Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a tooling and fixture for multi-hole parts. Background Technology

[0002] In the process of machining multi-hole parts, multiple holes need to be drilled in the parts. During the machining process, a fixture is needed to assist in clamping and limiting the parts, so that the parts can be stably limited during the machining process.

[0003] In practical work, the existing tooling fixtures have relatively complete structures and functions, which can meet basic usage requirements, but the following problems still exist:

[0004] In the process of machining porous parts, holes need to be drilled in different parts of the parts. However, the fixed position of traditional fixtures makes it impossible to drill holes in the parts held by the fixtures, which affects the machining process of porous parts.

[0005] Therefore, this utility model provides a tooling fixture for porous parts. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a tooling fixture for multi-hole parts.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a tooling fixture for multi-hole parts, comprising a base frame, wherein an adjustment limiting structure is provided on the inner wall of the base frame, the adjustment limiting structure comprising a mounting plate, both sides of the mounting plate being fixedly connected to the inner surface of the base frame, a hydraulic telescopic rod being fixedly mounted on the top of the mounting plate, a connecting plate being fixedly connected to the output end of the hydraulic telescopic rod, and a first rectangular connecting plate being fixedly connected to the top of the connecting plate; an auxiliary pressing structure is provided on the top of the connecting plate, the auxiliary pressing structure comprising a second rectangular connecting plate, a second rectangular frame being fixedly connected to one side of the second rectangular connecting plate, a second motor being fixedly mounted on the top of the second rectangular frame, and a second screw being fixedly connected to the output end of the second motor.

[0008] In a preferred embodiment, a first rectangular frame is fixedly connected to the top of the first rectangular connecting plate, a first motor is fixedly installed on one side of the first rectangular frame, a first screw is fixedly connected to the output end of the first motor, the two ends of the first screw have opposite thread directions, two first screw hole blocks are symmetrically threaded on the outer surface of the first screw, a first rectangular through hole is opened on one side of the first rectangular frame, a first slide rod is slidably connected to the inner wall of the first rectangular through hole, one side of the first screw hole block is fixedly connected to one end of the first slide rod, a clamping plate is fixedly connected to one end of the first slide rod, and a first rectangular protrusion is fixedly connected to one side of the clamping plate.

[0009] The technical effect of adopting the above-mentioned further solution is that: under the action of the first screw, the first screw hole block can be driven to move, which in turn can drive the clamping plate to move. At this time, the part can be clamped. The first rectangular frame and clamping plate and other components can move up and down under the action of the hydraulic telescopic rod, which can assist in clamping and fixing different parts of the part, thereby avoiding the situation that the clamping part cannot be drilled due to the clamping part being fixed.

[0010] In a preferred embodiment, the outer surface of the second screw is threaded with a second screw hole block, a second rectangular through hole is formed on one side of the second screw hole block, a third rectangular through hole is formed on one side of the second rectangular connecting plate, a second slide rod is fixedly connected to one side of the second screw hole block, the second slide rod is slidably disposed on the inner wall of the second rectangular through hole and the third rectangular through hole, an auxiliary pressure plate is fixedly connected to one end of the second slide rod, and a second rectangular protrusion is fixedly connected to the bottom of the auxiliary pressure plate.

[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the second screw and the second screw hole block, the second slide bar can be driven to move, which in turn can drive the auxiliary pressure plate to move, thereby enabling the parts to be assisted in limiting and fixing from top to bottom, and making it easier to drill holes on the side of the parts.

[0012] In a preferred embodiment, a fourth rectangular through hole is provided on both sides of the second rectangular frame, and a guide rod is slidably connected to the inner wall of the fourth rectangular through hole. One end of the guide rod is fixedly connected to one side of the second screw hole block.

[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the guide slide rod, it can cooperate with the fourth rectangular through hole to assist in limiting the second screw hole block, thereby allowing the second screw hole block to move along the second screw.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting an adjustable limiting structure, the position of the first rectangular frame can be adjusted under the action of the hydraulic telescopic rod, thereby adjusting the position of the clamping plate. This allows the clamping plate to move in opposite directions or towards each other, thus assisting in clamping and limiting the parts at different heights and positions. This also facilitates multi-hole drilling operations on the parts. By setting an auxiliary pressing structure, the auxiliary pressure plate can be driven to move under the action of the second screw and the second screw block, thereby pressing and fixing the parts from top to bottom. This makes it easier to operate the parts during side drilling. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-4 As shown, this embodiment provides a technical solution: a tooling fixture for multi-hole parts, including a base frame 1, an adjusting and limiting structure 2 provided on the inner wall of the base frame 1, the adjusting and limiting structure 2 including a mounting plate 21, the two sides of the mounting plate 21 being fixedly connected to the inner surface of the base frame 1, a hydraulic telescopic rod 22 being fixedly mounted on the top of the mounting plate 21, a connecting plate 23 being fixedly connected to the output end of the hydraulic telescopic rod 22, a first rectangular connecting plate 24 being fixedly connected to the top of the connecting plate 23; an auxiliary pressing structure 3 is provided on the top of the connecting plate 23, the auxiliary pressing structure 3 including a second rectangular connecting plate 311, a second rectangular frame 31 being fixedly connected to one side of the second rectangular connecting plate 311, a second motor 32 being fixedly mounted on the top of the second rectangular frame 31, and the output end of the second motor 32 being fixedly connected to the first rectangular frame 31. A second screw 33 is fixedly connected. By setting an adjustment limit structure 2, the position of the first rectangular frame 25 can be adjusted under the action of the hydraulic telescopic rod 22, thereby adjusting the position of the clamping plate 211. This allows it to move in conjunction with the first screw 27 and the first screw hole block 28, enabling the clamping plate 211 to move towards or away from each other. This allows for auxiliary clamping and limiting of parts at different heights and positions, facilitating multi-hole drilling operations on the parts. By setting an auxiliary pressing structure 3, the auxiliary pressure plate 37 can be moved under the action of the second screw 33 and the second screw hole block 34, thereby pressing and fixing the parts from top to bottom. This makes it easier to operate the parts during side drilling.

