Description

Technical Field

[0001] The utility model relates to the field of fixture tools, in particular to a machine base processing tool. Background Art

[0002] like Figure 1 The machine base shown in the figure has a bottom plane and a flange surface on the machine base 1. The bottom plane and the flange surface are vertical structures. The bottom plane is the reference plane 11 for machining the bolt holes 12 on the subsequent flange surface, and has very high geometric tolerance requirements. In the past, the fixture for processing the bolt holes 12 on the flange surface of the machine base 1 was mainly a base plate + multiple equal-height blocks. The base to be processed was placed on the equal-height blocks, the bottom plane matched the equal-height blocks, and then locked vertically; the previous fixture form could only control the height of the machine base 1 to be in a horizontal state, but could not ensure whether the two ends of the machine base 1 were consistent in the front and rear directions, and it was easy for one end of the machine base to be forward and the other end to be backward. Therefore, the use of previous fixtures and tooling required the machine base to be "straightened" in the left and right directions, that is, the center line of the bolt hole on the flange surface of the machine base and the moving direction of the CNC machine drill bit were in the same straight line. If the machine base was not "straightened" during installation, there would be errors when processing the bolt holes on the flange surface, and there would be a risk of shape and position tolerance violations between the processed plane and the cast shape and the inner hole to be processed. Such shape and position tolerance violations can only be discovered through three-coordinate detection in subsequent processing or after the process is completed, which will inevitably bring great cost losses.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The present application provides a machine base processing tool, which is described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0033] In order to solve the technical problem that the positions of the bolt holes and the outer circle of the machine base casting are easily deviated when machining the bolt holes on the machine base flange surface in the prior art, an embodiment of the present application provides a machine base machining tool, which is described in detail below.

[0034] like Figures 1 to 5 As shown, a machine base processing tooling includes

[0035] Bottom plate 2;

[0036] A plurality of equal height blocks 21, each of which is fixedly connected to the base at its lower end, and each of which is adapted to abut against the reference surface 11 of the base 1 at its upper end, so that the base 1 is horizontal; a locking mechanism 5 is provided at the upper end of the equal height blocks 21, and the locking mechanism 5 is adapted to vertically lock the base 1 on the equal height blocks 21;

[0037] The left self-centering mechanism and the right self-centering mechanism, the two self-centering mechanisms 3 are arranged on the left and right sides of the base plate 2, the two self-centering mechanisms 3 cooperate with the machine base 1, and are suitable for keeping the center line of the machine base 1 in the left and right directions consistent with the left and right direction reference line of the tooling.

[0038] In this embodiment, the number of the equal-height blocks 21 is three.

[0039] Specifically, as an optional implementation in this embodiment, Figures 2 to 4 As shown, the self-centering mechanism 3 includes a V-shaped seat 31 and a pair of vertical floating mechanisms 4;

[0040] A V-shaped opening 32 is provided in the V-shaped seat 31, and the upper end of the vertical floating mechanism 4 is connected to the V-shaped seat 31, and the lower end is connected to the bottom plate 2;

[0041] In normal state, the V-shaped seat 31 floats upward, and when the machine base 1 is placed on the equal height block 21, the machine base 1 cooperates with the V-shaped opening 32 to adjust the machine base 1 to the center position of the V-shaped opening 32, and the machine base 1 presses down the V-shaped seat 31 to make the V-shaped seat 31 sink.

[0042] The positions of the left and right self-centering mechanisms 3 need to be designed in advance to ensure that the left and right V-shaped seats 31 are on the same axial line. This ensures that after the V-shaped seat 31 adjusts the center of the machine base 1, the entire machine base 1 is on the left and right center lines of the tooling, and controls the installation position of the entire machine base 1, that is, ultimately controls the bolt holes 12 of the machine base 1 to be in the correct position, ensuring that the drill bit can be quickly and accurately positioned during subsequent processing on the horizontal machining center, ensuring that the pitch circle of each bolt hole is concentric with the outer circle of the casting.

[0043] Specifically, as an optional implementation in this embodiment, Figure 4 As shown, the vertical floating mechanism 4 includes a lower guide seat 41, an upper guide block 42 and a compression spring 43;

[0044] The lower guide seat 41 is fixedly arranged on the bottom plate 2, and a guide hole is provided at the upper end thereof;

[0045] The upper guide block 42 is fixedly arranged at the lower end of the V-shaped seat 31, and a guide column is formed at its lower end. The guide column is inserted into the guide hole, and the compression spring 43 is sleeved on the guide column, and its upper and lower ends respectively abut against the upper guide block 42 and the lower guide seat 41.

[0046] The V-shaped seat 31 can only achieve elastic floating up and down through the two guide pillars at the lower end. When the V-shaped seat 31 does not carry the machine base 1, the two compression springs 43 can drive the V-shaped seat 31 to lift. When the machine base 1 is placed up, the V-shaped seat 31 moves down, and the entire machine base 1 is locked on the equal height block 21.

[0047] Specifically, as an optional implementation in this embodiment, Figure 5 As shown, the locking mechanism 5 includes a locking plate 51, a locking bolt 52 and a connecting column 53;

[0048] The rear end of the locking plate 51 is connected to the equal height block 21 via the connecting column 53. The locking plate 51 is suitable for rotating around the connecting column 53. The connecting column 53 limits the upward and downward movement of the locking plate 51. The locking plate 51 is provided with a long slot, and the locking bolt 52 passes through the long slot and is connected to the equal height block 21. When the locking bolt 52 rotates, it can drive the locking end of the locking plate 51 to bend and deform, thereby achieving compression of the machine base 1.

[0049] The use process of the practical machine base processing tooling is as follows: the machine base 1 is placed on two V-shaped seats 31, the V-shaped seats 31 are moved down, and finally the machine base 1 is placed on the equal height block 21. The machine base 1 cooperates with the two V-shaped seats 31, and the left-right center line of the entire machine base 1 is consistent with the left-right reference line of the tooling. Then the three locking plates 51 are used to vertically lock the machine base 1. Then, when processing on the horizontal machining center, the drill bit can be quickly and accurately positioned to ensure that the pitch circle of each bolt hole is concentric with the outer circle of the casting.
