Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, specifically a batch machining fixture for acetabular test molds. Background Technology

[0002] A acetabular cup fitting is a tool required for hip joint surgery. The acetabular cup is roughly bowl-shaped, and to better integrate with the bone, multiple grooves are formed on its curved surface. In total hip replacement surgery, a fitting is required before replacing the acetabular cup. Each acetabular cup to be replaced is first fitted on the acetabular fitting before grinding and replacement can begin. Therefore, the fabrication of the acetabular fitting is also very important.

[0003] The current traditional processing technology involves fixing the casting with positioning fixtures before processing it. For example, the utility model with announcement number CN215470237U discloses a grinding gate positioning fixture for precision casting of bipolar cup hip joint implants, which includes a base plate, fixed jaws, movable jaws and a locking mechanism. The bipolar cup is placed on the base plate with the gate of the bipolar cup facing upward. Detachable heightening pads are fixed on the base plate on both sides of the bipolar cup. The fixed jaws are fixed on the base plate. The movable jaws are movably mounted on the base plate and can be locked and fixed on the base plate by the locking mechanism when the movable jaws move to any position in their stroke. The bipolar cup is clamped and fixed between the fixed jaws and the movable jaws.

[0004] Although the machining fixture described in prior art 1 achieves the fixation of the casting, it can only perform positioning machining on a single test mold during the actual machining process; the test molds of the acetabular cup are similar in shape, but their dimensions are different; when fixing test molds of different sizes, the machining fixture in the prior art needs to repeatedly align and clamp multiple test molds, which results in long processing time, low changeover efficiency, and increased production costs for the factory. Utility Model Content

[0018] The cooperation between the limiting surface and the locking element allows for the fixing of test molds of different sizes within the first limiting area formed between the locking element and the limiting surface, facilitating subsequent processing.

[0019] By setting several positioning and locking pins, multiple test molds can be processed simultaneously, further improving the processing efficiency of the test molds and avoiding repeated clamping and alignment of multiple test molds. Attached Figure Description

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] See Figures 1-4 This embodiment discloses a processing fixture for fixing the acetabular test mold 110. Specifically, it is a batch processing fixture for acetabular test molds, including a mounting plate 101 and positioning posts 102. There are a plurality of positioning posts 102, and the plurality of positioning posts 102 are fixedly connected to the mounting plate 101.

[0035] A plurality of locking posts 105 are mounted on the mounting plate 101. The locking posts 105 are coaxially arranged with the positioning posts 102. A locking element 104 is installed inside the locking post 105. A first limiting area for fixing the test mold 110 is formed between the locking element 104 and the positioning post 102. The locking element 104 is used to press the test mold 110 onto the locking post 105, and the locking element 104 is detachably connected to the locking post 105.

[0036] The positioning post 102 is provided with a limiting surface 103, and the positioning post 102 is coaxially arranged with the locking post 105.

[0037] In this embodiment, the locking member 104 is a locking bolt, and the locking post 105 is provided with a threaded groove for engaging with the locking bolt. The locking bolt is detachably connected to the locking post 105 through the threaded groove. The test mold 110 is provided with a threaded hole for engaging with the locking member 104. When the test mold 110 needs to be fixed, it is first fitted onto the positioning post 102. The limiting surface 103 on the positioning post 102 is inclined towards the axis of the locking post 105. After the limiting surface 103 contacts the inner wall of the test mold 110 of different sizes, it can limit the test mold 110 of different sizes. After the test mold 110 is positioned by the limiting surface 103, it is set on the... The threaded holes on the test mold 110 correspond to the threaded holes on the locking member 104. After positioning the test mold 110, the locking bolt is installed in the threaded groove and then rotated until the locking bolt in contact with the test mold 110 can press the test mold 110 onto the limiting surface 103. Through the cooperation of the limiting surface 103 and the locking member 104, test molds 110 of different sizes can be fixed in the first limiting area formed between the locking member 104 and the limiting surface 103, which facilitates subsequent processing. By setting several positioning pins 102 and locking pins 105, multiple test molds 110 can be processed simultaneously, further improving the processing efficiency of the test molds 110 and avoiding repeated clamping and alignment of multiple test molds 110.