[0026] Going further, such as Figures 2-3As shown: A first rectangular frame 25 is fixedly connected to the top of the first rectangular connecting plate 24. A first motor 26 is fixedly installed on one side of the first rectangular frame 25. A first screw 27 is fixedly connected to the output end of the first motor 26. The two ends of the first screw 27 have opposite thread directions. Two first screw hole blocks 28 are symmetrically threaded on the outer surface of the first screw 27. A first rectangular through hole 29 is opened on one side of the first rectangular frame 25. A first slide rod 210 is slidably connected to the inner wall of the first rectangular through hole 29. One side of the first screw hole block 28 is fixedly connected to one end of the first slide rod 210. A clamping plate 211 is fixedly connected to one end of a sliding rod 210. A first rectangular protrusion 212 is fixedly connected to one side of the clamping plate 211. Under the action of the first screw 27, the first screw hole block 28 can be driven to move, which in turn can drive the clamping plate 211 to move. At this time, the part can be clamped. The first rectangular frame 25 and the clamping plate 211 and other components can move up and down under the action of the hydraulic telescopic rod 22, which can assist in clamping and fixing different parts of the part, thereby avoiding the situation where the clamping part cannot be drilled due to the clamping part being fixed.

[0027] The above solutions also suffer from the problem of frequent adjustments to the position of the clamping plate 211 when drilling lateral holes in parts with regular shapes, which is very inconvenient. Figure 4 As shown: In this solution, the outer surface of the second screw 33 is threadedly connected to a second screw hole block 34. A second rectangular through hole 35 is provided on one side of the second screw hole block 34, and a third rectangular through hole 312 is provided on one side of the second rectangular connecting plate 311. A second slide rod 36 is fixedly connected to one side of the second screw hole block 34. The second slide rod 36 is slidably disposed on the inner wall of the second rectangular through hole 35 and the third rectangular through hole 312. An auxiliary pressure plate 37 is fixedly connected to one end of the second slide rod 36, and a second rectangular protrusion 38 is fixedly connected to the bottom of the auxiliary pressure plate 37. Under the action of the second screw 33 and the second screw hole block 34, the second slide rod 36 can be driven to move, which in turn can drive the auxiliary pressure plate 37 to move. This allows the parts to be assisted in limiting and fixing from top to bottom, and makes it easier to drill holes on the side of the parts.

[0028] The above solution also has the problem of high friction and inconvenient positioning during the sliding of the second screw hole block 34 on the inner wall of the second rectangular frame 31. Figure 2 and Figure 4 As shown, a fourth rectangular through hole 39 is provided on both sides of the second rectangular frame 31. A guide slide rod 310 is slidably connected to the inner wall of the fourth rectangular through hole 39. One end of the guide slide rod 310 is fixedly connected to one side of the second screw hole block 34. Under the action of the guide slide rod 310, it can cooperate with the fourth rectangular through hole 39 to assist in limiting the second screw hole block 34, so that the second screw hole block 34 can move along the second screw 33.

[0029] Working principle:

[0030] like Figure 1-4 As shown:

[0031] In use: Place the object on top of the bottom frame 1. Then activate the hydraulic telescopic rod 22, which will drive the connecting plate 23 to move, thereby adjusting the position of the clamping plate 211. At this time, activate the first motor 26, which will drive the first screw 27 to move the first screw hole block 28, thereby driving the first slide rod 210 to slide on the inner wall of the first rectangular through hole 29, thereby driving the clamping plate 211 to move.

[0032] When it is necessary to press down and fix the top, the second motor 32 is started, so that the second screw 33 can drive the second screw hole block 34 to move, which in turn can drive the second slide bar 36 to move, which in turn can drive the auxiliary pressure plate 37 to move, and at the same time can drive the guide slide bar 310 to slide on the inner wall of the fourth rectangular through hole 39.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
