is inserted into the step-shaped positioning groove from the side and limits the first slider and the second slider on the double-section mechanical arm.

[0013] Furthermore, the slider limiting assembly includes a support frame, a limiting half frame and a manual screw; the support frame is fixed to the outside of the second positioning plate, the limiting half frame is integrally connected to the manual screw, the manual screw is threadedly installed in the ear on the support frame, and the support frame supports the limiting half frame and the manual screw.

[0014] Furthermore, the top surface of the base plate is provided with a first assembly groove and a second assembly groove along the length direction; the first positioning plate is vertically movably mounted on the base plate along the edge of the first assembly groove, and the second positioning plate is vertically fixedly mounted on the base plate along the edge of the second assembly groove.

[0015] Furthermore, a first guide groove is provided on the top surface of the bottom plate along the width direction, and the first guide groove cooperates with a first guide block provided at the bottom of the first positioning plate.

[0016] Furthermore, the support assembly includes an upper support block and a lower support seat arranged up and down, and a second guide block is provided on the bottom surface of the upper support block to cooperate with a second guide groove provided on the top surface of the lower support seat.

[0017] Preferably, locking pins are provided at both ends of the first positioning plate, and the locking pins cooperate with locking holes provided on the bottom plate.

[0018] Preferably, the first guide groove is a dovetail groove, and the first guide block is a dovetail slider.

[0019] Preferably, the second guide groove is a dovetail groove, and the second guide block is a dovetail slider.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1) In this case, an auxiliary installation fixture for adjusting the installation accuracy of a double-section robotic arm is provided. A symmetrical step-shaped positioning groove is formed by combining a first positioning plate, a second positioning plate, and a bottom plate to ensure that the upper structural beam in the upper positioning groove and the lower structural beam in the lower positioning groove are always aligned.

[0022] 2) In this case, an auxiliary installation fixture for adjusting the installation accuracy of a double-section robotic arm is provided, wherein support components are respectively provided at the four corners of the bottom of the upper positioning groove, and detachable upper support blocks are connected to and supported at the four corners of the bottom surface of the upper structural beam, thereby ensuring the horizontality of the upper structural beam in the upper positioning groove during the assembly process of the double-section robotic arm.

[0023] 3) In the support assembly, since the upper support block is detachable, in actual use, it is only necessary to uniformly replace the upper support blocks of different heights to adapt to supporting upper structural beams of different models, and also to adapt to slide rails or sliders of different heights, thereby enhancing adaptability.

[0024] 4) Slider debugging windows are opened in the middle of the first positioning plate and the second positioning plate, which is more conducive to the installation and alignment of the two sliders and the upper structural beam.

[0025] 5) This case is an installation auxiliary fixture for adjusting the installation accuracy of a double-section robotic arm. The installation distance between the front and rear sliders is limited by a slider limit assembly, thereby ensuring that the two sliders are accurately aligned with the upper structural beam, the installation holes are more accurate, and the installation work is more efficient.

[0026] 6) The first positioning plate is movable and the second positioning plate is fixed, so that the width of the stepped positioning groove can be adjusted in multiple levels. The width of the stepped positioning groove can be adjusted by simply loosening or tightening the locking pin. At the same time, double-section robotic arms of different models and widths can be installed and debugged in the stepped positioning groove, which is more applicable.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a connection between the internal parts of two components; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Please also see Figure 1-7 The present invention provides an installation auxiliary fixture for adjusting the installation accuracy of a double-section robotic arm, comprising: a base plate 1, and a first positioning plate 2 and a second positioning plate 3 standing upright on the base plate 1.

[0041] The base plate 1 has a first assembly groove 11 and a second assembly groove 12 on both sides of its top surface along the length direction; the first positioning plate 2 is vertically movably installed on the base plate 1 along the edge of the first assembly groove 11, and the second positioning plate 3 is vertically fixedly installed on the base plate 1 along the edge of the second assembly groove 12, and the first positioning plate 2 and the second positioning plate 3 are vertically opposite to each other.

[0042] A first guide groove 13 is also provided on the top surface of the base plate 1 along the width direction. The first guide groove 13 cooperates with a first guide block 14 provided at the bottom of the first positioning plate 2, so that the first positioning plate 2 can slide laterally on the base plate 1, and the distance between the first positioning plate 2 and the second positioning plate 3 is adjustable. At the same time, double-section robotic arms of different models and widths can be installed and debugged within the distance between the first positioning plate 2 and the second positioning plate 3, which has stronger applicability.

[0043] Furthermore, locking pins 15 are provided at both ends of the first positioning plate 2. The locking pins 15 cooperate with the locking holes 16 opened on the base plate 1 to lock the first positioning plate 2 on the base plate 1. The distance between the first positioning plate 2 and the second positioning plate 3 can be adjusted by simply loosening the locking pins 15.