[0038] In some embodiments, the limiting surface 103 is provided with a stepped groove 106 for cooperating with the test mold 110. After the stepped groove 106 contacts the inner wall of test molds 110 of different sizes, it can limit the size of the test molds 110. After the test mold 110 is positioned by the stepped groove 106, the threaded hole on the test mold 110 corresponds to the threaded hole on the locking member 104. After the test mold 110 is positioned, the locking bolt is installed in the threaded groove and rotated. The rotating locking bolt can press the test mold 110 into the stepped groove 106. By providing the stepped groove 106, it is possible to... Increasing the contact area between the test mold 110 and the positioning post 102 further improves the fixing effect of the positioning post 102 and the locking member 104 on the test mold 110. In this embodiment, the limiting surface 103 located above the stepped groove 106 can guide the test mold 110 after contacting test molds 110 of different sizes, so that test molds 110 of different sizes can move quickly into the stepped groove 106 corresponding to the size of the test mold 110 under the guidance of the limiting surface 103.

[0039] In some embodiments, the locking pin 105 is detachably connected to the mounting plate 101. In this embodiment, the locking pin 105 is threadedly connected to the mounting plate 101. This detachable connection allows the user to easily adjust the number and position of the locking pins 105 on the mounting plate 101 according to actual needs. In this embodiment, the locking pin 105 and the locking member 104 are threaded in the same direction and tightened clockwise. This ensures that after the locking member 104 and the locking pin 105 are engaged, rotating the locking member 104 will only tighten the locking pin 105, preventing it from loosening with the rotation of the locking member 104.

[0040] In some embodiments, a limiting part 107 is rotatably mounted on the locking member 104, and a second limiting region for limiting the test mold 110 is formed between the limiting part 107 and the limiting surface 103. The limiting part 107 is rotatably mounted on the locking member 104 via a bearing. After the limiting part 107 moves with the rotation of the locking member 104 to contact the test mold 110, the limiting part 107 can press the test mold 110 against the limiting surface 103 under the action of the locking member 104, so that the test mold 110 is fixed in the second limiting region. Furthermore, the limiting part 107 can prevent friction between the locking member 104 and the test mold 110 when the locking member 104 is fixing the test mold 110, thus avoiding wear on the surface of the test mold 110.

[0041] In some embodiments, the limiting part 107 is provided with an arc-shaped groove 108 for engaging with the surface of the test mold 110. By providing the arc-shaped groove 108, the contact area between the limiting part 107 and the test mold 110 can be increased, thereby further improving the fixing effect of the limiting part 107 on the test mold 110 after engaging with the limiting surface 103.

[0042] In some embodiments, an anti-slip pad 109 is installed in the arc-shaped groove 108. The anti-slip pad 109 is made of rubber material and has anti-slip texture. The anti-slip pad 109 can increase the friction between the arc-shaped groove 108 and the surface of the mold 110, so that the limiting part 107 will not rotate under the action of the locking member 104.

[0043] In some embodiments, a telescopic device is installed on the mounting plate 101, and a limiting frame is fixedly installed at the telescopic end of the telescopic device. The limiting frame has several limiting grooves. In this embodiment, the fixed end of the telescopic device is connected to the mounting plate 101, and the limiting grooves correspond one-to-one with the positioning posts 102. The limiting frame moves vertically downward under the drive of the telescopic device until the limiting grooves can press the corresponding test mold 110 onto the mounting plate 101, preventing the test mold 110 from rotating with the locking member 104 during the tightening process. After the locking member 104 and the limiting part 107 press the test mold 110 onto the limiting surface 103, the telescopic device drives the limiting frame to move vertically upward to reset, preventing the limiting frame from obstructing the test mold 110 and affecting its processing. In this embodiment, the telescopic device is a conventional telescopic rod structure in the prior art; its structure and function will not be described in detail here.

[0044] In some embodiments, the locking member 104 is provided with a slot 111. The slot 111 is used to cooperate with conventional tightening tools in the prior art, so as to facilitate the rotation of the locking member 104 to fix the test mold 110.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
