Abstract
The invention provides a production process of a high-precision connecting plate. The production process includes: measuring bolt hole diameter and relative positions of a device body, and determining a borehole size on a sample plate according to the data; processing a glasses plate tightly matched with hinged hole bolts; connecting the sample plate to the device body through the drilled glasses plate, and fixing the glasses plate to the sample plate by welding, and removing the sample plate. A gap between the glasses plate and each hinged hole bolt is smaller than 0.1mm. Original connecting plate bolt holes can be drilled with the sample plate, the relative position of each bolt hole is guaranteed within the tolerance range, and the high-precision connecting plate is obtained.
Description
Technical field
The present invention relates to the high accuracy connecting plate and make, be particularly useful for replacing and the making of multiple plant equipment connecting portion articulation hole connecting plate.
Background technology
Main equipment assembles with connecting plate is accurate, as driving, straddle truck etc., connecting plate is to join the drilling bolt that drills and reams to be connected with equipment. when in the equipment use if needs are made again when the situations such as damage, distortion of connecting plate take place, use survey tool can't guarantee that the relative position of each bolt hole is in the margin of tolerance, connecting plate is made and is not only taken a lot of work but also time-consuming, and machining accuracy is difficult to be ensured.
The present invention is according to the measurement data of the on-the-spot plant equipment connecting portion diameter of bolt and pitch-row, hole at model, its aperture connects much larger than reality uses bolt hole, the cheater plate of reprocessing respective numbers, this cheater plate and articulation hole bolt closely cooperate, model and all cheater plate and equipment are linked as one, adopt cheater plate and model the method for local welding to fix, remove model, join brill connecting plate bolt hole with this model, can produce satisfactory high accuracy connecting plate simply and easily by above step, have important production practices and be worth.
Summary of the invention
The objective of the invention is to: utilize cheater plate to be connected model with the large aperture and join according to the actual size in equipment connecting bolt hole and get out the high accuracy connecting plate, satisfy the position of related features requirement of all bolts hole, this implementation method is simple and efficient.
The object of the present invention is achieved like this: a kind of manufacture craft of high accuracy connecting plate, and accessory is made of former connecting plate, cheater plate, model, apparatus body and bolt;
Implementation step: bolt aperture and the relative position of measurement device body 4, determine bore size on the model 3 with these data; Reprocessing and the articulation hole bolt cheater plate 2 that closely cooperates, wherein cheater plate 2 and the gap of articulation hole bolt are less than 0.1mm; With the cheater plate 2 of joining brill model 3 is connected on the apparatus body 4, fixing with model 3 welding cheater plate 2, remove model 3, join as model 3 with this and bore former connecting plate 1 bolt hole, guarantee that the relative position of each bolt hole in the margin of tolerance, namely gets high accuracy connecting plate 5.
Know-why of the present invention: the connecting plate manufacture craft is to measure the pitch-row of bolt hole by the original link position of equipment, make model according to this measurement data, the model diameter of bolt hole is greater than joining the auger shell keyhole, with the cheater plate of joining brill model is connected on the equipment, adopt cheater plate and model the method for local welding to fix, remove model, join brill connecting plate bolt hole as model, the connecting plate that utilizes this technology to produce guarantees that the relative position of each bolt hole in the margin of tolerance, shows technological progress.
Description of drawings
The present invention is described further by reference to the accompanying drawings.
Accompanying drawing 1 is the front view of former connecting plate;
As shown in the figure: the former connecting plate of 1-.
Accompanying drawing 2 is the bolt pass layout vertical view of model.
As shown in the figure: the 2-cheater plate.
Accompanying drawing 4 connects cheater plate B generalized section for model;
As shown in the figure: 2-cheater plate, 3-model, 4-apparatus body.
Accompanying drawing 5 is made the A generalized section for the high accuracy connecting plate;
As shown in the figure: 2-cheater plate, 3-model, 5-high accuracy connecting plate.
The specific embodiment
The present invention is described further in conjunction with the embodiments.
Embodiment
Plant equipment attaching parts of the present invention (as Fig. 1) in use because the damage of connecting plate or distortion need to make again, but the connecting plate bolt hole is to join to bore to process, relative positional accuracy is had relatively high expectations. on-the-spot actual measurement can't guarantee its precision.Now adopt novel process, according to the bolt hole distance of measuring, in template boring (as Fig. 2), its aperture connects much larger than reality uses bolt hole. the cheater plate (as Fig. 3) of reprocessing respective numbers, this cheater plate and articulation hole bolt closely cooperate, model and all cheater plate and equipment are linked as one (as Fig. 4), adopt the method for local welding to fix cheater plate and template, remove model, join brill connecting plate bolt hole (as Fig. 5) with this model, just can produce satisfactory high accuracy connecting plate by above step.
Be connected to example with 32 tons of driving end carriages: its every connecting plate has 48 bolts hole, with articulation hole bolt (M16) crane beam is linked together (as Fig. 1); A connecting plate disappearance causes end carriage to connect in disassembly process, but the connecting plate bolt hole is to join to bore to process, and the accumulated error of relative position can't accurately be measured the relative position of bolt hole less than 0.1mm; Adopt this technology, according to the bolt hole distance of measuring, in template boring (as Fig. 2), its aperture connects much larger than reality uses bolt hole, the cheater plate (as Fig. 3) of reprocessing respective numbers, and the fit clearance of this cheater plate and articulation hole bolt is less than 0.1mm, model and all cheater plate and equipment are linked as one, used bolted (as Fig. 4) adopts the method for local welding to fix cheater plate and model again, and sample making finishes; Remove model, join with this model and bore connecting plate bolt hole (as Fig. 5), and articulation processing, the relative positional accuracy of processing back bolt hole satisfies the equipment installation requirement fully, and the high accuracy connecting plate is made successfully, docks with this connecting plate end carriage of will driving a vehicle smoothly.
