Further optimize, the clamp plate is bilayer structure, and the upper strata is the metal sheet, the length of metal sheet is the same with the distance between the clamp plate connecting seat tip of base both sides, processing has the through-hole on the metal sheet, and the through-hole position is relative from top to bottom with the through-hole position of clamp plate connecting seat, the lower part connection backing plate of metal sheet, the length of backing plate is shorter than the metal sheet, the material of backing plate is the material that hardness such as plastics or rubber are less than engine oil heat exchanger core hardness.
The technical effects are as follows: the fastener is perpendicularly connected the clamp plate connecting seat and is convenient with clamp plate locking and fastening effect is good, and the backing plate is located for the backing plate with the contact of machine oil heat exchanger core, prevents that the machine oil heat exchanger core from causing compression deformation and damaging when the clamping is fixed.
Further optimize, the fixed mounting strengthening rib of clamp plate connecting seat and base junction.
The technical effects are as follows: the stability of the clamp structure is enhanced.
The utility model has the advantages that: the utility model discloses simple structure through using this kind of anchor clamps, improves machine oil heat exchanger's manufacturing accuracy, production efficiency, reduction in production cost, alleviates operating personnel's intensity of labour.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in FIG. 1 and FIG. 2, the utility model provides a machine oil heat exchanger core expands and connects and uses anchor clamps, including base 1, clamp plate 2, fastener 3. Place machine oil heat exchanger core 6 on the base 1, clamp plate 2 presses on machine oil heat exchanger core 6, and fastener 3 is long bolt and nut assembly, and the through-hole that penetrates clamp plate connecting seat 4 after the long bolt passes the through-hole on clamp plate 2 passes through the nut with long bolt locking, presss from both sides machine oil heat exchanger core 6 between clamp plate 2 and clamp plate connecting seat 4. The function of the expansion joint is to compress the engine oil heat exchanger core body 6 in a fastening state, so that the engine oil heat exchanger core body is always tightly attached to the base 1 in the expansion joint process and does not generate bending deformation.
As shown in fig. 3 and 4, base 1 is the cuboid, is formed by the steel sheet welding, and base 1's length slightly is less than the length of machine oil heat exchanger core 6, and the symmetrical welding has four group's clamp plate connecting seats 4 on base 1 along two sides of length direction, and the processing has the through-hole on clamp plate connecting seat 4 for installation fastener 3, machine oil heat exchanger core 6 places on base 1, and clamp plate 2 presses on machine oil heat exchanger core 6 upper portion.
As shown in fig. 5, the pressing plate 2 is a strip and is formed by bonding a metal plate 201 and a backing plate 202, through holes are processed at two ends of the metal plate 201, the through holes are vertically opposite to the through holes of the pressing plate connecting base 4 and used for installing fasteners, the length of the metal plate 201 is the same as the distance between the ends of the pressing plate connecting bases 4 at two sides of the base 1, the backing plate 202 is bonded at the lower part of the metal plate 201, the length of the backing plate 202 is shorter than that of the metal plate 201, and the backing plate 202 is made of plastic or rubber and other materials with hardness lower than that of the engine oil heat exchanger core.
When the clamp is used, the assembled engine oil heat exchanger core body 6 is arranged on the base 1, one side of the plastic cushion block of the pressing plate 2 faces the engine oil heat exchanger core body 6, the pressing plate 2 and the pressing plate connecting seat 4 are locked and tightly pressed on the engine oil heat exchanger core body 6 through the fastening piece 3, and after the clamp is assembled, expansion joint operation is carried out on the engine oil heat exchanger core body 6.
