Abstract
The utility model discloses an adjustable clamp, which is mainly used for sawing up a common connection rod of an engine. The adjustable clamp is characterized in that a side plate with a kerf is fixedly mounted on a bottom plate; a cushion block is fixedly mounted on the side plate; a directional element is fixedly mounted on the right side of the cushion block; a replaceable location block is mounted between the directional element and a slide plate through a bolt penetrating the directional element and the slide plate; a replaceable centering shaft is mounted at the center of the slide plate; and a replacement location block is mounted between the bottom plate and the cushion block. The practical use proves that the adjustable clamp can radically overcome the disadvantage that a plurality kinds of clamps are required for sawing up varieties of connection rod blanks, thereby reducing consumption of clamp materials as well as the time and management cost. Accordingly, the adjustable clamp can be used for sawing up different varieties of connection rod blanks, thereby effectively reducing the production cost and meeting the requirements for multi-variety and small-batch production.
Description
One, technical field
The utility model belongs to a kind of mechanical sawing clamp for machining, is mainly used in the sawed-off processing of engine plain connecting rod.
Two, background technology
At present the sawed-off processing technology of plain connecting rod be with the major part nose end of connecting rod blank sawed-off after, finish the processing of subsequent handling again, as shown in Figure 1, B is sawed-off a mouthful of connecting rod blank.Former sawed-off anchor clamps are shown in Fig. 2,3, and it is made up of side plate 1, base plate 2, pin 3, screw 4, apotting spindle 5, side locating piece 6.The apotting spindle 5 of during work the microcephaly hole of many connecting rod blanks 7 being packed into successively, many connecting rod blank 7 big end hole sides abut against on the side locating piece 6, the hydraulic clamp mechanism of band sawing machine clamps workpiece, and bands for band carries out the sawed-off processing to sawed-off mouthful of B under the driving of motor.It is that height is renderd a service in a kind of equipment less investment, production, technology is simple, the machining that processing cost is low, but can only process the connecting rod blank of a kind in actual use, promptly sawed-off anchor clamps can only be processed a kind of connecting rod blank of specification, the connecting rod blank of processing plurality of specifications just needs many kinds of anchor clamps, the processing connecting rod is serial more in the production, just need the above special-purpose sawed-off anchor clamps of hundred kinds, anchor clamps manufacturing cost first mate degree increases like this, anchor clamps are various in style to make troubles to management, the modern many kinds of incompatibility, batch production requirement.
Three, utility model content
The main technical problems to be solved in the utility model and purpose are: according to the deficiency of existing sawed-off anchor clamps existence, by improving, a kind of adjustable sawed-off clamp for machining of general connecting rod is provided, by changing element, just be adapted to the sawed-off processing of different cultivars connecting rod blank, fundamentally overcome the defective that a kind of anchor clamps are exclusively used in a kind of connecting rod blank of processing, realize reducing manufacturing, the management cost of sawed-off anchor clamps, satisfy many kinds, the requirement of small lot batch manufacture.
Main technical schemes of the present utility model is: on base plate, with pin and side plate that has saw kerf of screw fixed installation, be screwed the installation cushion block on the left side of side plate, its the right fixedly mounts the directed part of a U type with screw ` and pin, the bolt of band spring passes the directed part of U type and is threaded with slide plate, between directed part of U type and slide plate, an interchangeable locating piece is installed, an interchangeable centration axis is installed in the middle of slide plate, by screw an interchangeable locating piece is installed in the lower right of base plate and cushion block.
The utility model proves by practical application: reach purpose of design fully, overcome the connecting rod blank of producing a plurality of kinds and done the problem of assurance with regard to needing multiple sawed-off anchor clamps, saved a large amount of clamp materials, man-hour, the place of putting instrument and personal management.Really accomplished on sawed-off anchor clamps,, just be adapted to the sawed-off processing of different cultivars connecting rod blank, reduced production cost effectively, satisfied the demand of many kinds, small lot batch manufacture by changing relevant elements.
Four, description of drawings
Below in conjunction with accompanying drawing the utility model is done to describe in further detail.
Fig. 1 is the schematic diagram of connecting rod blank and sawed-off mouth thereof.
Fig. 2 is the front view of existing sawed-off clamp structure.
Fig. 3 is the left view of Fig. 2.
Fig. 4 is the front view of the utility model structure.
Fig. 5 is the left view of Fig. 4.
Five, the specific embodiment
With reference to Fig. 4,5, the utility model is made up of the directed part of base plate 1, side plate 2, pin 3, screw 4, slide plate 11, screw 12, connecting rod blank 7, the bolt 8 of band spring, U type 9, two cushion blocks 10, interchangeable centration axis H1, interchangeable locating piece H2, interchangeable locating piece H3 etc.
With reference to Fig. 4,5, main technical schemes explanation of the present utility model: on base plate 1, with pin 3 and side plate 2 that has saw kerf of screw 4 fixed installations, the left side at side plate 2 fixedly mounts cushion blocks 10 with screw 12, its the right fixedly mounts the directed part 9 of a U type with screw `12 and pin, the bolt 8 of band spring passes the directed part 9 of U type and is threaded with slide plate 11, between directed part of U type and slide plate, an interchangeable locating piece H3 is installed, an interchangeable centration axis H1 is installed in the middle of slide plate 11, by screw 12 an interchangeable locating piece H2 is installed in the lower right of base plate 1 and cushion block 10.
With reference to Fig. 4,5, for satisfy different connecting rod blank centre-to-centre spacing L (130～145mm) processing request, the thickness of H3 can be made into: 5,5.1,5.2,5.3 ... 15 series; For satisfy different connecting rod blank big end hole sides apart from S (32～45mm) processing request, the width of H2 can be made to be become: 5,5.1,5.2,5.3 ... 13 series; For satisfy different connecting rod blank microcephaly bore dias (processing request of Φ 16～30mm), the diameter of H1 can be made into: 16,16.1,16.2,16.3 ... 30 series.
With reference to Fig. 4,5,1, operation principle of the present utility model: (the locating piece H3 of a corresponding thickness is installed in 130～145mm) requirements between directed part 9 of U type and slide plate 11, compress with the bolt 8 of being with spring according to the centre-to-centre spacing L of different connecting rod blanks; According to the side of different connecting rod blank big end holes apart from S (32～45mm) requirements, the locating piece H2 that a corresponding width is installed on base plate 1 is fixing with screw 12; (the centration axis H1 of a corresponding diameter is installed in Φ 16～30mm) requirements on slide plate 11, this moment, sawed-off anchor clamps assembling was finished according to microcephaly's bore dia of different connecting rod blanks.Again anchor clamps are installed to the processing that just can finish on the band sawing machine sawed-off mouthful of B of connecting rod blank.By changing above three interchangeable serial part H1, H2, H3, just can realize finishing sawed-off processing to the connecting rod blank of different size kind.
