Abstract
The utility model belongs to a field of automotive brake testing technology and relates to an improvement of a sliding table locking mechanism of an automotive brake tester. A locking force adjusting structure of the sliding table locking mechanism of the automotive brake tester includes a sliding table (1), a pedestal (2), a T-shaped bolt (3) and a locking cylinder (4). It is characterized in that a gap between the locking cylinder (4) and an installation hole of the locking cylinder is no large than 0.2 mm. Male threads are arranged on an outer cylindrical surface in the upper part of cylinder body of the locking cylinder (4). An adjusting nut (5) and a locking nut (6) are threaded on the outer threads in the upper part of the cylinder body of the locking cylinder (4). The lower end face of the adjusting nut (5) fits with the upper surface of the sliding table (1). The lower end face of the locking nut (6) fits with the upper end face of the adjusting nut (5). The locking force adjusting structure of the sliding table locking mechanism of the automotive brake tester in the utility model is convenient for adjusting a locking force of the sliding table locking mechanism of the automotive brake tester. The locking force adjusting time is shortened substantially and the adjusting efficiency is improved.
Description
Technical field
The utility model belongs to the automotive brake experimental technique, relates to the improvement to automotive brake test unit slide unit latch mechanism.
Background technology
Utility application " automotive brake test unit slide unit latch mechanism " (application number: 201120367262.3) disclose a kind of automotive brake test unit slide unit latch mechanism.In this latch mechanism, the cylinder body of locking cylinder passes through screw retention on the upper surface of slide unit.The shortcoming of this structure is: when a plurality of locking cylinders of needs are locked slide unit jointly; Because the relative position of cylinder body and slide unit can not be regulated, and needs to guarantee the consistance of a plurality of locking cylinder coupling mechanism forces, make the adjusting of coupling mechanism force relatively more difficult; It is long to regulate the used time, and adjusting efficient is very low.
Summary of the invention
The purpose of the utility model is: propose a kind of automotive brake test unit slide unit latch mechanism coupling mechanism force adjustment structure of being convenient to regulate coupling mechanism force, to shorten the adjusting time of coupling mechanism force, improve and regulate efficient.
The technical scheme of the utility model is: automotive brake test unit slide unit latch mechanism coupling mechanism force adjustment structure; Comprise slide unit 1, base 2, tommyhead bolt 3 and locking cylinder 4; Base 2 be positioned at slide unit 1 below; At base 2 upper surfaces the trend T-slot parallel with the moving direction of slide unit 1 arranged; The tommyhead bolt head of tommyhead bolt 3 is positioned at T-slot, and on slide unit 1, there is a locking cylinder mounting hole position corresponding with the T-slot of slide unit 1, the threaded end of tommyhead bolt 3 is screwed in the tapped blind hole of the piston-rod lower end face in the locking cylinder 4; It is characterized in that; Locking cylinder 4 is not more than 0.2mm with the gap of locking cylinder mounting hole, on the external cylindrical surface on locking cylinder 4 cylinder body tops, external thread is arranged, and the external thread on locking cylinder 4 cylinder body tops upwards stretches out the upper surface of slide unit 1; A setting nut 5 and a set nut 6 are arranged; Setting nut 5 is screwed on the external thread on locking cylinder 4 cylinder body tops with set nut 6, and the upper surface of the lower surface of setting nut 5 and slide unit 1 is fitted, and fits in the upper surface of the lower surface of set nut 6 and setting nut 5.
The utility model has the advantages that: be convenient to accurately regulate the coupling mechanism force of automotive brake test unit slide unit latch mechanism, shortened the adjusting time of coupling mechanism force greatly, improved adjusting efficient.An embodiment of the utility model regulates the coupling mechanism force of 6 locking cylinders through evidence, and the adjusting time was less than 20 minutes; If adopt original structure, need 8 hours at least, the adjusting time of the utility model has shortened more than 20 times.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Explain further details in the face of the utility model down.Referring to Fig. 1; Automotive brake test unit slide unit latch mechanism coupling mechanism force adjustment structure; Comprise slide unit 1, base 2, tommyhead bolt 3 and locking cylinder 4; Base 2 be positioned at slide unit 1 below, at base 2 upper surfaces the trend T-slot parallel with the moving direction of slide unit 1 arranged, the tommyhead bolt head of tommyhead bolt 3 is positioned at T-slot; On slide unit 1, there is a locking cylinder mounting hole position corresponding with the T-slot of slide unit 1, the threaded end of tommyhead bolt 3 is screwed in the tapped blind hole of the piston-rod lower end face in the locking cylinder 4; It is characterized in that; Locking cylinder 4 is not more than 0.2mm with the gap of locking cylinder mounting hole, on the external cylindrical surface on locking cylinder 4 cylinder body tops, external thread is arranged, and the external thread on locking cylinder 4 cylinder body tops upwards stretches out the upper surface of slide unit 1; A setting nut 5 and a set nut 6 are arranged; Setting nut 5 is screwed on the external thread on locking cylinder 4 cylinder body tops with set nut 6, and the upper surface of the lower surface of setting nut 5 and slide unit 1 is fitted, and fits in the upper surface of the lower surface of set nut 6 and setting nut 5.
The principle of work of the utility model is: coupling mechanism force as requested and locking cylinder piston area are calculated locking cylinder top oil pressure, simultaneously all locking cylinders are pressurized to desired pressure with a hydraulic hand-pump, and the piston of locking cylinder is under the promotion of hydraulic oil; The spring of compression bottom, piston rod drives tommyhead bolt 3 and moves downward, thereby makes the faying face of tommyhead bolt 3 upper surfaces and T-slot the gap occur; At this moment, rotation adjusting nut 5 is upwards put forward locking cylinder integral body; After the faying face of tommyhead bolt 3 upper surfaces and T-slot is fitted, tighten set nut 6 locking setting nuts 5, open the hydraulic hand-pump stop valve at last; Lay down the oil pressure of locking cylinder; Under the effect of locking cylinder lower springs, locking cylinder is locked at slide unit on the base tightly, accomplishes the locking cylinder coupling mechanism force and regulates.
