A tool for maintaining the positional accuracy of a casting

Abstract

The application discloses a jig for keeping the position degree of a casting, which comprises a jig for keeping the vertical position degree of the main platform and the side platform of the casting. The side platform positioning block pulls the side platform of the casting to tightly adhere to the positioning baffle, and the locking pressing plate is used for pressing the main platform of the casting to adhere to the top surface of the base, so that the vertical position degree of the main platform and the side platform of the casting which have been kept perpendicular is kept during the repair welding process, and the problem that the position degree of the main platform and the side platform needs to be kept perpendicular when the two parts cannot be tightly pressed for the repair welding of the casting in the prior art is solved.

Description

Technical Field

[0001] This invention relates to a tooling for maintaining the position of a casting, belonging to the field of auxiliary tooling technology for casting production. Background Technology

[0002] The main platform 12 and side platforms 13, with a mutual perpendicularity of 0.5, constitute the casting 11. The casting structure is as follows: Figure 3 , Figure 4 As shown, the main platform 12 and the side platform 13 are prone to deformation when heated during the welding process, which causes the perpendicularity of the main platform 12 and the side platform 13 to fail to meet the requirements. In order to maintain the perpendicularity of the main platform 12 and the side platform 13 on the casting, auxiliary tooling is required.

[0003] Existing welding fixtures, such as Chinese Patent Publication No. CN206185370U, can only clamp two parts together to maintain their state during welding, but cannot maintain the perpendicularity of the main platform and the side platform when repairing the casting. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a tooling for maintaining the positional accuracy of castings.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a tooling for maintaining the positional accuracy of a casting, comprising:

[0007] A tooling fixture that can maintain the vertical position of the main platform and the side platform on the casting.

[0008] Includes: base;

[0009] A locking plate that presses the main platform of the casting together; the locking plate is detachably and fixedly installed on the front side of the top face of the base.

[0010] Vertical positioning baffle, side platform positioning block, side platform limiting block. The vertical positioning baffle can be detachably fixed to the rear side of the top surface of the base. The vertical positioning baffle is used to control the size of the casting to fit tightly.

[0011] A side platform positioning block is detachably fixed on the vertical positioning baffle, and a side platform limiting block is fixed on the side platform positioning block.

[0012] The side platform positioning block can be detachably fixed on the vertical positioning baffle by locking screw B.

[0013] The base is fixed with lifting rods on opposite sides of its exterior.

[0014] The lifting rod is detachably screwed onto the opposite side of the base via a threaded joint.

[0015] The lifting rods consist of four rods, which are installed in pairs on opposite sides of the base. The base has a through hole in the middle, and a support ring inside the through hole is used to contact and limit the bottom of the casting.

[0016] A locking plate is detachably and fixedly installed on the front side of the top surface of the base via a locking screw A. The locking plate is used to press down the top edge of the main platform of the casting.

[0017] The base has a positioning hole on the rear side of the top surface, into which a main platform corner positioning pin is inserted. The main platform corner positioning pin can be inserted into or removed from the positioning hole on the rear side of the top surface of the base. The main platform corner positioning pin is inserted from the main platform through hole of the casting into the positioning hole on the rear side of the top surface of the base, thereby realizing the positioning of the main platform of the casting by the main platform corner positioning pin.

[0018] The beneficial effects of this invention are as follows: the side platform positioning block pulls the side platform of the casting tightly against the positioning baffle, and the locking plate is used to press the main platform of the casting against the top surface of the base, ensuring that the vertical position of the main platform and the side platform, which are already perpendicular to each other on the casting, is maintained during the welding process. This solves the problem that the existing technology cannot maintain the vertical position of the main platform and the side platform when welding the casting by clamping the two separate parts.

Detailed Implementation

[0024] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0025] like Figures 1 to 2 As shown.

[0026] This application discloses a tooling for maintaining the positional accuracy of a casting, comprising:

[0027] The base 1 is fixed with lifting rods 9 on the opposite outer side. The lifting rods 9 are detachably screwed onto the opposite outer side of the base 1 by threaded joints. There are four lifting rods 9, which are installed in pairs on the opposite outer side of the base 1.

[0028] The base 1 has a through hole in the middle, and a main platform support ring 7 is provided to contact and limit the bottom of the main platform 12 of the casting 11. The main platform support ring 7 prevents the main platform 12 from becoming elliptical.

[0029] A locking plate 2 is detachably and fixedly installed on the front side of the top surface of the base 1 via a locking screw A8. The locking plate 2 is used to press down the top edge of the main platform 12 of the casting 11. A positioning hole is provided on the rear side of the top surface of the base 1 to insert and install the corner positioning pin 6 of the main platform. The corner positioning pin 6 can be inserted into or removed from the positioning hole on the rear side of the top surface of the base 1. The corner positioning pin 6 is inserted from the through hole of the main platform 12 of the casting 11 into the positioning hole on the rear side of the top surface of the base 1, so as to realize the positioning of the main platform 12 of the casting 11 by the corner positioning pin 6.

[0030] A vertical positioning baffle 3 is detachably fixed to the rear side of the top surface of the base 1 by bolts. The vertical positioning baffle 3 is used to control the size of the casting 11 to fit tightly. A side platform positioning block 4 is detachably fixed to the vertical positioning baffle 3 by locking screw B10. The side platform positioning block 4 is used to pull the side platform 13 of the casting 11 tightly against the positioning baffle 3. A side platform limiting block 5 is fixed to the side platform positioning block 4. The side platform limiting block 5 is used to limit the concave deformation of the side platform 13 of the casting 11.

[0031] After casting 11 is placed on base 1, the bottom of the main platform 12 of casting 11 engages with the main platform support ring 7 in the through hole in the middle of base 1. The main platform 12 of casting 11 is positioned by the main platform corner positioning pin 6. The locking plate 2 presses down on the main platform 12 of casting 11. The side platform positioning block 4, with the side platform limiting block 5, is fitted onto the side platform 13 of casting 11. The side platform positioning block 4 is fixed to the vertical positioning baffle 3 by the locking screw B10. The side platform positioning block 4 pulls the side platform 13 of casting 11 tightly against the positioning baffle 3. The locking plate 2 is used to press the main platform 12 of casting 11 against the top surface of base 1, ensuring that the vertical position of the main platform 12 and the side platform 13, which are already perpendicular to each other on casting 11, is maintained during the welding process. This solves the problem in the existing technology where the two separate parts are clamped together but the casting cannot be welded, and the vertical position of the main platform and the side platform must be maintained. Then, it is hoisted to the vacuum welding box by the hoisting rod 9 for welding.
