Description

Technical Field

[0001] The utility model belongs to the field of connecting rod processing, and particularly relates to a clamp for boring connecting rods. Background Art

[0002] When the connecting rod is processed, it needs to go through milling, boring, sawing, clamping and other processes. Most of the processes require clamping, such as Figure 6 The figure shows the common structure of a connecting rod, which is divided into a connecting rod body and a connecting rod cover. During the processing, the mounting holes need to be precision bored to facilitate a more precise connection between the connecting rod body and the connecting rod cover.

[0003] Since the outer surface shape of the connecting rod is irregular, the fixtures for the connecting rod are matched with the outer dimensions of the connecting rod. When processing the above-mentioned holes, the existing fixtures are difficult to adapt to connecting rods of different sizes. Even for the same connecting rod, the fixtures for the connecting rod body and the connecting rod cover require different clamping and positioning methods. Therefore, a fixture with strong compatibility is needed. Utility Model Content

[0004] The purpose of the present utility model is to provide a connecting rod boring fixture in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A clamp for boring connecting rod holes, comprising a base, a clamp back plate arranged on the base, a main clamp cooperating with the clamp back plate, and a side clamp arranged on the base, wherein the side clamp comprises a pair of sliding seats that move relative to each other on the base, and the sliding seats are provided with a plurality of sliding members for laterally clamping and positioning the connecting rod body, and the initial position of the sliding members is adjusted by adjusting members, wherein the ends of the sliding members are provided with layered spaced clamping members, the clamping members at the ends of the opposing sliding members are staggered and interlocked, and the opposing sliding members are respectively provided with docking blocks and docking grooves that are plugged into each other.

[0007] As a further optimization scheme of the present invention, the docking block and the docking groove are both arranged in a direction perpendicular to the clamping member, and the length of the docking block and the docking groove along the axial direction of the sliding member is not longer than the length of the clamping member along this direction. By arranging the docking block and the docking groove, the middle parts of the two sliding members can be docked to form a new placement platform, which can be used to place connecting rods of different lengths, or the mating surface of the connecting rod cover can be directly placed on the placement platform. For longer connecting rods, the function of the sliding member is side clamping, and the handle of the connecting rod body is clamped from the side by the clamping member.

[0008] As a further optimization scheme of the present invention, the main clamp includes a fixing part arranged on the base, and a clamping part corresponding to the clamp back plate is provided on the fixing part, wherein the clamping part is guided by a guide member and provides a clamping thrust through a clamping member, and the clamping member can be a bolt or an electric device.

[0009] As a further optimization scheme of the present invention, the sliding seat is driven by a bidirectional screw arranged in the base to move relative to it. The bidirectional screw is driven to rotate by a driving device or a manual device. When the bidirectional screw drives the sliding seat to move, the pre-positioned sliding part is clamped.

[0010] As a further optimization solution of the present invention, a first base and a second base are vertically arranged on the sliding seat, wherein the first base is used for the sliding member to pass through and slide horizontally, and the second base is used for installing the adjusting member.

[0011] As a further optimization solution of the present invention, the adjusting member is a threaded rod screwed onto the second base, and an internal threaded hole is axially provided at the end of the sliding member. By rotating the threaded rod, the sliding member reaches the clamping position.

[0012] The beneficial effects of the present invention are:

[0013] The utility model plays a major clamping role by arranging a main clamp to clamp the front and rear faces of the connecting rod body and the connecting rod cover. The handle of the connecting rod body that cannot be clamped is clamped by the side clamp to play a role of straightening and positioning. For connecting rod bodies of different sizes, in order to maintain the height of their upper ends, the sliding parts at the bottom can be docked with each other to form a placement platform, and connecting rods of smaller sizes can be placed on the platform to accommodate connecting rods of different sizes.

