Description
Technical field
This utility model relates to machinery processing apparatus technical field, is specially a kind of two pawl eccentric clamping devices.
Background technology
At present, machining has a lot of right angle tubular members, owing to its center carpenters square cun requires higher, conventional workpiece machining clamp is adopted to tend not to meet requirement, modal fixture then adopts the connection dish changed on lathe spindle and scroll chuck, again make floral disc, after floral disc is connected with main shaft, then the vehicle clamper additionally designed is contained on floral disc by interference fit and bolted pattern.The shortcoming of the program is: 1, fabrication cycle is long.2, dismounting repeatedly, installation spindle coupling disc, can reduce main shaft and the dimensional accuracy of connection dish, affects the machining accuracy of follow-up conventional axial workpiece.3, because lathe model is different, the interface pattern of main shaft and connection dish and size can be different, cause that the physical dimension of floral disc and pattern also can be different.Therefore, how overcoming the shortcoming that above fixture exists, it is achieved fast aligning part machining center on lathe, and can be connected on lathe soon by conventional connected mode, thus improving production efficiency, this is that union elbow produces the difficult problem that must first solve.
Summary of the invention
This utility model is solved the technical problem that to be in that to provide a kind of two pawl eccentric clamping devices, with the problem solving to propose in above-mentioned background technology.
This utility model is solved the technical problem that and is realized by the following technical solutions: a kind of two pawl eccentric clamping devices, including apparatus for fastening, fixing seat, apparatus for fastening is arranged on fixing seat, described apparatus for fastening includes gear shaft, eccentric hoop, eccentric adjusting sleeve, hands handle, straight pin, fixing bar, described straight pin inserts in the hole, location on eccentric adjusting sleeve, eccentric strap is on eccentric adjusting sleeve, then rotating eccentric sleeve cylinder, gear shaft will be installed the woodruff key end circular hole through fixing bar, fixing bar lower end is arranged on fixing seat, described fixing seat includes longitudinal lifting platform, it is fixedly installed on the turnover bracket on longitudinal lifting platform and rotating seat, described turnover bracket is provided with turntable, motor, described rotating seat is that longitudinal direction is fixedly mounted on turntable.
Described eccentric adjusting sleeve is connected with the woodruff key on gear shaft by keyway, with the end face circular bosses of the centre bore of flange traverse eccentric adjusting sleeve, by the circumferential apertures on flange, flange and fixing bar is connected and fixed with bolt.
The open end of described eccentric adjusting sleeve abuts in above straight pin, is then coupled together in the other end of opening and straight pin spring.
Compared with prior art, the beneficial effects of the utility model are: this utility model versatility is good, easy to adjust, and centering precision is high, and product processing quality is reliable, and production efficiency is greatly improved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
