Abstract
The utility model relates to a counterweight frock for turning of a coupler body with big hook, which comprises a counterweight rack body I and a counterweight rack body II, the counterweight rack body I and the counterweight rack body II are connected with the coupler body into a whole through being traversed into a safety pin hole and a braked wheel hole of the coupler body through a screw bolt, the counterweight rack body I and the counterweight rack body II are tensed and connected through a tightening screw bolt, the rack structure can realize the convenient assembly, the reliable locating and clamping and the flexible adjustment between the coupler bodies with big hooks. The frock solves the situations that the turning process is unstable, work pieces are eccentric, the circular degree of the holes has big errors, the precision of the machine tool is damaged when adding the counterweight by other method in the past, and the frock greatly improves the production efficiency and guarantees the turning quality.
Description
Technical field
The utility model frock technology relates to the processing and manufacturing of hook, belongs to petroleum machinery equipment manufacturing technology field.
Background technology
Coupler body is the vital part in the serial hook, with the part that its endoporus directly is connected lower shell, brake hoop, lock ring is arranged.The counterweight of turning coupler body adopts before my company from statically balanced angle, can't guarantee that the coupler body center of gravity is on the centre of gyration of lathe all the time in the process, cause processing back workpiece endoporus occur eccentric, deviation from circular from is big, large-scale internal thread machining quality can't guarantee, dangerous, influence problem such as machine tool accuracy.At this processing difficulties, we take new process, have designed a kind of novel frock, and this problem is effectively solved.
Summary of the invention
The utility model purpose is that the counterweight frock use in a kind of hook coupler body turning of design processing, and is accurate to have realized the frock counterweight, and workpiece, frock are easy to loading and unloading, locate reliable clamping, can guarantee crudy, raise the efficiency.
Specifically, a kind of hook coupler body turning processing counterweight frock, it comprises counterweight support body I and counterweight support body II, pass counterweight support body I and counterweight support body II and coupler body safety pin-and-hole and braked wheel hole with bolt counterweight support body I and counterweight support body II and coupler body linked together, and between counterweight support body I and the counterweight support body II by the turnbuckle tension and connect.
Be provided with the adjusting device of adjusting its weight at counterweight support body I and/or counterweight support body II.Described adjusting device is to be installed in adjustment pad I on counterweight support body I and/or the counterweight support body II with bolt.
Turnbuckle tension everywhere all design have preventing clamping place workpiece deformation and unsettled support set and cover, and all there is the pairs of anti-loose nut device turnbuckle end.In turnbuckle, be with adjusting pad II.
The beneficial effects of the utility model:
1, determines rational counter weight construction.Coupler body foundry goods complex contour is irregular, in order to make it reach balance, center of gravity is moved on the axis of rotation, and the problem such as tactical diameter, loading and unloading of considering lathe simultaneously thinks that counterweight and workpiece press close to lower and lower to be beneficial to turning process more steady, and we have designed the counterweight frock of frame structure.
2, reliable clamping device, locking device and adjusting device have been designed.Utilize safety pin axis hole on the coupler body, braked wheel hole counter weight device to be connected with workpiece with bolt.In tension place design devices such as support set are arranged.For guarantee to process turning course safety, design has the pairs of anti-loose nut device.Consider the unstable relatively of spray appearance and size, design has adjusting device.
3, according to the production actual state, carry out structural analysis, calculating by design software, utilize 3-D technology to carry out live simulation, guarantee the reasonable, accurate, practical of counterweight frock design of knowing clearly.
The utility model is compared with prior art: this frock is first from dynamically balanced angle design, and project organization is use first, and counter weight device is accurate.Can realize quick loading and unloading, the clamping of workpiece, frock, effectively guarantee crudy, raise labour efficiency.When using checking at the scene according to the hook counterweight frock of above-mentioned mentality of designing and method design, workpiece endoporus, end face centering reach designing requirement, solve all problems that influence product processing quality effectively, guaranteed product quality, realized the batch process of key component.

The specific embodiment
As shown in Figure 1 and Figure 2, a kind of hook coupler body turning processing counterweight frock, it comprises counterweight support body I 1 and counterweight support body II 4, pass counterweight support body I 1 and counterweight support body II 4 with bolt 7 and counterweight support body I 1 and counterweight support body II 4 linked together with coupler body with coupler body safety pin-and-hole and braked wheel hole, and between counterweight support body I 1 and the counterweight support body II 4 by bolt 7 tensions and connect.Counterweight support body I 1 is provided with the adjusting device of adjusting its weight.Adjusting device is to be installed in adjustment pad I 2 on the counterweight support body I 1 with bolt.This structure can realize that the center of gravity of frock, workpiece is all the time on the centre of gyration axis of workpiece.Bolt 7 tension everywhere all design have preventing clamping place workpiece deformation with unsettled support set 11 with overlap 6, and all there is the pairs of anti-loose nut device turnbuckle end, is with adjusting pad II 5 in turnbuckle 7.Counter-balanced carriage body structure blank can be weldment or foundry goods or steel plate bolt connection piece.
This hook coupler body turning processing designs from dynamically balanced angle with the counterweight frock, adopts frame structure.This structure can guarantee that the center of gravity of frock and workpiece is all the time on the centre of gyration axis of workpiece.This frame structure can realize and the hook coupler body between easy to loading and unloading, location reliable clamping, adjust flexibly.Utilize PROE three dimensional design technology, this counterweight frock is carried out Work condition analogue, guarantee the reasonable, accurate of counterweight frock design.The design of this frock can be satisfied the machined requirement of coupler body, solve in the past with other method add turning process that counterweight occurs not steadily, workpiece is eccentric, hole circle degree error big, the situation of destruction machine tool accuracy.Can significantly improve productivity ratio, guarantee crudy.
The utility model is used in operations such as processing coupler body series endoporus, the conical surface, groove, internal thread on the horizontal lathe, guarantees the machined requirement of part.
