Description

Technical Field

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

[0002] The bottom of the robot's third-axis housing needs to have multiple through holes for the third-axis housing to connect and fix. When the third-axis housing is directly placed in the working area of ​​the drilling machine for drilling, the third-axis housing is not fixed in position and is subjected to drill pressure. If uneven force occurs, it will slide, thus affecting the quality and position accuracy of the through hole.

[0003] Therefore, how to improve the quality and position accuracy of the through hole at the bottom of the third shaft housing has become an urgent problem to be solved by those skilled in the art. Utility Model Content

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

[0005] The utility model provides a robot third axis housing fixing fixture, comprising a bottom plate, on which are arranged:

[0006] A support rod, supporting the bottom of the third shaft housing;

[0007] A pressure plate applies downward pressure to the bottom of the third shaft housing;

[0008] A push rod is arranged horizontally and presses outwardly against the upper ends of two opposite side walls of the third shaft housing;

[0009] The top block presses outwardly against the upper ends of the other two inner side walls of the third shaft housing.

[0010] The third axis housing is fixed by the joint action of the support rod, pressure plate, push rod and push block, and the bottom plate is fixed to the drilling station of the drilling machine and fixed by bolts; in this way, the position of the third axis housing is stable and not prone to sliding, thereby improving the quality and position accuracy of the through hole; and after the third axis housing is fixed, the part of its bottom that needs to be drilled protrudes outward, so that there will be no obstruction when drilling.

[0011] The specific installation structure of the push rod and the push block is: a mounting plate is arranged above the pressing plate and is fixedly connected to the pressing plate through a connecting column; the push rod and the push block are both installed on the lower end surface of the mounting plate.

[0012] Since it is difficult to maintain a balanced pressure between the top block and the third shaft housing, if the forces between the top blocks are different, the position accuracy of the third shaft housing will be affected, so further improvements are made to solve this problem. Specifically, the top block is elastically connected to the mounting plate through a spring.

[0013] The movement stability of the top block directly affects the uniformity of the force on the third shaft housing. Based on this, a further improvement is that a slide groove is provided on the mounting plate, and the top block is clamped in the slide groove to achieve movement guidance.

[0014] The specific installation structure of the pressure plate is: the limit rod and the screw are threadedly connected on the bottom plate; the outer end of the pressure plate is clamped with the limit rod, the middle part is sleeved with the screw, and the inner end is connected to the third shaft housing; a locking nut is threadedly connected on the screw, and through its locking, the pressure plate applies pressure downward to the third shaft housing to fix it.

[0015] The contact area between the pressure plate and the third shaft housing directly affects the position stability of the third shaft housing. Based on this, a further improvement is that two symmetrically arranged contact plates are provided at the inner end of the pressure plate; the contact plates apply pressure to the third shaft housing.

[0016] The number and position of the support rods directly affect the stability of the housing supporting the third shaft. Based on this, a further improvement is that three support rods are provided, and their positions form a triangle.

[0017] The number and position of the push rods directly affect the stability of the position of the third shaft housing. Based on this, a further improvement is that the push rods are set to three corresponding to the support rods, and their positions are close to the corresponding support rods to form a triangle.

[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] Embodiment 1:

[0024] like Figure 1 and Figure 2As shown, the utility model discloses a robot third axis housing fixing fixture, comprising a rectangular bottom plate 1 and a mounting plate 6, which are parallel to each other and connected and fixed by a connecting column 7. Specifically, the connecting column 7 is set to be four symmetrically arranged, the lower end of which is threadedly connected to the bottom plate 1, and the upper end is fixedly connected to the mounting plate 6 by a nut.

[0025] The third shaft housing 30 is placed between the bottom plate 1 and the mounting plate 6 to achieve fixation. Specifically, three support rods 2 are provided on the bottom plate 1 to support the bottom of the third shaft housing 30. The support rods 2 are threadedly connected to the bottom plate 1 so that their height can be adjusted. Two of the support rods 2 support the front side of the third shaft housing 30, and the other one supports the rear side of the third shaft housing 30, so that the positions of the support rods 2 form an isosceles acute triangle, and the third shaft housing 30 has higher stability.

[0026] The front and rear sides of the bottom plate 1 are also equipped with a pressure plate 3, which applies downward pressure to the bottom of the third shaft housing 30 to fix it. The specific installation structure is as follows: the bottom plate 1 is threadedly connected with a limit rod 10 and a screw rod 11; the outer end of the pressure plate 3 is provided with a slot, which is engaged with the limit rod 10, the middle part is sleeved with the screw rod 11, and the inner end is connected to the third shaft housing 30. The screw rod 11 is threadedly connected with a locking nut 12, which is locked so that the pressure plate 3 applies downward pressure to the third shaft housing 30 to fix it.

[0027] Three connecting blocks are installed on the lower end surface of the mounting plate 6, and a horizontally arranged push rod 4 is threadedly connected to the connecting block to apply pressure to the inner wall of the top of the third shaft housing 30, and the pressure direction is directed to the outside. The push rod 4 corresponds to the support rod 2 and is located near the support rod 2, thereby also forming an isosceles acute triangle, making the position of the third shaft housing 30 more stable.

[0028] Two symmetrically arranged bottom plates 1 are also installed at the middle of the lower end of the mounting plate 6, and the outer ends of the bottom plates 1 are connected to the top blocks 5 through springs 8. Under the restoring force of the springs 8, the top blocks 5 are connected to the left and right sides of the inner wall of the third shaft housing 30 and pressurize the third shaft housing 30, so that the third shaft housing 30 is fixed. The setting of the springs 8 keeps the pressure of the top blocks 5 on the third shaft housing 30 balanced, and there will be no pressure inconsistency, thereby avoiding the position error of the third shaft housing 30 due to uneven force.

[0029] The third shaft housing 30 is fixed by the joint action of the support rod 2, the pressure plate 3, the push rod 4 and the push block 5, and the base plate 1 is fixed to the drilling station of the drilling machine by bolts; in this way, the position of the third shaft housing 30 is stable and not prone to sliding, thereby improving the quality and position accuracy of the through hole; and after the third shaft housing 30 is fixed, the part of its bottom that needs to be punched protrudes outward, so that there is no obstruction when drilling.

[0030] Embodiment 2:

[0031] Compared with the first embodiment, the difference is that a slide groove 9 is provided on the mounting plate 6, and the top block 5 is clamped in the slide groove 9 to achieve movement guidance, so that the third shaft housing 30 is subjected to balanced force.

[0032] Embodiment three:

[0033] Compared with the first embodiment, the difference is that two symmetrically arranged contact plates 13 are provided at the inner end of the pressure plate 3; the contact plates 13 apply pressure to the third shaft housing 30. The provision of the contact plates 13 increases the contact area between the pressure plate 3 and the third shaft housing 30, and the contact plates 13 are symmetrical with respect to the center line of the bottom of the third shaft housing 30, thereby further improving the position stability of the third shaft housing 30.

[0034] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description.
