Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a milling fixture for a robot second axis shell. Background Art

[0002] The front side and bottom surfaces of the robot's second axis housing are milled to ensure that their flatness and verticality meet usage requirements.

[0003] During processing, the second axis housing needs to be flipped 90°. The flipping process will affect the position accuracy of the second axis housing, thereby affecting the verticality of the front side and bottom surfaces. Utility Model Content

[0004] In order to solve the technical problems in the background technology, the utility model discloses a robot second axis housing milling fixture.

[0005] The utility model provides a robot second axis housing milling fixture, comprising a base, the second axis housing bottom is clamped on the base with the bottom facing upward, and two symmetrically arranged connecting plates are arranged at the bottom of the second axis housing; the base is provided with:

[0006] The support column is arranged vertically and used to support the connecting plate upwards;

[0007] The first push rod is arranged horizontally and is used for the rear end installation limit of the connecting plate;

[0008] The second push rod is arranged horizontally and perpendicular to the first push rod, and is used for installation and limiting on one side of the second shaft housing;

[0009] The pressure plate applies pressure to the front end of the connecting plate to fix the second shaft housing.

[0010] The second shaft housing is installed and limited by the support column, the first push rod and the second push rod, and is fixed by the clamping action of the first push rod and the pressure plate. With this arrangement, the second shaft housing does not need to be flipped, and can be formed by milling the bottom surface and the front side surface in sequence, with higher flatness and verticality.

[0011] In order to enable the support column to stably support the second shaft housing, a further design is that the lower end of the support column is threadedly connected to the base so that its height is adjustable.

[0012] When the second shaft housing is being processed, vibration may cause the support column to spin and its height may change. Based on this, a further improvement is that a locking nut is threadedly connected to the lower end of the support column to fix the support column after adjustment.

[0013] In order to improve the position accuracy of the first push rod and the second push rod, a further improvement is that the first push rod is threadedly connected to the base so that its horizontal position can be adjusted. The second push rod is threadedly connected to the base so that its horizontal position can be adjusted.

[0014] When the second shaft housing is installed, it will be blocked by the pressure plate. Based on this, further improvements are as follows: two first screws and second screws arranged in parallel are provided on the base; the outer end of the pressure plate is clamped with the first screw, and the middle part is sleeved with the second screw to achieve installation positioning, and the other end is against the connecting plate; a fixing nut is threadedly connected to the second screw, and the pressure plate is pressed against the connecting plate by locking it. In this way, the pressure plate can be detachably installed. When the second shaft housing is installed, the pressure plate is first removed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] like Figure 1-5 As shown, the utility model discloses a robot second axis housing milling fixture, including a horizontally arranged base 1, a second axis housing 30 is clamped on the base 1, two symmetrically arranged connecting plates 31 are provided at the bottom of the second axis housing 30, and the lower end of the connecting plate 31 is a bottom surface 32; the front side surface 33 of the second axis housing 30 is perpendicular to the bottom surface 32.

[0024] The base 1 includes a bottom plate 11, a base plate 12 is vertically connected to the bottom plate 11, and two horizontally arranged first push rods 3 are threadedly connected to the base plate 12, which are used to install and limit the rear end of the connecting plate 31. The two ends of the base plate 12 are vertically connected to the side plates 13 to form a U-shaped groove, and the second shaft housing 30 is installed in the U-shaped groove with its bottom surface 32 facing upward and the front side surface 33 facing outward. One of the side plates 13 is threadedly connected to a horizontally arranged second push rod 4, which is used to install and limit the side of the second shaft housing 30.

[0025] The open end of the side plate 13 is connected to a mounting plate 14 extending outward. The mounting plate 14 is threadedly connected to two first screw rods 7 and second screw rods 8 arranged in parallel, and the connection between the mounting plate 14 and the mounting plate 14 is locked and fixed by a nut connected by thread. The outer end of the pressure plate 5 is provided with a card slot, which is clamped with the first screw rod 7, and the middle part is sleeved with the second screw rod 8 to achieve installation and positioning, and the other end is against the connecting plate 31; the second screw rod 8 is threadedly connected to a fixing nut 9, and the pressure plate 5 is locked to the connecting plate 31. In this way, the pressure plate 5 can be detachably installed. When the second shaft housing 30 is installed, the pressure plate 5 is first removed to provide sufficient installation space for the second shaft housing 30.

[0026] Three vertically arranged support columns 2 are installed at the position of the bottom plate 11 inside the U-shaped groove to support the connecting plate 31. The support columns 2 are threadedly connected to the bottom plate 11 so that their height can be adjusted. A locking nut 6 is threadedly connected to the connection between the support column 2 and the bottom plate 11 for locking and fixing the support column 2. By adjusting the height of the support column 2, it can stably support the connecting plate 31, thereby improving the position stability of the second shaft housing 30.

[0027] The second shaft housing 30 is installed and limited by the support column 2, the first push rod 3 and the second push rod 4, and is fixed by the clamping action of the first push rod 3 and the pressure plate 5; with such a configuration, the second shaft housing 30 does not need to be flipped, and can be formed by milling the bottom surface 32 and the front side surface 33 in sequence, with higher flatness and verticality.