[0021] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1-5 As shown, a clamp for boring connecting rod holes includes a base 1, a clamp back plate 2 set on the base 1, a main clamp 3 cooperating with the clamp back plate 2, and a side clamp 4 set on the base 1. The side clamp 4 includes a pair of sliding seats 41 that move relative to each other on the base 1, and a plurality of sliding members 44 for laterally clamping and positioning the connecting rod body 501 are set on the sliding seat 41. The initial position of the sliding member 44 is adjusted by the adjusting member 49, wherein the end of the sliding member 44 is provided with a layered spaced clamping member 45, and the clamping members 45 at the ends of the opposing sliding members 44 are staggered and interlocked, and the opposing sliding members 44 are respectively provided with a docking block 47 and a docking groove 46 that are plugged into each other.

[0024] This solution plays a major clamping role by setting up a main clamp to clamp the front and back faces of the connecting rod body 501 and the connecting rod cover 502. The handle of the connecting rod body 501 that cannot be clamped is clamped by the side clamp 4 to play a role in straightening and positioning. For connecting rod bodies 501 of different sizes, in order to maintain their upper end height, the sliding parts 44 at the bottom can be docked with each other to form a placement platform, and smaller connecting rods can be placed on the platform to accommodate connecting rods of different sizes. Similarly, the connecting rod cover 502 can also be placed at a suitable height.

[0025] The docking block 47 and the docking groove 46 are both arranged in a direction perpendicular to the clamping member 45, and the length of the docking block 47 and the docking groove 46 along the axial direction of the sliding member 44 is not longer than the length of the clamping member 45 along this direction. By arranging the docking block 47 and the docking groove 46, the middle parts of the two sliding members 44 can be docked to form a new placement platform, and the docking groove 46 and the docking block 47 make the placement platform stable and will not be deformed by pressure.

[0026] The main clamp 3 includes a fixing portion 31 arranged on the base 1, and a clamping portion 32 corresponding to the clamp back plate 2 is provided on the fixing portion 31, wherein the clamping portion 32 is guided by a guide member 33 and provides a clamping thrust through a clamping member 34, and the clamping member 34 can be a bolt or an electric device.

[0027] The sliding seat 41 is driven by a bidirectional screw 42 arranged in the base 1 to move relative to it. The bidirectional screw 42 is driven to rotate by a driving device or a manual device. When the bidirectional screw 42 drives the sliding seat 41 to move, the pre-positioned sliding member 44 forms a side clamp. It should be noted that the initial position of the sliding member 44 needs to be debugged and verified. When processing a batch of connecting rods, the position of the sliding member 44 is first adjusted to make it conform to the contour of the part to be clamped to play the function of clamping and positioning. If necessary, the sliding members 44 are docked with each other. During processing, the sliding seat 41 only needs to move slightly driven by the bidirectional screw 42 to complete side clamping / release.

[0028] A first base 43 and a second base 48 are vertically arranged on the sliding seat 41 , wherein the first base 43 is used for the sliding member 44 to penetrate and slide horizontally, and the second base 48 is used for installing the adjusting member 49 .

[0029] The adjusting member 49 is a threaded rod screwed onto the second base 48 . The rotation of the adjusting member 49 has damping. An internal threaded hole is axially provided at the end of the sliding member 44 . The sliding member 44 reaches the clamping position by rotating the threaded rod.

[0030] The specific implementation method is as follows: when boring a batch of connecting rods, first adjust and check the sliding member 44 to make it conform to the contour of the connecting rod. During the check, taking the connecting rod body 501 as an example, make the hole 503 that needs to be fine-bored face upward, put the connecting rod body 501 in, adjust the sliding members 44 opposite to each other, make the adjusting member 49 rotate the same number of circles until it is clamped, and then adjust the sliding members 44 in turn. If the connecting rod body 501 is shorter and some sliding members 44 cannot be clamped, the sliding members 44 will be docked with each other to form a platform for placing the connecting rod body 501. After the positioning is completed, the sliding seat 41 is slightly moved to perform the function of clamping or releasing. After the connecting rod body 501 is placed in, it can be fixed for fine boring. Similarly, when processing the connecting rod cover 502, since it has no handle, its mating surface 504 can be directly placed on the docked sliding member 44 and clamped and positioned from both sides.

[0031] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
