Description

Technical Field

[0001] The utility model relates to the technical field of casting grinding, in particular to a saddle casting clamping tool for a grinding robot. Background Art

[0002] The saddle casting on a machine tool generally refers to one of the main structural components of the machine tool, which is used to support and position the worktable (or beam) and its load. Saddle castings are usually made of cast iron or cast steel, with high strength and rigidity to ensure the stability and accuracy of the machine tool during processing. These castings often require precise processing and assembly to ensure the operating accuracy and long-term stability of the machine tool. The castings are relatively rough after the initial production, and generally need to be cleaned and polished. Robot polishing has become one of the main polishing methods now because of its high precision and consistency. During the polishing process, a central fixture is needed to fix the casting to prevent the casting from shaking during the polishing process.

[0003] Most existing casting fixtures are customized according to the size of the castings, and their sizes are fixed. When castings of different sizes need to be clamped, the corresponding fixtures need to be replaced, which results in high cost.

[0004] Therefore, we proposed a saddle casting clamping tool for a grinding robot to solve the above-mentioned problems. Utility Model Content

[0028] See also Figure 1-4As shown, the utility model provides a saddle casting clamping tool for a grinding robot, including a base plate 1 and a movable clamping device 2, a first positioning support mechanism 3, a second support mechanism 4 and a limiting mechanism 5 installed on the base plate 1, the movable clamping device 2 is located in the middle of one side of the base plate 1, two first positioning support mechanisms 3 are provided, and are respectively located on both sides of the movable clamping device 2, the second support mechanism 4 and the limiting mechanism 5 are located on the opposite side of the movable clamping device 2, the second support mechanism 4 and the first positioning support mechanism 3 have the same structure, and are distributed in a triangular shape with the two first positioning support mechanisms 3, two limiting mechanisms 5 are provided, and are respectively located on both sides of the second support mechanism 4, a plurality of screw holes 6 are opened on the base plate 1 along its length direction, and the two first positioning support mechanisms 3 are screwed into different screw holes 6 by bolts 7 to be fixed to the base plate 1.

[0029] like Figure 2 and Figure 3 The movable clamping device 2 shown includes two bases 21 relatively fixed on the bottom plate 1, and a screw 22 and a movable seat 23 located between the two bases 21. The two ends of the screw 22 are rotatably connected to the side walls of the two bases 21 respectively, and its rear end passes through the rear base 21 and is fixed with a handle 26. The movable seat 23 is threadedly connected to the screw 22. A column 24 is arranged on the top of the movable seat 23, and a clamping rod 25 is arranged on the column 24. A first abutment block 27 with tooth patterns is fixed to the front side of the clamping rod 25.

[0030] During clamping, the saddle casting 9 is placed on the two first positioning support mechanisms 3, and the screw rod 22 is rotated by the turning handle 26 to drive the movable seat 23 to move, so that the first abutment block 27 with the tooth pattern abuts against the rear side of the saddle casting 9. When continuing to move, the movable seat 23 drives the saddle casting 9 to move toward the limiting mechanism 5 until the other side abuts against the limiting mechanism 5, thereby completing the limitation in the width direction.

[0031] like Figure 2 and Figure 3 As shown, the first positioning support mechanism 3 includes a positioning base plate 31 and two vertical plates 32 relatively fixed on the top of the positioning base plate 31, and a rotating wheel 33 is rotatably installed between the two vertical plates 32, and the axial direction of the rotating wheel 33 is perpendicular to the axial direction of the screw 22 to ensure that the rotating wheel 33 is arranged along the width direction of the base plate 1, and a fixed positioning clamp 34 on the side of the vertical plate 32 away from the movable clamping device 2, the top of the positioning clamp 34 extends upward and is higher than the top wall of the vertical plate 32, and a second abutment block 35 is arranged on the side of the positioning clamp 34 close to the vertical plate 32.

[0032] According to the size of the saddle casting 9, the first positioning support mechanism 3 is fixed in different screw holes 6, so that the saddle casting 9 is placed on the rotating wheels 33 in the first positioning support mechanism 3 and the second support mechanism 4, and the two second abutment blocks 35 are respectively pressed against the left and right ends of the saddle casting 9 to limit the length direction of the saddle casting 9. At the same time, due to the setting of the rotating wheel 33, the movable clamping device 2 can drive the saddle casting 9 to slide along the width direction.

[0033] like Figure 2 and Figure 3 As shown, the limiting mechanism 5 includes a limiting base plate 51 fixed on the base plate 1, a limiting column 52 and a supporting column 54 are fixed on the top of the limiting base plate 51, the supporting column 54 is located on the side of the limiting column 52 close to the movable clamping device 2, a third abutting block 53 with tooth patterns is provided on the side of the limiting column 52 close to the supporting column 54, a top column 55 is provided on the top of the support column 54, and the top of the limiting column 52 is higher than the top of the top column 55.

[0034] When the movable clamping device 2 drives the saddle casting 9 to slide in the width direction, when the side wall of the saddle casting 9 abuts the third abutment block 53, the movable clamping device 2 can be used to limit the width direction of the saddle casting 9. At the same time, the setting of the top column 55 can play a certain supporting role on the saddle casting 9.

[0035] As a preferred technical solution of the utility model: a guide rod 28 parallel to the screw rod 22 is fixed between the two bases 21, and the moving seat 23 is slidably mounted on the guide rod 28. The two guide rods 28 prevent the moving seat 23 from rotating circumferentially when moving.

[0036] As a preferred technical solution of the utility model: the top of the top column 55 and the top of the rotating wheel 33 are located in the same horizontal plane and are spherical structures. The spherical structure can not only support the saddle casting 9 but also reduce the friction between the saddle casting 9 and the bottom of the saddle casting 9, so that the saddle casting 9 can move more smoothly in the width direction.

[0037] As a preferred technical solution of the utility model: a mounting circular groove 8 for mounting on the rotating chassis of the grinding robot is opened at the bottom of the base plate 1. After the rotating chassis of the grinding robot is buckled in the mounting circular groove 8, the base plate 1 is fixed to the rotating chassis of the grinding robot by connecting bolts.

[0038] For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances; for technicians in this field, they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
