Abstract
The invention relates to a ceramic bending clamp with a variable span. The ceramic bending clamp comprises two lower support rollers in parallel and further comprises support pieces positioned at both ends of the lower support rollers; both ends of each lower support roller are connected with the two supporting pieces through springs; vertical distance between the two lower support rollers is recorded as a span. The ceramic bending clamp is characterized in that each support piece consists of a first part at the upper part of the support piece and a second part at the lower part of the support piece; the first part is a span support part supported between the two support rollers; the clamp further comprises at least a positioning block; and the second part on the support piece extends towards both sides in a span direction to form a positioning groove for holding the positioning block; and the positioning block is clamped between the two lower support rollers on the back of the positioning groove of the support piece. With the adoption of the ceramic bending clamp with the variable span, the span between the two lower support rollers can be adjusted by additionally installing the positioning block in the positioning groove of the support piece, so that the width of the support part is adjusted, namely that the span between the two lower support rollers is adjusted; and the span can be conveniently and rapidly adjusted in no need of changing the support pieces with different spans, thereby the work efficiency of the test is improved.
Description
Technical field
The present invention relates to a kind of ceramic bending strength test device, specifically a kind of ceramic bending strength test three-point bending fixture.
Background technology
At present, three-point bending fixture according to < < GB/T 6569-2006-fine ceramics bending strength test method > > design, includes two lower backing rolls, support chip.Two lower backing rolls are parallel to each other, for ceramic sample is supported.Vertical range between two lower backing rolls is designated as span.
The two ends of every backing roll are connected with support chip by spring respectively.Span between two backing rolls struts maintenance by support chip top.
Complete the change that becomes span, must change supported on both sides sheet.The support chip that needs so former span on clamper for disassembling, more other span support chip is installed as required, changes more loaded down with trivial detailsly, and test efficiency is lower.
Summary of the invention
The shortcoming existing in order to overcome above-mentioned prior art, the object of the present invention is to provide a kind of variable span pottery bending fixture, and it is simple to operation that this fixture is adjusted span, can improve test efficiency.
In order to address the above problem, the present invention by the following technical solutions: a kind of variable span pottery bending fixture, comprise two parallel lower backing rolls, also comprise the support chip that is positioned at lower backing roll two ends; The two ends of described every lower backing roll are connected with two support chips by spring respectively; Vertical range between two lower backing rolls is designated as span; Each support chip is comprised of superposed first and the second portion that is positioned at bottom; First is for supportting the span support section between two lower backing rolls; This fixture also includes at least one locating piece; On described support chip, second portion extends to both sides for placing the detent of described locating piece in span direction; After described locating piece is installed in the detent of support chip between two lower backing rolls.
The invention has the beneficial effects as follows: it adjusts the width of span support section by install locating piece additional in the detent of support chip, adjusts the span between two lower backing rolls.Need not change the support chip of different spans and can conveniently adjust span, improve experiment work efficiency.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is described further:
Fig. 1 is the front view of the embodiment of the present invention;
Fig. 2 is the left view of the embodiment of the present invention;
Fig. 3 is the vertical view of the embodiment of the present invention.
In figure: 1 seaming chuck support, 2 locating pieces, 3 ceramic samples, 4 detents, 5 lower backing rolls, 6 support chips, 61 firsts, 62 second portions.
Embodiment
As shown in Figure 1, 2, 3, this variable span pottery bending fixture, comprises two parallel lower backing rolls 5, also comprises two support chips 6 that are positioned at lower backing roll 5 two ends.The two ends of described every lower backing roll 5 are connected with two support chips 6 by spring respectively; Vertical range between two lower backing rolls 5 is designated as span.Two lower backing rolls 5 are for supporting ceramic sample 3, and the top of ceramic sample 3 arranges pressure roller and seaming chuck support 1.
Each support chip 6 is comprised of superposed first 61 and the second portion 62 that is positioned at bottom; First 61 is for supportting the span support section between two lower backing rolls 5.
This fixture also includes at least one locating piece 2; On described support chip 6, second portion 62 extends to both sides for placing the detent 4 of described locating piece 2 in span direction; Described locating piece 2 be installed on the detent 4 of support chip 6 interior after between two lower backing rolls 5.
While locating piece 2 not being installed in the detent 4 of support chip 6, lower backing roll 5 is under the elastic pulling force of spring, and lower backing roll 5 can be attached on the two sides of first 61 of support chip, and at this moment the span between two lower backing rolls 5 is a fixed number.
While wanting to change span, only need pull out gently lower backing roll 5, locating piece 2 is inserted in locating slot 4, can complete the change of span.