[0044] The first positioning plate 2 and the second positioning plate 3 are both Z-shaped plates, and the first positioning plate 2 and the second positioning plate 3 are relatively upright on the base plate 1, so that the first positioning plate 2, the second positioning plate 3 and the base plate 1 are combined to form a symmetrical step-shaped positioning groove 4. The step-shaped positioning groove 4 includes an upper positioning groove 41 with a large width and a lower positioning groove 42 with a small width. The upper positioning groove 41 is used to position the upper structural beam 100, and the lower positioning groove 42 is used to position the lower structural beam 101. Since the step-shaped positioning groove 4 is symmetrical, the upper structural beam 100 in the upper positioning groove 41 and the lower structural beam 101 in the lower positioning groove 42 are always kept in a centered state.

[0045] Furthermore, in order to enhance the compatibility between the stepped positioning groove 4 and different types of double-section robotic arms, a support assembly with the same structure is respectively provided at the four corners of the bottom of the upper positioning groove 41 .

[0046] The support assembly 5 includes an upper support block 51 and a lower support seat 52 arranged in an upper and lower position. The bottom surface of the upper support block 51 is provided with a second guide block that cooperates with the second guide groove provided on the top surface of the lower support seat 52, so that the upper support block 51 is detachable. The four lower support seats 52 are respectively fixed on the first positioning plate 2 and the second positioning plate 3. The four upper support blocks 51 are respectively connected to and supported at the four corners of the bottom surface of the upper structural beam 100, thereby ensuring the horizontality of the upper structural beam 100 in the upper positioning groove 41 during the assembly process of the double-section robotic arm. Since the upper support block 51 is detachable, in actual use, it is only necessary to uniformly replace the upper support blocks 51 of different heights to adapt to support upper structural beams 100 of different models and also adapt to slide rails 102 or sliders 103 of different heights, thereby enhancing adaptability.

[0047] Furthermore, a slider debugging window 6 is provided in the middle of each of the first positioning plate 2 and the second positioning plate 3, so that the side wall of the step-shaped positioning groove 4 has a notch, and the installation position of the second slider can be observed from the side through the slider debugging window 6 (the second slider is located in the middle of the step-shaped positioning groove 4. If the slider debugging window 6 is not provided, the second slider cannot be seen from the front, back, left, right, up and down directions), which is more conducive to the installation alignment of the two sliders 103 and the upper structural beam 100 (fixing hole alignment).

[0048] Furthermore, the side wall of the step-shaped positioning groove 4 is also provided with a slider limiting assembly 7, which is inserted into the step-shaped positioning groove 4 from the side and is clamped between the first slider and the second slider, thereby limiting the distance between the first slider and the second slider, ensuring that the two sliders 103 are accurately aligned with the upper structural beam 100.

[0049] Preferably, in this embodiment, the slider limit assembly 7 includes a support frame 71, a limit half frame 72 and a manual screw 73; the support frame 71 is fixed to the outside of the second positioning plate 3, the limit half frame 72 is integrally connected to the manual screw 73, the manual screw 73 is screwed into the ear on the support frame 71, and the support frame 71 supports the limit half frame 72 and the manual screw 73; by rotating the manual screw 73, the manual screw 73 and the limit half frame 72 move integrally toward the inside of the step-shaped positioning groove 4, so that the limit rods at both ends of the limit half frame 72 are inserted into the gap between the upper structural beam 100 and the lower structural beam 101, and the distance between the two limit rods on the limit half frame 72 is the installation spacing of the first slider and the second slider, thereby ensuring that the two sliders 103 are accurately aligned with the upper structural beam 100, and the installation of the holes is more efficient. At the same time, since the side wall of the stepped positioning groove 4 is provided with a slider debugging window 6, it is more convenient to observe or adjust the position of the second slider from the side, further improving the installation efficiency of the two sliders 103 and the upper structural beam 100.

[0050] Preferably, in this embodiment, the first guide groove 13 and the second guide groove are both dovetail grooves, and the first guide block 14 and the second guide block are both dovetail sliders.

[0051] The usage process of the installation auxiliary fixture in this case in actual working conditions is as follows:

[0052] 1) When assembling the double-section robotic arm, manually place the lower structural beam 101 into the lower positioning groove 42;

[0053] 2) Install and lock the slide rail 102 onto the lower structural beam 101;

[0054] 3) Turn the manual screw 73 to insert the limiting rods at both ends of the limiting half frame 72 in the limiting assembly into the stepped positioning groove 4;

[0055] 4) Adjust the installation distance between the first slider and the second slider so that the limiting rods at both ends of the limiting half frame 72 can position the first slider and the second slider;

[0056] 5) Place the upper structural beam 100 into the upper positioning groove 41 and adjust the model of the upper support block 51 in the support assembly 5 according to the actual height of the upper structural beam 100, the slide rail 102, and the slider 103 so that the upper support block 51 horizontally supports the upper structural beam 100;

[0057] 6) Fasten the upper structural beam 100 and the two sliders 103. Since the two sliders 103 have been limited by the slider limiting assembly 7, the assembly holes on the sliders 103 are accurately aligned with the upper structural beam 100, and the installation is fast and efficient.

[0058] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
