The rotatable rigid rotation angle bearing comprises a first locating block, an adjusting shaft, a second locating block, a gasket, a rotation angle bearing, a pin shaft, a cylindrical head inner hexagon screw and the like. A locating pin shaft is used for rotatably connecting the center pinhole of the rigid rotation angle bearing with a foundation plate, the locating pin shaft is also used for rotatably connecting the pin shaft hole of the second locating block with the foundation plate, the locating pin shaft is also used for rotatably connecting the pin shaft hole of the first locating block with the rigid rotation angle bearing, so that the position of the second locating block on the adjusting shaft can be adjusted and different lengths L can also be obtained; and meanwhile, the rotated angle alpha of the rigid rotation angle bearing can be calculated by using a trigonometric function.

Description

Can revolve the supporting of rigidity corner

Technical field:

A kind of revolved rigidity corner that is used for mechanical industry built-up jig supports, and belongs to the technical field of the built-up jig apparatus structure of Aided Machine processing.

Background technology:

In the dowel-pin modular fixture, the effect of corner supporting is: when the corner supporting needs to rotate a certain angle, must carry out the rotation that stepping has level by the angle that the angle cushion block is set, then with bolt locking, this corner supporting shortcoming in use is:

The connection that the corner supporting member is adjacent between the part does not have the cylinder alignment pin, and after with bolt locking, the pressing friction power that can only lean on the corner supporting member to be adjacent between the part keeps relative position constant.Do not belong to rigidity and be located by connecting, the reliability of location is relatively poor relatively.

The angle that the corner supporting is rotated can only have the level adjustment and not accomplish stepless linear adjustment by stepping.

The present invention provides a kind of and can accomplish that with cylinder alignment pin rigidity location the revolved rigidity corner supporting of high-precision stepless linear regulation is arranged in the time of accomplishing to rotate again.

Summary of the invention:

A kind of revolved rigidity corner supporting of built-up jig; Comprise: first, second and third cylinder pin hole 01,02,04, can revolve rigidity corner supporting 03, packing ring 05-002,05-006; Hexagonal spiral shell 05-001,05-007 in the socket cap; The first locating piece 05-003, the second locating piece 05-005, regulating shaft 05-004; It is characterized in that,

Saidly revolve rigidity corner supporting 03 and be square rigid plate, first cylinder pin hole 01 on it can be done rotatable the connection with soleplate through alignment pin;

The said second locating piece 05-005 is special-shaped rigid body, and the 3rd pin-and-hole 04 on it can be done rotatable the connection with soleplate through alignment pin;

Said: the first locating piece 05-003 is special-shaped rigid body, second cylinder pin hole 02 on it through alignment pin with can revolve the rigidity corner and prop up and make rotatable the connection;

Internal thread on the said second locating piece 05-005 and the external screw thread on the regulating shaft 05-004 match; When regulating the relative position of internal and external threads; Promptly changed the length of L; Making second pin-and-hole 02 is the center with first pin-and-hole 01, and the length of first pin-and-hole to the second pin-and-hole is the circle rotation of radius, thereby has changed the orientation angle that can revolve rigidity corner supporting 03.

Description of drawings:

Fig. 1 is the assembling sketch map:

The specific embodiment:

Use the cylinder alignment pin, first cylinder pin hole 01 that can revolve rigidity corner supporting 03 and the pin-and-hole of locating soleplate are done rigidity and can be revolved and be connected.

Use the cylinder alignment pin, corresponding pin-and-hole on the three cylindrical pin-and-hole 04 of the second locating piece 05-005 and the location soleplate is done rigidity can revolve connection.

First and third preceding two cylinder dowel hole 01 and 04 spacing are set at 80 millimeters.

Use the cylinder alignment pin, the pin-and-hole that can revolve second cylinder pin hole 02 and the first locating piece 05-003 in the rigidity corner supporting 03 is done and can be revolved pin joint.

Second locating piece 05-005 endoporus vertically has the internal thread of M 14X 1.5 and the external screw thread of the M 14X 1.5 on the regulating shaft 05-004 to match; When the second locating piece 05-005 rotate on regulating shaft 05-004 when mobile through inner hole thread; Can adjust the relative position of the two, i.e. the length of L.After having adjusted, lock simultaneously, to keep rigidity with socket cap hexagon socket head cap screw 05-001 and the 05-007 of M8.

When the relative position of second cylinder pin hole 02 and three cylindrical pin-and-hole 04 changes; When being the length variations of L; Because the pin-and-hole on second locating piece is connected and can not moves through cylindrical pin with soleplate; This will make rigidity corner supporting 03, the alignment pin on warp second cylinder pin hole 02 drive and center on first cylinder pin hole 01 and do rotation, change thereby accomplish rigidity

The angle is bearing in the adjustment of being done around first cylinder pin hole 01 on the X Y plane at any angle.

As assemble shown in the picture group, the length computation formula of L is following:

$L=\sqrt{{\left(\mathrm{CX}\sin \mathrm{\α}\right)}^2+{(80-\mathrm{CX}\cos \mathrm{\α})}^2}$

Explain:

1. the start angle at α angle is: 32 ° of 31.998 ° of ≈ are set at 0 °.

2.0 ° the time, the distance of dowel hole 01 to dowel hole 02 is 37.74 millimeters of constants.

3. when angle changes by 0 °～45 °, and undertaken by the interval of 1 ° of each variation, the length of L is also corresponding to fade to 80.41 millimeters by 51.99 millimeters.Detailed delta data such as subordinate list:

Annotate: the length of L is millimeter.
